All about Metalworking Devices – ROTARY TABLE

Posted on by

Businesses in the metalworking industry usually invest in high quality tools and materials. This kind of work requires precision and attention to details. This is impossible without using the right machining devices and materials. People working in such business know that equipment plays a huge role in the production. If you are in this line of business, you should understand that productivity is dependent on the use of the right machines. Here are some tips on buying the right tools for metalworking.

 

Buying the Right Machining Devices

 

Quality should be a top concern when buying machining devices. Heavy machinery used in metalworking usually have to go through high levels of heat. This is why they should be durable enough to withstand the pressure of extreme heat. The work also involves dangerous chemicals. This is why it is important to choose the right grade of materials.

 

You should also remember the industry’s standards when choosing supplies and machineries. Following the strict standards of regulators helps ensure the quality of your products and improves your reputation in the field. Most consumers choose reputable suppliers who commit to the industry standards. They are more confident to do so because they will get products that have passed through several screenings and quality control measures.

 

You can find many companies specializing in supplies for metalworking businesses. You have to make sure, however, that you are making a deal with the right supplier. You need to know whether they are a licensed distributor. Working with appropriately registered companies gives you the right protection from the law whenever problems arise regarding the purchase.

 

ROTARY TABLE – Most Important Devices in a Metalworking Business

 

Other than the quality of products and your supplier’s reputation, you should also keep the unique requirements of your business in mind. Precision is one thing that takes priority in this line of business. This means you should invest in quality precision devices. This is where you should think about finding a dealer of rotary tables. This type of device makes it possible for a metalworker to drill and cut the material on fixed axes and specific intervals.

 

Rotary tables come in different types such as the direct drive high speed rotary table. Some of them allow the metalworker to use indexing plates, while some make it possible to fit dividing tables. A rotary table is one thing metal working businesses cannot go without. Other than for the purpose of drilling holes, these tables are also useful in machining spanner flats on bolts and cutting round pieces with protruding tangs. Mixing helixes and cutting complex curves are also much easier with the help of rotary tables.

 

Rotary tables have different parts with different functions. The most important component is the work table. It consists of a spherical working area where four t-slots are used with clamps. These are used in mounting work pieces.

 

Now that you know the importance and uses of rotary tables, you should start looking for reputable suppliers of such devices.

Basic Overview of Sanitary Valves – Types, Specifications, and Body Material

Posted on by

Sanitary valves are designed for use in applications requiring clean or sterile processing. Sanitary valves are commonly used in dairy, food, pharmaceutical, medical, and chemical applications. Common features include easy cleaning, crevice free, and polished contact surfaces. Valve types include globe, diaphragm, pinch, knife or gate, needle, butterfly, ball, and plug.

 

Specifications

 

Important specifications when considering sanitary valves include diameter, working pressure, and operating temperature. The diameter is measured across the inlet or outlet port. The working pressure is the pressure at which the valve is designed to operate. The operating temperature is the full-required range of ambient operating temperature. Media types that sanitary valves can be configured to work with include gases, liquids, and liquids with suspended solids. The material temperature is the range of temperature that the valve can withstand and still function properly.  This relates to the media being transported, not the ambient or operating temperature outside of the system.

 

Body Material

 

The body material of sanitary valves can be metal or plastic. Metal choices include brass, bronze, copper, cast iron, ductile iron, stainless steel, and steel. Plastic choices include PVC and CPVC. Common end connections include threaded, socket-weld or butt weld, push on, solder end, clamp, grooved end, flangeless wafer-style, lugged, mechanical joint and flanged. Sanitary valve actuation types include electric, pneumatic, hydraulic, and manual.

 

ANSI Class ratings common to sanitary valves include Class125, Class 150, Class 200, Class 300, Class 600, Class 800, Class 900, and Class 1500. Other standards and specifications that sanitary valves can meet are API standards, MSS specifications, UL listings, ASME standards and federal specifications WW-V-35C.

What is a Grinding Machine?

Posted on by

A grinding machine uses an abrasive wheel as a cutting tool to shape or change the dimensions of a hard material. The types of materials that need grinding are usually metallic items such as tools and rods. These machines generally work by reducing the material through abrasion. Generally, the grain of the abrasive wheel chips away at the material, changing its shape or dimension.

 

Since the process of grinding metallic items often generates a great deal of heat, a coolant is often required to prevent the material and the machine from overheating. In high precision jobs, coolant may not be necessary. High precision grinding usually involves removing minute amounts of material, so very little heat is generated.

