Type
   Type       
   Your choices are...         
   Collet Chuck       Collet chuck holders use collapsible spring collets of various types and sizes to hold workpieces of different shank sizes with one chuck. The collet is secured in the collet chuck with a collet nut, tightened to the manufacturer's specifications. 
   Core Chuck / Roll Chuck       Core chucks or roll chucks have jaws which expand outward to grip the inner diameter (ID) of a roll or tube. They are used in web processing, paper roll winding, unwinding, and dispensing; label roll processing and dispensing; and other applications where webs, sheets, or fabric are rolled or unrolled. Core chucks and roll chucks often use automatic gripping that is proportional to speed or torque. 
   Diaphragm Chuck       Diaphragm chucks mount the top jaws on a steel membrane or diaphragm. Typically, these top jaws are custom-fabricated for specific workholding applications. Applying hydraulic or pneumatic pressure to the inside of the diaphragm (either directly or with a cylinder) causes the membrane to bulge outward and expand the jaws. After the workpiece is loaded, the pressure is released, causing the top jaws to retract, close, and clamp the workpiece.  Diaphragm chucks are often used with thin-walled or fragile workpieces that can be deformed by the pressure of power chucks or other chuck configurations. Diaphragm chucks feature a simple design for loading and unloading, and provide high repeatability. 
   Draw Bar Chuck / Pull Down Chuck       With draw bar chucks and pull down chucks, the radial movement of the jaws is affected by axial actuation against a fixed, tapered surface. 
   Electrostatic Chuck       Electrostatic wafer chucks are used with sophisticated semiconductor-manufacturing equipment. They hold a very thin disc in a high-vacuum chamber while contacting only one side of the disc. Electrostatic chucks are made primarily of a ferroelectric alumina ceramic material. 
   Gear Chuck       Gear chucks are designed to hold gears during machining operations. Chucking can be done on the major or minor diameter of the gear, but is often done on the pitch circle of the gear for feature concentricity with the gear pitch. Different chuck inserts are used to chuck different pitches. This category includes chucks for gripping straight, helical, bevel, and other gear-tooth configurations. 
   Grinding Chuck       Grinding chucks used in grinding equipment. They typically have high accuracy and concentricity specifications, as well as good rigidity for tight-tolerance grinding operations. 
   Safety Chuck       Safety chucks have special guards and safety features to prevent finger damage or other operator injury. They are often used with reel or roll winding and unwinding equipment. Typically, safety chucks are used in pairs. One side is motorized and the other is used as an idler. Foot and flange mounting styles are common. 
   Scroll / Power Chuck       Scroll and power chucks have jaws that move together, in and out radially. Teeth on the back side engage a raised, spiral set of teeth on the face plate. Most scroll chucks require manual adjustment, often with a specialized wrench or key. 
   Universal Chuck       Universal chucks have jaws that move together, toward or away from the center (i.e., self-centering, concentric). The term "universal" is sometimes used to describe chucks that can clamp both the OD and ID of a workpiece, either with a special jaw construction or by flipping the jaws around. 
   Vacuum Chuck       Vacuum chucks apply a vacuum to the back of the workpiece to achieve chucking or holding action. The vacuum is supplied by an electric vacuum pump, or a Venturi vacuum generator powered by compressed air. Vacuum chucks are relatively easy to use and minimize or eliminate marking of the workpiece. Applications range from simple, traditional uses such as wood lathes to very high-precision work such as semiconductor wafer processing.  Vacuum chucks are available in a wide range of shapes and sizes.

Chuck Features & Materials
           
   Your choices are...         
   OD Clamping       The chuck is designed to clamp onto the outer diameter (OD) of the workpiece or tool. OD clamping is common with machining chucks used in applications such as milling, drilling, or turning. 
   ID Clamping       The chuck is designed to clamp onto the inner diameter (ID) of the workpiece or tool. ID clamping is common in applications such as machining and grinding, and is used to process workpieces such as pipes or internal gears. 
