The Advantages of Shrink Fit Chuck

Posted on by

If you do high speed, or high torque machining you should seriously consider the benefits of shrink fit technology.

 

Heat shrink tooling is considered one of the best methods for high-performance machining. The mold and die industry was the first segment of the manufacturing market to look for more precise tool holder options, due to the need for a slim nose and long reach. Today, every segment of manufacturing can benefit from the advantages of shrink fit tooling.

 

In this article, I’m going to show you the basic introduction to shrink fit chuck.

 

Tool holder Selection

 

When looking for tool holder solutions for any type of machining, it is always good to focus on the three main features that a tool holder must bring you:

 

  1. Rigidity

Rigidity comes from sufficient taper contact and proper clamping of the tool holder in the machine tool spindle.

 

  1. Accuracy

Accuracy comes from minimal run-out at the cutting edge of the cutting tool when clamped in the holder.

 

  1. Balance

Balance comes from a balanced assembly of the tool holder (including all accessories such as pull-studs) and cutting tool combination.

 

You may also often think about the following:

 

  • Geometry of Tool Holder

Geometry is important to avoid collisions with the workpiece. In regards to the EDM process, electrodes must be machined accurately and efficiently. Oftentimes, deep ribs are required in the part process and may present challenges. Also, deep cavities such as large door panel or bumper molds require deep reach with extreme clearances.

 

  • Cleanliness of The Tool Holder

Cleanliness is required to avoid excessive run-out, especially when machining graphite.

 

  • Extending Cutting Tool Life

Since high-end cutting tools are needed to obtain the best performance in the shortest time possible, a tool holder that extends cutting tool life can be advantageous. These cutting tools often have exotic coatings that lend to an expensive price.

 

  • Surface Finish at Higher Speeds and Feeds

Some tool holders are used with lower depth-of-cuts, which translates into better surface finishes. This makes balance even more important to minimize vibration at the cutting edge of the cutting tool. Also, proper chip evacuation provides better finishes.

 

Advantages of Shrink Fit Chuck

 

There are 10 inherent benefits that a good shrink fit chuck can offer:

 

  1. Unsurpassed Accuracy

A properly produced shrink fit chuck should be able to guarantee 0.00012’’ (3 microns) maximum run-out at three times the cutting tool diameter.

 

  1. Availability of Slim Profiles

Shrink fit chucks are available with three-degree draft angles and very slim profiles. They can also be modified to be straight walled, if needed, in order to prevent tool holder collision with the workpiece.

 

  1. Gripping Torque

A shrink fit chuck grips the cutting tool 360 degrees around the shank. This leads to a very high gripping torque that prevents the cutting tool from moving during roughing or finishing operations.

 

  1. Extended Reach Options

Shrink fit chucks can use shrink fit extensions that provide the user with many options with standard products. When machining deep cavities, one can place shrink fit extensions into standard shrink fit chucks, getting unsurpassed tool holder lengths with very little run-out.

 

  1. Balance Repeatability and Balanceable Options

Shrink fit chucks can offer some of the best balance repeatability of any tool holding system on the market, since there are no moving parts. In many cases, if a shop purchases a properly balanced shrink fit chuck with correct accessories (such as pull-studs) and uses good cutting tools without inherent unbalance (such as flats or unequal spacing), then they can often have good balance characteristics for running at high speeds without doing an additional fine-tune balancing.

 

  1. Reduction of Tool Changing Time and Less Tool Holder Accessory Inventory

Nothing beats the tool change time of shrink fit chucks if the process is joined with a capable inductive shrink fit machine. Tool changes can be done in 5 to 10 seconds, and most importantly, consistently. This allows the tool holder assembly to be in the machine making chips more of the time, rather than out of the machine waiting to be changed. Also, a shop needs very little additional tool holder accessory inventory (i.e., collets, nuts, seal disks, etc.). This simplifies the process.

 

  1. Cleanliness of Setup

A shrink fit chuck typically is a sealed system by design. Therefore, the introduction of contaminants in the bore is minimized. If contaminants are introduced to the bore of a tool holder, oftentimes run-out accuracy is compromised.

 

  1. Coolant Options

Shrink fit chucks have convenient methods to deliver coolant down to the cutting edge of the cutting tool. This helps with the proper removal of chips and can also aid in providing better finishes.

 

  1. Consistency of Setup

Shrink fit holders provide the great repeatability from tool holder setup to tool holder setup. This is especially beneficial for those shops running lights out. For example, all tool holder setup operators set the tool holders the same with shrink fit holders. There are no variables—such as over-tightening or under-tightening a collet nut or not cleaning out a chuck sufficiently.

