The Difference Between Metal and Wood Lathe Chucks

Posted on by

A lathe chuck is a clamp that is used for holding the lathe’s rotating tool bits. You can find the lathe chuck in a push or a pulled design. The push version is tapered and works by using a threaded cup. This pushes the bit deep into the socket to make the clamp. The pulled design has a section that is threaded near the back of the tool. This pulls the chuck in tight by use of the grooves.

 

Lathe Chuck Information

The lathe chuck can be used for either metal or wood lathes. It is important to know the differences between them so that you will be able to choose the right one for you. Of the different models, the most popular is the three and four jaw. The grip on the cutting tools and drill bits is firmer which is necessary for harder materials. When thinking about cost, the wood lathe will cost you less than a metal one. However, you need to consider what types of jobs you wish to do before deciding what one to buy.

 

Information on Wood Lathe Chucks

The size for wood lathe chucks is most often 0.25” or 0.50”. However, you can find them in other sizes if necessary. These are used to turn wood for a bowl, pens, cue sticks, baseball bats, table legs, etc. Because wood lathes are not as sturdy, the motor does not have to be nearly as powerful as a metal lathe. A wood lathe should not be used for materials that are harder than wood. Wood Lathes turn faster and do not make cuts that are as precise as metal lathes. While they are less expensive than metal lathes they do not make very good substitutes.

 

Information on Metal Lathe Chucks

Metal lathe chucks are used for hard materials. A metal lathe has a much more powerful motor than a wood lathe. You can also guarantee more precise cuts from a metal lathe. A metal lathe does not need to be hand held. The tool itself is incorporated into the machine that you use. A metal lathe chuck itself is a heavier tool when compared to a wood lathe. If necessary, you can use a metal lathe for any wood projects that you may have.

 

Some Safety Tips

When using a lathe, whether it is metal or wood, safety glasses should always be worn. These will help protect your eyes from debris and dust. You should never wear gloves when using these machines as the gloves can easily get tangled while the machine is in use. You should also never wear loose-fitting clothing for the same reason. If your hair is long, then you should have it tied back while using these machines. You need to wear protective footwear, preferably steel-toe boots. Some woods contain dust that can be hazardous to your health. Wear a helmet that has a respirator built in or a dust mask. Be sure to thoroughly read the manual for this machine before you attempt to use it.

The Best Crossbow Accessories and Why You Need Them

Posted on by

Crossbow hunting has become a very popular sport over time, and it has also opened up a lot of opportunities for those who are passionate about hunting. This hunting season, if you’re a beginner who is gearing up to start hunting, there are a few basic things you must know.

 

Most good quality crossbow hunting kits come with all the gear required, except for the broadheads, which you need to test out and pick according to your needs. Apart from that, there are also other accessories for a crossbow that can greatly make the sport a safer one, and also increase your odds of having a successful hunting trip.

 

Let’s take a look at these and understand what they help with:

 

For Better Performance:

  • Lighted Nocks – it’s a known fact that crossbow arrows travel at a great speed when they are shot. It’s almost impossible to track a moving arrow with the naked eye, and it also penetrates the target with a lot of force, so retrieving the arrow can be quite a task. Lighted nocks are a more recent invention, but even the conservatives are seeing its advantages and have started using them.

 

These nocks help with identifying your arrow once it has been shot, so it also helps with marking the trajectory. Also, these nocks are extremely lightweight and do not affect the speed or direction of the arrow in any way.

 

  • Reducing Noise – crossbow range has been designed to be very quiet and swift, but even further reduction of vibration and noise can make a significant difference to your hunting experience. There are special notice cancellation kits available that can assist with increasing the stealth and performance of your crossbow. Another great tip for reducing notice would be to use heavier broadheads or target points.

 

Improving Accuracy:

  • Scopes For Precision – a precision scope can make a lot of difference to the accuracy of your shots, and actually make the hunting process a much more feasible and convenient one. Unless you’re a thorough professional with an exceptional free-hand shot, using a scope is essential.

 

  • Support For Shooting – Shooting sticks are finally becoming popular, unlike earlier times when shooting from rest wasn’t exactly a preference amongst hunters. Shooting sticks can easily be used in the tree stand, does not obstruct the handling of the bow and also folds up very easily, making it convenient to use. For a hunting game that involves precision shots with minimal movement, they would be a very helpful assistant.

