Collet Chuck
|
|
Collet chucks hold the workpiece or tool with a multi-finger collet. Typically, the collet fingers expand and retract together, and are self-centering. Collet chucks are used commonly for tool holding.
|
| |
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.
|
| |
Drill Chuck / Jacobs Chuck
|
|
Drill chucks are keyed or keyless chucks that are used primarily with drilling machines; however, they can also be used with other machining operations. Drill chucks are often called Jacobs chucks or Jacobs-style chucks, a reference to the company that standardized a popular, heavy-duty, drill chuck.
|
| |
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.
|
| |
Fixturing Chuck / Clamping Chuck
|
|
Fixturing chucks or clamping chucks are used to locate and hold fixtures, vises, pallets, and molds for automated, repeatable machining operations.
|
| |
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.
|
| |
Lathe Chuck
|
|
Lathe chucks are designed for use with lathes or turning centers. This category includes several types of jaw configurations.
|
| |
Magnetic Chuck
|
|
Magnetic chucks use the magnetic force from a permanent magnet or electromagnet to achieve chucking or holding action. They are only suitable for workpieces made of magnetic materials such as steel or iron.
|
| |
Milling Chuck
|
|
Milling chucks are designed to hold machine tools for milling operations. They have high rigidity and torque ratings, and prevent the accidental removal of tools.
|
| |
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 Chuck
|
|
Scroll 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.
|
| |
Speed Chuck
|
|
Speed chucks are designed for rapid tool or workpiece chucking and unchucking. They provide features such as a gripped handwheel around the chuck.
|
| |
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.