 

  1. Availability of Shrink Chucks

Most of the major tool holder builders in the world now offer shrink fit chucks as a standard.

How to Choose a Suitable Wetsuit

Posted on by

Unless you are fortunate enough to live in the tropics, you know how important a wetsuit is to your comfort and health when surfing in the chilly waters of the open ocean. There is a wide array of wetsuit types to choose from, as well a range of material thicknesses, allowing you to customize your gear to the water and weather conditions wherever you may be.

 

Types of Wetsuit

 

  • FULL SUIT:

This suit envelops your entire body, usually with long sleeves (some have short sleeves) and full leg coverage.

 

  • SPRING SUIT / SHORTY:

With legs that cut off a few inches below the knee, and either short or long-sleeved arms, this suit is designed for warmer conditions and is usually made of a thinner material.

 

  • FARMER JOHNS:

The overall of the surfing world, this suit is sleeveless with long legs, designed for use with a rash guard on days when the outside air is warm.

 

  • SHORT JOHNS:

This suit is a shorter version of the Farmer John, with the same sleeveless construction but the cooler feel of cut-off legs.

 

  • MIX-AND-MATCH PIECES:

Neoprene vests, jackets and shorts, all made with the same construction as a typical wetsuit, fall into this category. These pieces allow customization based on the weather and temperature, both in and out of the water.

 

Wetsuit Materials

 

  • NEOPRENE

The idea behind a wetsuit is to permit a small about of water to seep into the suit initially, which, once heated by your body, forms an insulating layer of warmth. Foam neoprene, treated with water-repellant chemicals, prevents the cold ocean water from continuing to wash in and disturb the temperature within the suit.

 

The thickness of the suit determines how warm the surfer will remain after time spent submerged in the frigid water; the fatter the material, the warmer he’ll be. Neoprene panels come in several thicknesses: usually between 1-6 millimeters. Depending on the water temp, neoprene wetsuits are usually pieced together using different thicknesses of neoprene, heavier on the chest and back areas, and thinner on the arms, legs and shoulders. This multi-thickness construction leads to nominal classifications such as 3/2mm (3mm on the core and 2mm on the extremities, in this case).

 

  • BACKING MATERIALS

Because of neoprene’s rigid and grippy nature, it can be really tough to yank on a wetsuit and pull it up into place. Luckily, suit manufacturers figured out a way to lessen the resistance formed between the wetsuit and the rider’s skin. Smooth skin nylon facing is attached to the inside of the wetsuit, making getting in and out much easier, as well as providing added warmth to the surfer. Sometimes, the material is attached to both the inside and outside of the suit – a material construction known as Nylon 2 – which increases warmth, but also makes the suit more bulky. Smooth skin was a needed advance in wetsuit construction; however the added bulk coupled with a decreased durability in nylon-backed suits are the unfortunate side effects of such a progression. Manufacturers have now begun using lycra, spandex and even wool blends as a replacement for raw nylon backing, leading to wetsuits with much more flex and stretch, and a more streamlined fit.

 

Fit of Wetsuit

 

The fit of a wetsuit is not only important for comfort’s sake but also to ensure that the suit is properly insulating the wearer. Basically, the pocket of extra space between the suit and the surfer’s skin is designed to trap and heat a layer of ocean water to provide a cocoon of warmth. If a wetsuit is too baggy, the water won’t heat up enough; if it’s too tight, there won’t be enough water to heat. Either way, a proper fit is the only way to get the most out of a wetsuit.

 

The way that the neoprene material flexes and moves is also a significant aspect of a suit’s fit. To surf in comfort, you need to have a wide range of motion through the shoulders and knees to help you paddle and pop up with fluid motions.

Tips to Help with Choosing the Right Valve for Your Project

Posted on by

Valves are useful pieces of equipment that help control, limit, and shut off flow in a system. In a garden irrigation system, you could use valves to control when different plants get watered. While it is universally agreed that valves are helpful, choosing the right valve can be frustrating. We hear many customers make statements like these: “So many types exist! Some of them do similar things! I don’t know what types of valves to use!”

 

In this article, we will outline what makes each unique valve. For basic users, the most important thing to remember is that a valve does one of two things: shut off or regulate. Some valves can do either/both, but this is a simple way to think of what you need a valve to do. It could help you in picking the right valve. We will now cover each of the major valve categories.

 

Ball Valves

Ball valves are a good example of a shut off valve. They use a spherical seating to stop or allow flow. The ball has a hole through the center, so fluid can pass through when the handle is turned to the “on” position. When the handle is turned 90 degrees to the “off” position, fluid hits the solid side of the ball and is stopped.