 

  • Using A Rangefinder – Judging distance and range with the naked eye can be a very tough ordeal even for an experienced shooter, so for a beginner, it can prove to be a waste of time. This is where a rangefinder comes in handy; to give accurate readings and judgement.

 

Protecting Your Equipment:

  • Case For Your Crossbow – Your crossbow’s strings, cams and wound cables require protection, especially if you’re hunting on the go and traveling a lot with it. There are a bunch of good quality cases available, and it’s definitely mandatory to have one if you want to protect the hardware of your crossbow from damages.

 

  • The CUB – it stands for Crossbow Unloading Bolt and is a great way to finish off a hunt. Target of hunting arrows can be quite expensive, so you could alternatively use a CUB which is a biodegradable, two-piece arrow that costs much lesser and is just as effective. Shooting your bow towards the end of each day can help you check the precision and functionality of your bow, so using a CUB will reduce any unnecessary costs too.

 

Some More Crossbow Accessories:

  • Sling – it can help with carrying your bow around more conveniently. Especially while going through dense forests, your bow might get caught in branches of the string might get cut, so a sling can make it more secure.

 

  • Targets – these are important for any practice session, and really do help with getting your angling and momentum right on point.

 

  • Arrow Puller – this will help with ensuring that you have a safe and proper grip while removing your crossbow arrows.

 

With all these accessories added onto your kit, there’s absolutely no way your hunting sessions won’t be memorable and interesting!

 

If you have any interest in more choice of crossbow accessories, I recommend that you can visit Man Kung Enterprise Co., Ltd. – the company specializes in kinds of archery bow and crossbow accessories. Get more details about archery products, please do not hesitate to contact with Man Kung!

Types of Screen Changer for Plastic Machines

Posted on by

Screen Pack Assembly

Screen pack with breaker plate used to remove any contamination. For more details on screen pack, breaker Plate and sources of contamination you can visit article: “Screen Pack and Breaker Plate for Plastic Extruder Machine”

 

Today’s topic is how the screens are changed and what are the methods to change the screen?

 

When It’s A Need To Change The Screen?

Every plastic (extruder) machines have a load meter. Pressure increases with the blockage of screen. As screen blocks slowly with time after continuous use pressure began to rise and this rise in pressure can be noted by a pressure transducer/Gauge or by load meter. A pressure meter is used in auto screen changer and an upper limit of pressure is set. When melt pressure reach or cross that point auto screen changer get active and change the screen automatically. While in case of manual a liver connected to screen pack is used to change the blocked screen.

 

Types of Screen Changer
Manual Screen Changer FilterManual Screen Changer
In early days a pack of screen is bolted at the end of (Screw and Barrel) extruder and start of die some time an adapter is used between plastic machine (Extruder) and Die. Removal and then placing a new screen pack when need to be changed is much time consuming, difficult and an experienced person is required to perform this. To overcome these situations mainly to save time different types of screen changer are being used. Screen changer can be categorizing by following:

 

  • Manual Screen Changer With A Liver

Two screens are attached at the end of liver in such a way that if someone push the liver upward then upper screen comes at the front of extruder and when downs the liver then second screen comes in the front. At this time blocked screen is changed with new one. In these types of manual screen changers machines need to be stopped. It is the cheap equipment need less capital cost.

 

  • Auto Screen Changers:

Auto screen changers are further divided into categories

 

  1. Screen Changers with Hydraulic Arm

In these hydraulic type screens changer a hydraulic oil cylinder piston assembly is used to change the screen. It is also further divided into types like single and double piston. Single screen and two screens are on a cylinder piston assembly.

 

  1. Rotary Screen Changers

Rotary screen changer consists of a wheel with number of screens on it. It rotates in such a way that a single screen comes in front of extruder. It has advantages that process not need to be stopped to change the screen but its capital cost is high.

 

  • Continuous Screen Passing In Front of Machine Head

In this type a screen in belt like shape pass and continuous moves one side to other removing the contaminants. This type of screen changer is not very common.

Introduction of Globe Valves

Posted on by

Cast Steel Globe Valve

A globe valves is a linear motion valve and are primarily designed to stop, start and regulate flow. The disk of a Globe valve can be totally removed from the flowpath or it can completely close the flowpath.