   Brake       The chuck has an integral brake that can quickly slow or stop the chuck's rotation. 
   Compensating Chuck       Compensating chucks maintain the workpiece position when the jaw is opened or closed. 
   Independent Jaws       The chuck's jaws may be adjusted, tightened, or centered one-at-a-time, and without affecting the position or adjustment of the other jaws. 
   Interchangeable Jaws / Inserts       The chuck's design facilitates the replacement of jaws or jaw inserts. Applications for interchangeable jaws include: using different jaw sets with different chucking sizes; replacing hardened jaws or inserts with soft, non-marring inserts; and using different jaw lengths for different workpiece configurations. 
   Keyless       The chuck's design permits simple, manual chuck adjustments (e.g., tightening) without the use of special tools such as a wrench or chuck key. 
   Locking       The chuck's jaws can be locked or set to provide holding force, even when the actuation mechanism (e.g., hydraulic or pneumatic pressure) is removed. 
   Machinable Jaws / Inserts       The chuck's jaws or inserts can be machined for custom workholding applications. 
   Quick Change       The chuck or chuck jaws can be removed rapidly from the machine or test fixture, and quickly replaced with another chuck or set of jaws. 
   Quick Release       The chuck permits the rapid release or disengagement of chucking force. Quick-release chucks are used for rapid, automated tool or workpiece changing. 
   Rectangular / Square Workholding       Chucks are designed to hold square, rectangular, or other non-round workpieces such as rectangular tubes, angles, channels, square stock, etc. 
   Retracting Jaws       The chuck's jaws can retract during operation. Chucks with retracting jaws often incorporate auxiliary drive mechanisms such as pins, vanes, or a face driver for maintenance of constant-drive torque. With lathes, retracting jaws allow for part-turning farther up the workpiece. 
   Self-Centering       All of the chuck's jaws contract and expand together, so that the workpiece or tool is center-chucked automatically at any jaw diameter. 
   Soft Jaws / Protective Covers       The chuck's jaws have a soft or protective surface to avoid marring the workpiece. These devices are also used to chuck or clamp soft materials or fragile shapes without deformation. 
   Through-Hole       The chuck has a center through-hole for chucking or gripping long sections of stock, pipe, etc. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Materials of Construction:       
   Your choices are...         
   Aluminum       Chucks are made of aluminum, a relatively soft, lightweight, non-magnetic, corrosion-resistant material. Aluminum chucks are used to avoid marring workpieces made of harder metals such as iron or steel. 
   Brass / Bronze       Chucks are made of or lined with brass or bronze. Brass chucks and bronze chucks can avoid workpiece marring while still providing suitably rigid and precise holding and positioning. 
   Cast Iron       Chucks are made of cast iron, a common, rugged machine-tool material which provides some shock and vibration absorption. Cast iron is a natural composite whose primary constituent is iron, with trace amounts of carbon and/or silicon. 
   Ceramic       Chucks are made of ceramics, materials produced by the high- temperature fusion of minerals in a controlled environment that is designed to impart specific physical and electrical characteristics. Generally, ceramics are electrical insulators or semiconductors, and feature high resistance to thermal breakdown, erosion, and surface degradation (e.g., marring or pitting). Ceramic chucks are used in highly specialized applications such as semiconductor wafer-holding during processing. 
   Plastic       Plastic chucks are very soft. They are used to prevent marring or damage to the workpiece, and in applications which require materials with good electrical or thermal insulation. 
   Stainless Steel       Stainless steel chucks are made of specific, corrosion-resistant grades of steel. Typically, these metals are either non-magnetic or less magnetic than standard alloy steels. Stainless steel is less suited to hardening and certain types of surface finishing. 
   Steel       Steel chucks are made of carbon or alloy steels, tool steels, or hardened steels. Steel is a common chuck material. 
   Other       Other unlisted, specialized, or proprietary chuck materials. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