 

Butterfly Valves

Butterfly valves can function as a shut off valve or as a regulatory valve. They can fully shut off flow or be kept partially open, which limits flow. Controlling flow can be extremely helpful if you want to decrease pressure in a system. Fluid passing through a small opening will be restricted, making pressure further down the pipeline lower, depending on how far open the valve is. Butterfly valves can also be used as typical 90-degree turn valves, just switching between “on” and “off” positions.

 

Gate Valves

Gate valves, while usually used as shut off valves, can also function as regulatory valves. They use a “gate” that drops or lifts to control flow. When the valve is open, the gate is stored in the tall upper section of the valve, which is where gate valves get their unique shape. Unlike the previous two valves, gate valves are not a quarter-turn valve. They use a hand wheel to open/close whereas ball and butterfly valves use a lever handle. This makes it easy to keep them partially open and also makes operation of any kind easier.

 

Check Valves

Check valves come in many forms. The primary function of check valves is to prevent backflow. This makes them regulatory valves, as they control flow direction. Check valves are controlled by the fluid in the pipeline instead an operator, which makes them different from the valves we have previously examined. Check valves come in many different forms, but we will just cover the two most common types.

 

Swing check valves are a type of valve that uses a swinging function to prevent backflow in a system. The clear PVC swing check valve to the right has a disc that swings open if fluid is passing through the desired direction. If anything tries to flow backwards, the disc is pushed closed, stopping flow. Swing check valves create minimal pressure drop, as the disc is pushed completely out of the way when in operation.

 

The other major type of check valve is the ball check valve. Ball check valves use a ball or half-ball seating to eliminate backflow. When fluid passes the desired direction, it hits the rounded side and passes around and through. If fluid tries to flow backwards, it hits the concave side of the half-ball, pushing the valve shut. Due to the fact that fluid must flow around and behind the ball to get through, ball check valves produce moderate pressure drop.

 

Diaphragm Valves

Diaphragm valves, while not one of the most common types of valves, are very interesting and serve a specific purpose. They are perfect for limiting pressure in a system, making them regulatory valves. These valves have a flexible diaphragm that lowers toward or rises from a “weir” or “saddle” seating. The effect is that only a limited amount of fluid is allowed to pass through.

 

Choosing the Right Valve

In the end, picking the right valve depends on what you need it to do. No two jobs are the same, so there is no one-size-fits-all valve solution. However, you should now have all the information you need to make an informed decision.

 

NICO VALVES CORP. is a leading industrial valve manufacturer in Taiwan and China. The company offers various valves such as check valve, ball valve, threaded end valve, wafer check valve etc. If you have any questions, try to check out NICO’s website and feel free to send inquiry to them.

Gear Rack and Pinion in Straight Cut and Helical

Posted on by

Tell you some information about precision rack and pinion in this article.

 

Rack and Pinion

 

Rack and Pinion assemblies are utilized to convert rotating movement into linear motion. A gear rack has straight teeth cut into one surface of a square or round section rod with a pinion, which is a small cylindrical gear meshing with the gear rack.

 

There are applications where the gear rack is stationary, while the pinion traverses and others where the pinion rotates on a fixed axis while the gear rack moves. The former is used widely in conveying systems while the latter can be used in extrusion systems and lifting/lowering applications.

 

As a mechanical element to transfer rotary into linear motion, gear racks are often compared to ball screws. There are pros and cons. The advantages of a gear rack are its mechanical simplicity, large load carrying capacity, no limit to the length, etc. One disadvantage though is the backlash. The advantage of a ball screw is the high precision and lower backlash while the shortcomings include the limit in length due to deflection.

 

Types of Gear Rack

Rack and pinion gears are available in two variations:

 

Straight teeth have the tooth axis parallel to the axis of rotation. Straight teeth that run parallel to the axis of the gear.

 

Helical teeth gears provide continuous engagement along the tooth length and are often quieter and more efficient than straight tooth gears and also offer higher loading for same rack width. Helical tooth gears resemble spur gears in the plane of rotation, but include teeth that are twisted along a helical path in the axial direction.

 

Applications of Rack and Pinion

 

Rack and Pinion drives are perfect for a wide range of applications, including axis drives requiring precise positioning & repeatability, travelling gantries & columns, pick & place robots, CNC routers and material handling systems. Heavy load capacities and duty cycles can also be easily handled with these drives. Industries served include Material Handling, Automation, Automotive, Aerospace, Machine Tool and Robotics.