 

Conventional Globe valves may be used for isolation and throttling services. Although these valves exhibit slightly higher pressure drops than straight=through valves (e.g., gate, plug, ball, etc.), they may be used where the pressure drop through the valve is not a controlling factor.

 

Because the entire system pressure exerted on the disc is transferred to the valve stem, the practical size limit for these valves is NPS 12 (DN 300). Globe valves larger than NPS 12 (DN 300) are an exception rather than the rule. Larger valves would require that enormous forces be exerted on the stem to open or close the valve under pressure. Globe valves in sizes up to NPS 48 (DN 1200) have been manufactured and used.

 

Globe valves are extensively employed to control flow. The range of flow control, pressure drop, and duty must be considered in the design of the valve to avert premature failure and to assure satisfactory service. Valves subjected to high-differential pressure-throttling service require specially designed valve trim.

 

Generally the maximum differential pressure across the valve disc should not exceed 20 percent of the maximum upstream pressure or 200 psi (1380 kPa), whichever is less. Valves with special trim may be designed for applications exceeding these differential pressure limits.

 

Advantages

  • Can be fast-acting
  • Precise control
  • Can be used in high-pressure systems

 

Disadvantages

  • High head loss
  • Large opening for disk assembly
  • Heavier than other valves
  • Cantilevered mounting of the disk to the stem
  • Low coefficient of flow
  • Not good for clean or sterile applications

 

The most common application of the globe valve is a standard water faucet. When the handle is turned, a disc is lowered or raised. When the disc is fully lowered, the water supply is shut off.

 

Typical Applications Of Globe Valves Include:

  • Cooling water systems where flow needs to be regulated
  • Fuel oil systems where flow is regulated and watertightness is of importance
  • High-point vents and low-point drains when watertightness and safety are major considerations
  • Feedwater, chemical feed, condenser air extraction and extraction drain systems
  • Boiler vents and drains, main steam vents and drains, and heater drains
  • Turbine seals and drains
  • Turbine lube oil system

Buying a Lathe: Spindles and Tailstocks

Posted on by

A key consideration when buying a new turning machine involves its spindle. Here’s an overview of what you need to know.

 

After considering what sorts of workpieces your turning machine will need to handle, and taking a good look at tooling options, it’s a good time to cover what kinds of spindles lathes might have, and what factors are good to keep in mind when choosing a new machine.

 

Belt-Driven or Direct-Drive Spindles

The spindle on a turning center is either belt-driven or direct-drive. Generally, belt-driven spindles represent older technology. They speed up and slow down at a lower rate than direct-drive spindles, which means cycle times can be longer. If you’re turning small-diameter parts, the time it takes to ramp the spindle from 0 to 6,000 rpm is significant. In fact, it might take twice as long to reach this speed than with a direct-drive spindle.

 

A small degree of positional inaccuracy may occur with belt-driven spindles, because the belt between the drive and the positional encoders creates a lag. With integral direct-drive spindles, this is not the case. Ramping up and down with a direct drive-spindle happens at a high rate, and the positional accuracy also is high, a significant benefit when using C-axis travel on live-tooling machines.

 

A2 Spindle Noses

Lathes are designed to have an American Standard spindle nose on the front of the spindle motor. Tapered spindle noses come in various sizes to hold the chuck or threaded spindle mount. A2 and B2 are both short-taper spindles; the only difference between them is the method in which the chuck is mounted. Type L refers to long-taper spindles and Type D features a camlock mounting used on many engine-lathe spindles.

 

The good news is, your machine tool manufacturer has the spindle nose selection worked out based on the size of the chuck, diameter of barstock you intend to machine and the horsepower needed. The spindle nose will be properly sized for the machine.

 

Spindle Speeds, Horsepower and Torque

Today’s CNC lathes are designed for specific ranges of stock diameters. Basically, you buy a machine to cut a specific, maximum workpiece diameter. If you’re cutting 2-inch-diameter barstock, the machine will be designed for running small diameters using higher-speed, 6,000-rpm spindles, and with the right amount of horsepower and torque.

 

Generally, big lathes have high torque (twisting power) due to the weight of the mass spinning in the chuck. As a rule, the bigger the workpiece and the slower the spindle speed, the more torque required.