 

The basic parts that a user works with are typically the grinding machine’s power driven wheel, the work-bed where the material is placed, and a fixture which guides and holds the material. The wheels, which can vary in size, are generally made from a manufactured abrasive such as silicon carbide or aluminum oxide. Depending on the job, the grinding head can move along the material that is being worked on or the grinding head can be set to stay in a fixed position and the material can be moved around it. The grinding head and work-bed positions can be controlled with features such as a vernier calibrated hand wheel, numerical control, or computer numerical control.

 

There are several types of grinders. This is necessary because all of the machines are not designed to perform the same types of jobs. For example, a belted grinder is a power-driven grinding machine used to process metals with the aid of coated abrasives. These machines are generally used for three applications: finishing, deburring, and stock removal.

 

Bench grinders are generally manually operated machines that have two wheels. Each wheel is likely to have different grain sizes, which are used for roughing and finishing. These machines are commonly used to shape tools in need of repair, such as tool bits. They are also used to shape metal that needs to be welded. Their grinding wheels may have to be switched when working with harder or softer materials.

 

The jig grinder is used for a variety of functions involving jigs, dies, and fixtures. These machines can be used to grind complex shapes and holes with a high degree of accuracy. Jig grinders typically operate using a removable, high-speed air spindle to rotate the grinding bits. Whether the speed of a jig grinding machine is fixed or adjustable varies from one machine to another.

How Do I Choose the Best Eyelash Perm Kits?

Posted on by

The best eyelash perm kit is intended for at-home use, contain multiple applications, and have step-by-step simple instructions. These kits can help you to achieve a long-lasting eyelash curl, similar to the temporary results achieved by using a metal eyelash curler. Perming eyelashes can eliminate the need to curl eyelashes daily or to wear mascara. Eyelash perming kits are best handled and applied by a professional, but they are available for at-home use as well.

 

It may be difficult to find eyelash perming kits sold for at-home use due to the potential dangers associated with getting chemicals in the eyes. Choosing a kit that is intended specifically for at-home use will help ensure a smooth, injury-free eyelash perming experience. Kits intended only for use by salon professionals may not contain the detailed instructions needed by someone new to the eyelash perming process. If you attempt to use a kit at home, wear gloves at all times, and be sure to cleanse the eyes and eyelashes well after perming.

 

Browse reviews of eyelash perm kits to find a brand that has been satisfactory to other consumers, or ask for a recommendation in-person from an associate at a beauty supply store. The best kits contain pads for protecting the eyes and cleaning solution to remove the perming chemicals after the curling process is complete. Protecting the eyes from the perming chemicals used is of utmost importance. It may be useful to practice the eyelash rolling and setting techniques on a mannequin or on false eyelashes before attempting it on yourself. Watching online tutorial videos can also help clarify the process.

 

There are several dangers associated with eyelash perm kits. The U.S. Food and Drug Administration have not approved any perming kit. Using a kit at home instead of having a professional perform the task increases the risk, as it can be difficult to properly apply the solution to one’s own eyelashes. Self-perming can also negatively affect results, as errors in the process can lead to uncurled or lopsided lashes or can cause the lashes to fall out. If the perming solution accidentally comes into contact with the eyes, the eyes should immediately be flushed with water to prevent potentially serious damage.

 

An eyelash perm typically lasts two or three months, around the time it takes for eyelashes to grow out. Most kits come with multiple applications, and choosing one of these kits is often the most economical choice. The perm process usually takes about an hour. Some choose to combine perming with other eyelash-enhancing procedures, such as the application of false eyelashes or dye.

 

An innovative way to keep lashes curled, and offers a younger looking – Developed by professional pharmacologists, mild, safe and reliable – Effects are excellent and long lasting.

Introduction of Unidirectional Fabric

Posted on by

A unidirectional (UD) fabric is one in which the majority of fibres run in one direction only. A small amount of fibre or other material may run in other directions with the main intention being to hold the primary fibres in position, although the other fibres may also offer some structural properties. Some weavers of 0/90° fabrics term a fabric with only 75% of its weight in one direction as a unidirectional, whilst for others the unidirectional designation only applies to those fabrics with more than 90% of the fibre weight in one direction. Unidirectionals usually have their primary fibres in the 0° direction (along the roll ­ a warp UD) but can also have them at 90° to the roll length (a weft UD).

 

True unidirectional fabrics offer the ability to place fibre in the component exactly where it is required, and in the optimum quantity (no more or less than required). As well as this, UD fibres are straight and uncrimped. This results in the highest possible fibre properties from a fabric in composite component construction. For mechanical properties, unidirectional fabrics can only be improved on by prepreg unidirectional tape, where there is no secondary material at all holding the unidirectional fibres in place. In these prepreg products only the resin system holds the fibres in place.