 

JIA CHENG Precision Machinery Co., Ltd. reducer is a worldwide well-known brand. This company also provides high quality couplings, gear row, precision rack, and much more products for customers. If you need more information about planetary reducers and precision racks, try to check out Jia Cheng’s website to obtain further details you need.

Ceramic Capacitors and Reliable Capacitors Manufacturer

Posted on by

The ceramic capacitor is available in many versions including leaded disc ceramic capacitors, surface mount multilayer ceramic capacitors, MLCCs etc.

 

Ceramic capacitors are one of the most widely used forms of capacitor used in electronics equipment these days.

 

Ceramic capacitors have also been used for many years, being found in valve or tube circuits dating from the 1930s.

 

Today ceramic capacitors area available in a variety of formats ranging from leaded components to surface mount technology, SMT varieties. As leaded versions disc ceramic capacitors are widely available, and as SMT devices, multilayer ceramic capacitors or MLCCs are available in all the common formats. As such these ceramic capacitors are used in virtually every type of electronics equipment.

 

The actual performance of the ceramic capacitors is highly dependent upon the dielectric used. Using modern dielectrics, very high values are available, but it is also necessary to check parameters such as the temperature coefficient and tolerance. Different levels of performance are often governed by the dielectric used, and therefore it is necessary to choose the type of dielectric in the ceramic capacitor.

 

Ceramic capacitors range in value from figures as low as a few Pico farads to around 0.1 microfarads. In view of the wide range and suitability for RF applications they are used for coupling and decoupling applications in particular. Here they are by far the most commonly used type being cheap and reliable and the loss factor is particularly low although this is dependent on the exact dielectric in use.

 

Basics of Ceramic Capacitor

Ceramic capacitors are the workhorses of the capacitor world these days. Ceramic capacitors are used in millions as a result of a combination of their cost and performance. There is a wide variety of dielectrics that can be used as described below, but as the name of the ceramic capacitor suggests, they are all ceramic in nature.

 

In order to ensure that sufficient levels of capacitance can be obtained within a single capacitor package, ceramic capacitors, like types of capacitor have multiple layers. This increases the level of capacitance to enable the required values of capacitance to be achieved.

 

Ceramic capacitors are available now in three main types although other styles are available:

 

  • Leaded disc ceramic capacitors for through hole mounting which are resin coated
  • Surface mount multilayer ceramic capacitors
  • Specialist microwave bare leadless disc ceramic capacitors that are designed to sit in a slot in the PCB and are soldered in place

 

Although it is possible to obtain other types of ceramic capacitor, these are the main types that can be found today. Of these the surface mount variety is used in the greatest quantities by far because of the manufacturing methods used these days for electronic equipment.

 

Capacitors Supplying Expert

Zonkas Electronic specializes in manufacture of Ceramic Capacitors which are applied to various industries. The ceramic capacitor is a capacitor constructed of alternating layers of metal and ceramic, with the ceramic material acting as the dielectric. The company has well-equipped manufacturing facilities that are operated by a team of experts.

6 Major Furnace Controls

Posted on by

Gas furnaces are the most popular type of furnace installed in residential homes. They are equipped with many controls to make sure safe and efficient operation. It is important to check the furnace specifications and manuals to properly understand how the controls work. Here are five major furnace controls found on a residential gas furnace.

 

Gas Pressure Regulator

 

Because the gas from the main line is subject to different pressures, a gas pressure regulator ensures a consistent gas pressure into the burner manifold. This is usually located in between the supply tank and the main gas valve. This ensures your furnace receives the right amount of gas to burn; not too weak and not too much.

 

Main Gas Valve

 

Just like a gas pressure regulator is needed so is a main gas valve. Its main function is to control the flow of gas from the outside supply line or storage tank to the gas burner. They come in many different shapes and sizes and usually located behind the front panel of the furnace. The gas valves will include a safety shutoff valve that allows you to turn off the main gas line and the pilot gas. In a modern furnace that does not have a standing-pilot light, these main gas valves are called electronic ignition gas valves.

 

Mercury Flame Sensor

 

You will find a mercury flame sensor in a newer furnace with an electronic ignition system. It is made up of a mercury-filled sense end, a capillary tube and an SPDT switch assembly. The sensor end is filled with mercury and heats up from the direct burner flame. When heated, the mercury liquid triggers the switch and opens the gas valve.

 

Thermostat

 

A room thermostat is the main control of when a furnace operates based on the temperature of the room. A thermostat senses changes in air temperature that is being heated and send an electrical signal to open or close the automatic gas valve of your furnace. Most thermostats are wired with the pilot safety valve, limit control and the automatic main gas valve.