 

If the parts you are running require a machine with a 10-inch, big-bore chuck, the spindle will be designed to deliver slower speeds at more horsepower. This creates the torque to take bigger cuts for more stock removal. As the cutter gets closer to the center of the stock, the machine will automatically speed up to, say, 700 rpm to maintain the proper surface footage. Obviously, it doesn’t make sense to use a big-bore lathe to do small-diameter work.

 

The operation that typically requires peak horsepower is heavy-duty, inner-diameter work, such as using big drills to make holes in the barstock before finish-boring. In this case, Z-axis horsepower might be the limiting factor. For example, a 2-inch drill may require a 20-hp spindle motor to get the force needed to perform this operation.

 

Programmable Tailstocks

A built-in, numerically controlled tailstock can be a valuable feature for automated processes. A fully programmable tailstock provides more rigidity and thermal stability. However, the tailstock casting adds weight to the machine.

 

There are two basic types of programmable tailstocks—servo-driven and hydraulic. Servo-driven tailstocks are convenient, but the weight they can hold may be limited. Typically, a hydraulic tailstock has a retractable quill with a 6-inch stroke. The quill also can be extended to support a heavy workpiece, and do so with more force than a servo-driven tailstock can apply. This is an advantage if you’re machining a piece that weighs, let’s say, 2,000 pounds. Using the programmable tailstock to push the part helps support its weight in the chuck.

 

If you have any interest in tailstocks, I recommend that you can visit Spintop Machinery Co., Ltd... You can find kinds of high quality tailstocks such as faceplate tailstock, automatic tailstock, center tailstock, and manual tailstock there. Get more details, please do not hesitate to check out Topsdisk’s website and feel free to contact them.

3 Types of Basin Wrenches Explained

Posted on by

Basin wrenches are plumbing instruments designed to remove nuts under sink basins or hard-to-reach spots. Nuts that connect the faucet to the sink are hard to reach and are, therefore, hard to remove. While other types of wrenches do not work on these types of nuts, basin wrenches can do the job easily.

 

This type of wrench can have either an adjustable self-tightening jaw or a fixed jaw that cannot be adjusted. This jaw is attached to the end of a torque tube that has a long handle. The long handle is intended to allow the user to reach hard-to-reach nuts under the sink. Since sinks usually are fastened to the faucet in deep recesses, loosening a nut may prove to be a difficult task when working with other types of wrenches. However, a basin wrench can reach a nut in such areas easily. It can grasp the nut and allow the user to either tighten it or loosen it. Below are three types of basin wrenches.

 

Fixed Basin Wrenches

Fixed basin wrenches have a fixed jaw that can only be used for certain types of nuts. It has two open-ended sockets. These sockets typically have a size of 22 mm and 15 mm. Fixed basin wrenches can be useful when you are working with uniformly-sized nuts frequently. These wrenches can also be purchased as a set with different sizes that can fit different types of nuts.

 

Adjustable Basin Wrenches

Some basin wrenches are also designed to be adjustable. Adjustable basin wrenches can fit through any size of nut. These wrenches have heads that tighten automatically as they wrap around nuts of different sizes. The main advantage of this type of basin wrench is its flexibility to adjust to any type of nut or coupling, making it a more preferred choice for consumers. In addition, it also saves money since you only need to buy one as compared to a set.

 

Adjustable basin wrenches are designed to have a head on one end that can be tilted up to 90 degrees. This allows the head to work on a nut in a vertical position while the handle is held in a horizontal position. There are two metal jaws on the head of the wrench. It is connected to the shaft by a spring-loaded hinge that allows it to grip all types of nuts with different sizes. For increased leverage, some models allow a bar to be added to the other end of the shaft. This proves useful for nuts that are situated in deeper crevices

 

When working with nuts, you can use both types of wrenches in order to have a working set that can fit any nut type or size. The cost of each individual basin wrench depends on the model and the manufacturer.

 

The Plastic Nut Basin Wrench

This type of wrench is a variation of the tool and is still called a basin wrench. This tool is used to remove or replace huge plastic mounting nuts used to secure furniture in place. This tool is actually a cylinder that has notches on one end designed to grab and turn plastic mounting nuts.

How To Choose A Motorized Valve?

Posted on by

Choose Valve Body:

Step 1: Determine The Working Pressure Of The Ball Valve

When the valve is closed, you must be sure that it is in the range of pressure.