 

Unidirectional Construction

 

There are various methods of maintaining the primary fibres in position in a unidirectional including weaving, stitching, and bonding. As with other fabrics, the surface quality of a unidirectional fabric is determined by two main factors: the combination of tex and thread count of the primary fibre and the amount and type of the secondary fibre. The drape, surface smoothness and stability of a fabric are controlled primarily by the construction style, while the area weight, porosity and (to a lesser degree) wet out are determined by selecting the appropriate combination of fibre tex and numbers of fibres per cm.

 

Warp or weft unidirectionals can be made by the stitching process. However, in order to gain adequate stability, it is usually necessary to add a mat or tissue to the face of the fabric. Therefore, together with the stitching thread required to assemble the fibres, there is a relatively large amount of secondary, parasitic material in this type of UD fabric, which tends to reduce the laminate properties. Furthermore the high cost of set up of the 0° layer of a stitching line and the relatively slow speed of production means that these fabrics can be relatively expensive.

 

TEI provides high quality Structural UD Fabric and UD Aramid Woven for customers. If you need more details about unidirectional fabrics, welcome to visit our website and feel free to contact Taiwan Electric Insulator Co. Ltd.

6 Key Factors to Consider When Buying Drum Sanders

Posted on by

Drum sanders are powerful and versatile in that they can be used as floor sander or bench sander among other uses. The market has a wide variety of models and brands and this means you would need to be a little careful when making your choice so that you can get a good drum sander for your use.

 

  1. Quality

The quality of the drum sander cannot be ignored because it directly affects functionality and durability. The ones made from alloys tend to be quite durable and make great investments. Look at the materials used and make sure you get yours from a distributor you can trust with quality brands and models.

 

  1. Speed

A good drum sander should have a speed that is easy to control. Variable speeds are very important because not all uses can use just one speed, hence you are better equipped if you can adjust the speed to match the use. High speeds are great for more polishing but other applications achieve best results with slow or moderate speed.

 

  1. Platen

This is the recumbent part on the tool’s lowest part. Your drum sander should have a platen that is constructed to withstand friction and vibration of daily normal operations. Platen that measures around an inch wider than the drum in terms of width definitely makes a great choice.

 

  1. Drum

The drum is a very important part of the machine and should therefore be made from good materials. Aluminum that has self-cooling abilities is, for instance a very good material for the drum. This is because the cooling prevents heat damage to the sanding strip or wood under load. A unit that also has drum height that is adjustable is a good machine because it gives you more flexibility in using for various purposes.

 

  1. Dust collection

A machine that has a dust collection feature included is a good drum sander. The dust system helps in keeping the tool clean and safe in operation and also keeps dust from the hair and clothes of the drum sander operator. It is actually possible to find one that has a detachable vacuum system designed to make it more effective.

 

  1. Noise

Most drum sanders operate under distracting noise levels, but technological developments have made it possible to manufacture machines that have noise reduction features. A machine that has 95 decibels is considered to have non-harmful noise so be sure to check. Always look at the noise reduction features or noise levels before you go ahead and make your purchase.

 

Another important thing to consider when looking for a good sander is the levels of vibration. Important to remember is that excessive vibration can leave blabber marks on your stock or worse still it can lead to carpal tunnel syndrome. When buying, remember the weight can determine the levels of vibration with lighter drum sanders causing less vibration. You can also choose a model that has an anti-vibration design for safer and excellent operations.

What’s Inside A Fine Mist Sprayer and How Does It Work?

Posted on by

The plastic Fine Mist Sprayer is common for personal care and cleaning products that deliver a fine mist spray when the consumer is dispensing the product. Remember, there are hundreds of unique designs that could require different components then what we are showing here, but this article will give you a general idea of what makes a Fine Mist Sprayer work and how it can turn a stream of liquid into a mist.

 

These are the components that go into a Fine Mist Sprayer:

 

  1. Dust Cap: Often made of PP plastic and very often produced in clear, the dust cap serves as a dust cover and safety cap that protects the actuator from gathering dust and prevents an accidental actuation. To help the package stands out on the shelf, the dust cap can be produced in stock or custom color.

 

  1. Actuator: Commonly made of PP plastic, this is the component that consumer pushes down to spray the product out of the bottle. Different than an actuator on a Lotion Pump, the actuator of a Fine Mist Sprayer has internal components including an insert to create the specific misting pattern of the product being sprayed. Some Fine Mist Sprayers have locking features that prevent accidental dispensing.