 

Thermocouple

 

A thermocouple is the safety device used to detect whether the pilot light is is lit before the main gas valve is opened to supply gas to the burners. A Thermocouple uses a heat-sensing device that senses the heat from the pilot light and then converts it into an electric current allowing gas into your furnace to ignite.

 

Thermopile

 

Sometimes called a thermopile generator or millivolt generator, a thermopile is another safety device for the main gas line and pilot light. Just like a thermocouple, the heat-sensing device is used to detect the pilot light is on. A thermopile is larger and delivers more electricity than a thermocouple. The advantage of a thermopile is it does not require a transformer.

 

Established in 1989, Alpha Brass Controls operates under ISO 9001:2008 and its laboratory cooperates with CSA and CE testing bodies to manufacture commercial gas valves and provides solutions of thermostat, safety valves, and various gas valves for professional cooking industry.

Basic Information of Tool Holders and Static Tool Holders

Posted on by

Tool holders (toolholders) are the physical interface between tooling and the machine tool. They come in a multiple of different machine mount styles from the older R8 style to newer HSK or VDI mount.

 

Tool holders have three main parts: the taper, the flange, and the collet pocket. Driven or “live” tooling is powered, while static tool holder is not.

 

  • The taper is the conically-shaped area of the tool holder that enters the spindle during tool changing.
  • The flange is the part of the tool holder to which the automatic tool changer is attached when the tool holder is moved from the tool changer to the spindle.
  • The collet pocket is the area into which the collet is inserted before being secured by various types of collet nuts.

 

Some tool holders shrink-fit around the machine tool or cutting tool and remain firmly in place. Others are optimized to the smallest size possible to allow for maximum clearances during machining.

 

Tool Holder Types

Industrial buyers can find these types of tool holders at some manufacturers:

 

  • Machine arbors are motor-driven shafts that turn machine tools.
  • Blank adapters can be customized for specific applications or machining tasks.
  • Boring heads can hold a variety of cutting tools, but are used mainly with boring bars.
  • Collet chucks use collets of various sizes to hold machine tools.
  • End mill holders are designed to holdend mills during milling operations.
  • Milling or drilling chucks are used to hold various cutting tools during milling or drilling applications.
  • Outer diameter (OD) and inner diameter (ID) tool holders can hold a variety of cutting tools.
  • Shell or face mill adaptors are designed to hold shell or face mills, tools used to cut surfaces.
  • Side cutter holders are designed to hold side cutter tools.
  • Saw blade holders are designed to hold saw blades.
  • Tapping chucks are designed to hold tapping tools for threading operations.

 

Mounting Styles

When selecting tool holders, buyers need to specify a mounting style.

 

  • R8 is used by a majority of Bridgeport machines manufactured after 1965; however, this taper is seldom used with today’s high speed machining (HSM) equipment.

 

  • Morse taper (MT) is available in four common sizes: #1, #2, #3, and #4. Each size has a tapered fit for fast changes.

 

  • National Machine Tool Builders (NMTB) defined the NMTB taper for all CNC milling machines. The standard is 3.5 in. per ft. and can require a drawbar.

 

  • Caterpillar®developed the CAT® mounting style, sometimes called the V-flange, to standardize the tooling for its machines. Designations such as CAT-40, CAT-50 and CAT-60 refer to the NMTB taper size. (Caterpillar and CAT are registered trademarks of Caterpillar, Inc.)

 

  • BT is similar to CAT, but is balanced and symmetrical around the axis of rotation. BT uses the same NMTB body-taper measurement notations but uses a metric pull-stud thread.

 

  • Hollow shank tooling (HSK) is designed to increase grip as spindle speed increases. It does not have a pull stud and is often used with HSM. VDI is designed for quick-change tooling and is available in both dovetail and straight-shank versions.

 

  • Tool holders that use base mount tooling (BMT) and straight shank tooling are also available.

 

Tool Holder Sizes

The projection length of the tool holder is the distance from the gage line (the reference mounting surface) to the end of the tool holder. If specifying a collet pocket is applicable, buyers can choose an ER or TG type.

 

Features and Applications

Tool holders can be coolant-fed or have a coolant-thru flange. Some are optimized to the smallest size possible to allow for maximum clearances during machining. Each tool holder is designed for a specific application and tailored to optimize both machine performance and operational efficiency.

 

Tool Holder Manufacturer

Where to find the excellent tool holder manufacturer? I will say Shin-Yain Industrial Co., Ltd. is the recommendable static tool holder manufacturer. The company is specializing in numerous tool holders, like collet holder, static tool holder, CAT tool holder, BT tool holder etc. all can be found. If you have any interest, try to check out SYIC’s website and send inquiry to them.