 

Step 2: Determine The Temperature Range Of The Ball Valve

Valves are generally used to handle hot fluid or cold fluid. It is very important to determine how low or high temperature is the medium of the valve. There are different materials; such as ceramic, stainless steel, and PVC are used in the manufacture of valves. Each of them is applied to a certain temperature range.

 

Step 3：Determine What Kind of Fluid Through The Valve

Specific applications and fluid control systems are designed to handle different types of fluids. Some valves are used to deal with dams and reservoirs of hydroelectric power plants. There is also used for the normal flow of chemicals. There are a number of special designs, used for radioactive material, to ensure that the valve will not leak radiation.

 

It is also important to make sure whether the fluid is corrosive. These are helpful for choosing the body material. This step is also used to ensure the safety of the valve staff.

 

Step 4: Determine The Volume Of The Fluid

Different flow valve is designed for different purposes, is too thin or too thick are not suitable, so correct size of the valve is very important to choose the size of the valve.

 

Choose Actuator:

  • Torque Protection

To prevent motorized valve actuator in the middle of over torque, this function not only protects the valve, but also protects the actuator itself. The torque is set by the setting device.

 

  • Motorized Valve Position Limit Protection

Motorized valve actuator runs to close and open the limit position automatically stop (with a set of working modes).

 

  • Automatic Phase Adjustment

Electric actuator automatic detection of three-phase power supply terminal of the access, by the appropriate logic operation, the decision of the implementation of the operation of the mechanism when the AC contactor, in order to ensure the electrical connection to the right. If there is no automatic phase adjustment function may be due to damage to the valve and connection order error, Because of the automatic phase adjustment function, the actuator power supply wiring cannot consider the sequence.

 

  • Instantaneous Reversal Protection

When the motorized valve actuator receives commands for the opposite direction, it automatically adds a time delay, to prevent unnecessary wear of the valve shaft and gear box.

 

  • Power Shortage Phase Protection

Motorized valve actuator has a perfect power supply shortage protection function. It uses a combination of monitoring voltage and current method, It can’t only detect the phase of power supply when the motor is at rest, also can detect the power shortage in the operation of the motor. So that prohibits motor operation, to avoid the lack of phase operation caused by motor overheating Notice: The vast majority of the motor phase is in the motor running process.

 

  • Valve Stuck When The Protection

Whatever the motorized valve actuator to open or close the direction of action, the torque protection function is temporarily disabled within 5~10 seconds after the signal is sent to the motor. (If actuator doesn’t act in the time of the 5~10 seconds, Control circuit is cut off the power supply of the motor.) This feature can be achieved when the valve stuck solution card.

Types of Locking Washers and Their Uses

Posted on by

What is Lock Washer?

The locking washers can be made of metal or non-metal materials. The purpose in using them is to keep nuts and bolts from vibrating or friction loose. They are many different shapes and sizes, but they all try to achieve the same goal. When properly applied, lock washers provide a shabby, basic way to keep threaded fasteners steady over a long period of time.

 

Washer dimensions can come in either imperial or metric units. If you do not have a specific size most manufacturers will be able to custom build a washer to fit your application. Washers can follow ANSI, SAE, USS, and JIS sizes as well.

 

Below, there is a list of split lock, sealing, internal tooth, external tooth, flat, and flat retaining. And I will tell you what each one is and their use.

 

  1. Split Lock – Split locks are also called helical spring lock washers. These are made out of a spring coil that cut or split. This makes it so the two ends of the coil forced outward to the mating surface. So when the washer is fastened each end of the coil will bite into the surface of the head of the screw and to the surface to which you are fastening too.

 

  1. Sealing – Sealing washers use a form of a silicone rubber that is bonded to the steel of the washer. These are made to be used with screws, bolts, and nuts. They are a simple solution to any sealing needs. They have a seal on the bottom of the washer that seals the surface of the washer face, and a seal at the top that encases the shank and under the head of the fastener making a complete seal from top to bottom.

 

  1. Internal Tooth – Internal tooth have teeth on the inner dimension of the washer and the outside of the washer is smooth. They are made for fasteners who have a smaller head. When the head is fastened into the hole the internal teeth will help grab the surface, while at the same time resisting against the force of the washer being compressed.