 

  1. Actuator Insert: This tiny component consists of channels that the liquid flows through to create the mist pattern. This insert fits on the exterior of the actuator in many cases, and it is the part where the product exits the sprayer.

 

  1. Closure: The component that holds the entire assembly together onto the bottle. It is often made of PP plastic, and can come with many surface finishes or designs – including rib side, smooth, matte, or glossy finishes. A Metal Overshell can also be applied in some cases to further enhance the shelf appeal of the package. This component should have an industry standard neck finish such as 18-410, 20-410, 24-415, etc.

 

  1. Gasket: The external gasket serves as a compressible seal that seals the closure onto the land area of the bottle to prevent leaks. Depending on the product / chemical makeup, different gasket materials are required and it is a critical component that must be tested to ensure compatibility. It can be customized with different materials such as BUNA, Neoprene Rubber, Plastic Rubber, and LDPE.

 

  1. The Mechanism: commonly consists of many components such as the piston, housing cap, stem, spring, seal, and the overall housing, this is the part that transfers the product from the inside of the bottle to the actuator. Commonly speaking, the spring compress as the actuator is pressed downward, drawing the product through the dip tube to the interior of the housing. Subsequent actuation pumps the liquid upward through the piston towards the actuator and exits out of the pump via the actuator insert.

 

  1. Dip Tube: the long, thin plastic tube that extends the reach of the sprayer to the bottom of the bottle. Different than the dip tube of a Lotion Pump, which is often thicker, the dip tube of a Fine Mist Sprayer is often bent slightly to allow it to reach the bottom of the push up area of the bottle and cut either in a “V” shape or at the angle to avoid clogging.

 

The output of a Fine Mist Sprayer is often measured in mcl (micro-liter) or cc and is often offered in a range between 0.12 – 0.18cc.

The Differences between CAT, BT and HSK Tool Holder

Posted on by

BT & CAT tool holder – often referred to as “V-flange” by tooling manufacturers and machinists alike- is the most accepted and widely used standard of conventional milling tooling in the U.S. today. The “CAT” designation was developed by industrial conglomerate Caterpillar Inc. in order to standardize their machinery and has become the U.S. national standard. The “BT” series, on the other hand, is the Japanese equivalent and is more prevalent internationally, particularly in Europe since it was developed there. CAT and BT series holders are similar in that they both have the same 7:24 taper ratio and require the use of a retention knob, or pull stud, to secure the holder within the machine spindle (CAT tool holders generally have a standard thread while BT’s are mostly metric).

 

The difference between the two styles lies in the flange design where the BT bottom flange is thicker and engaged differently by the tool changer. Typical variations are CAT40, CAT50, BT30, and BT40 where the numerical portion signifies the taper dimension (the larger the number, the larger the holder). Because they are so similar, many CNC machine manufacturers and industrial tool suppliers offer the choice between CAT and BT spindles and there is some debate as to the efficacy of doing so. So why choose one over the other? Ease of tooling procurement. CAT tool holders are widely distributed in the U.S. while BT holders can be more easily procured internationally. But functionally speaking, there is little difference between the two.

 

There are some important limitations to note, however, when using CAT and BT systems. Both engage the CNC machine with a single-contact surface with a small gap existing between the flange of the tool holder and the spindle face. As a result, there can be inaccuracies that result from higher speeds that exceed 800 RPM’s, as centrifugal forces pull the holder up toward the spindle. While balanced holders help alleviate this problem, newer CNC clamping systems without this imitation- such as HSK- are rapidly gaining traction.

 

HSK is a German standard- translating to “Hollow Shank Taper” in English- that bears no resemblance to the CAT and BT styles mentioned above. The taper is much shorter and engages the spindle in a different fashion (i.e. no retention knob) with a cleverly designed dual contact method. The HSK system contains an internal clamping mechanism providing both radial and axial connection (thus the “dual contact”) providing a tremendous rigidity lacking in most CAT/BT set-ups. This allows for improved repeatability leading to increased tool life in high speed machining applications- the Holy Grail for production manufacturers.

 

Within the HSK family, there are 6 main styles (designated by letters “A-F” for differing applications) with HSK-63A being the most widely used today. While this style is becoming more popular, it does have some limitations. Due to the newer technology, HSK machine and tooling costs remain expensive and thus is not as popular among smaller manufacturers. However, for those engaged in machining high-value and precision parts, the HSK technology can offer tremendous value.

Cyclocross Bike Frame and Its Related Simple Introduction

Posted on by

What is cyclocross?

 

Cyclocross is a discipline that combines both off-road and on-road cycling. Typical cyclocross terrain includes grass, woodland trails, pavement, mud and even sand!

 

Rapidly growing in popularity, cyclocross racing is primarily an autumn/winter sport – with tens of thousands of fans attending races in Northern Europe. The attraction of cyclocross racing is the fast and frantic pace, around a lapped circuit of 2-3km in length.

 

The good news is, you can do cyclocross all year round! A cyclocross bike is incredibly versatile, and can make the perfect commuter, touring bike or do-everything ride.

 

What is unique about a cyclocross bike?

 

At first glance, a cyclocross bike can appear to look like a road bike; however there are many features that make them uniquely different and more suited to the specific purpose of multiple terrains riding.

 

These differences include the tires, frame design, brakes, gears and pedals. Below we only introduce the cyclocross bike frame designs.

 

Cyclocross bike frame design

 

The frame of a cyclocross bike has been adapted from a standard road bike frame, in a number of ways:

 

  • Increased tire clearances on the frame and fork – A cyclocross bike frame have increased clearance for tires on the front and rear of the frameset. This is so that you can use larger volume tires, for increased grip and traction; as well as allowing the wheels to keep turning, even when they are carrying significant quantities of mud or trail debris in the tire tread.

 

  • Frame geometry – Cyclocross bikes often have more relaxed geometry angles, to give them a more upright riding position than a road racing bike. This position helps with shock absorption off-road, but it also allows you to utilize the bike across multi-disciplines, such as touring and commuting.

 

  • Frame material – Many modern high-end road bikes are now made of carbon fiber, due to its light weight and vibration absorbing characteristics. Cyclocross bikes have followed this trend too, with many high end models made of carbon. However, aluminum and steel frames are also still popular; because they provide a lower cost option, and provide a more durable frame if the rider wants to use the bike for touring or commuting.

 

Frame sizing on cyclocross bikes

 

As with all bikes, the sizing of cyclocross bikes is vital to maximizing comfort and performance when you are riding. This is especially important if you are going to be using the bike for long distance touring or winter training as well.

 

 

What else can I use a cyclocross bike for?

 

Cyclocross bikes are not just reserved for use off-road. The relaxed geometry, strong frame, powerful braking and good tire clearance, mean a cyclo-cross bike is highly versatile machine. ‘Cross bikes can easily be used for other disciplines within the sport; such as commuting, winter training, cycle touring and off-road adventures.

 

When you are considering our range of cyclocross bikes, you may want to consider what other uses you may have for the bike; some bikes have mounts for pannier racks and mudguards, as well as more powerful disk brakes that are ideal for touring with heavy loads.

How Do I Choose the Best Lathe Tooling Holder?

Posted on by

When you are attempting to choose the best lathe tooling holder for any lathe, you must identify the type of lathe tools or bits that you want to use with the holder. The typical lathe tool holder is designed to fit a certain-sized tool or bit, so if you wish to find a holder to work with tools already in your possession, you will need to match the holder with the shank size of your tools. The type of dial and adjustment or feed regulator of the tool holder is also an area to be considered. The typical metal lathe is used to manufacture parts and tools that must adhere to critical measurements. You will typically want to choose a lathe tool holder that offers you the most precise and exacting adjustment and tool control.

 

The most common design for a metal lathe tool is for it to be attached onto the end of a piece of square steel stock. The square shank is placed inside of the clamping component of the lathe tool holder. Depending on the size of the lathe, the tool shank and the holder, the best lathe tooling holders could conceivably be found in several different sizes. You will want to match the holder to the size tools that you will want to use with your lathe. Smaller tools are less expensive as a rule, however, the smaller the tool, the less strength it typically has.

 

Once you have decided on the size of the tool that the lathe tool holder will be used with, the next critical decision will be to choose the type of control or adjustment dial that your new holder will incorporate. As a rule, the more finite and slow-moving the lathe tool holder adjuster is designed with, the more accurate and precise the adjuster. Similar to a micrometer, the very slow-moving adjustment mechanism allows for much more precision when making adjustments.

 

The better tooling holders will also have more adjustments designed into the tool holder. Less expensive and lower-quality holders will usually have only an in-and-out and back-and-forth adjustment available to the user. The best lathe tool holder designs, however, will also incorporate an up-and-down adjustment. This adjustment will allow the user to make cuts slightly off of center for a new dynamic when turning steel. It is also common for the best designed lathe tool holder to allow the user to place the tool holder in both a left side as well as a right side tool feed position.