 

  1. External Tooth – External tooth have teeth on the outer dimension of the washer so that they can actually bite into the surface that it is put on, and the inside is still a cylindrical hole. They are designed for fasteners who have a bigger head. When the head is fastened into the hole the external teeth will help grab the surface, while at the same time resisting against the force of the washer being compressed.

 

  1. Flat – Flat washers are used for basic applications, where the hole is cot directly in the center of the washer. Standard or metric, it does not matter they can accommodate all shapes and sizes.

 

  1. Flat Retaining – These have multiple holes in them so that you can screw or bolt down the washer, and the second hole would be for running your wire to the screw or bolt.

 

Where Can You Find The Locking Washer Supplier?

I recommend that you can visit the website of Chin Hsing Precision Industry Co, Ltd.

 

Chin Hsing is a professional and experienced manufacturer of metric lock washer with “CS” Brand. You also can find quality adapter sleeves, bearing lock nuts, and much more products there. Now, contact Chin Hsing at 886-5-2765634 for more details!

3 Benefits of Hydraulic Pumps

Posted on by

A pump is a device which has many purposes and can be used for various tasks and in various industries. Usually pumps are used to transfer certain substances like gas or liquid from one place to another. There are many types of pumps, but one particular which is widely used is the hydraulic pump. These pumps can be either hydrostatic or hydrodynamic and are used mostly in hydraulic drive systems. Gear pumps, rotary vane pumps and screw pumps are the three most commonly used types of hydraulic pumps. All are used in many different industries.

 

Whereas most pumps use some external power source to operate, hydraulic pumps use the kinetic power of the water as their main source for operation. They are very durable, easy and relatively cheap to maintain and very practical. These pumps are also very efficient which is why they are common in many industries and inevitable tool for many companies. Here are few major benefits of hydraulic pumps.

 

The hydraulic pumps are very useful source of energy and power for many machines. They have a capability and are designed to push large amount of fluid through a metal cylinders. This is how these pumps transform mechanical energy into hydrostatic energy. Hydraulic pumps have been used for many years, but their popularity slowly dropped with the emergence of the electric and solar pumps. However, today, the interest for hydraulic pumps has increased as it is a very effective device for providing clean drinking water in rural areas or in the financially unstable countries which have battle the lack of water problem.

 

Also these pumps are widely used by government agencies when dealing with certain types of natural disasters such as floods. In the case of a flood, hydraulic pumps will quickly and effectively pump out excess water to reduce the overall damage to some extent. Households located in flooding areas should have one of these. They may look complicated but are really very easy to use and maintain and can find usage even in the most remote places. One of the biggest benefits that a hydraulic pump can provide is getting the water from underground sources that are not contaminated. The lack of clean water and the hygiene problems are major concerns in developing countries. The hydraulic pumps surely help a lot in solving such problems. This brilliant engineering invention can be used in almost any industry which is the main reason it is so popular.

What is UV Curing Resin?

Posted on by

UV curing resins are materials that are polymerized and cured in a short time by the energy radiated from ultraviolet irradiation devices. These are especially used as industrial materials for sealing, bonding, and coating.

 

Excellent Characteristics of UV Curing Resins:

  • Because the curing speed is fast, working hour is shortened.
  • Because they do not cure without UV irradiation, restrictions are few in the coating process.
  • They can cure at a low temperature.
  • Because of nonsolvent, one-part resin, they provide good workability.
  • A variety of cured features is available.

 

Because the products provide these advantages, cost reduction can be achieved in various fields.

 

Ultraviolet Irradiation Devices

  • Conveyor Type: Suitable for mass production of mid- and large-scale workpieces.
  • Spot Type: For bonding and partial temporary fixing of compact parts.
  • Handy Type: Built-in type in the production line.
  • Unit Type: For partial irradiation to experimental or large-scale workpieces.

 

Points To Select A Lamp Or A Lamphouse

  • Appropriate wavelength of the lamp Short wavelength is effective for surface curing and long wavelength for depth curing.
  • Enough emission intensity Select them considering the attenuation of the light intensity due to a long use of the lamp.

 

Please note especially above two points to choose the lamp and the lamphouse for a UV-radiation system.

 

Conclusions

As the UV curable resin is single-component and non-solvent, it does not contaminate the work environment with any solvent. This adhesive is cured within seconds. Its excellence in mass production significantly helps reduce the production processes.
