FINGER CHUCK

Finger ChuckGMT – TWIST FINGER CHUCK

A finger chuck is good example of an axially gripping chuck. These chucks are known as finger chucks due to their finger-like pull back gripping of a part. It grips unusually shaped parts, where only an axial gripping force is possible. They find application for the high-speed machining of aluminum wheels.

GMT has developed a specialized finger chuck for second operations where radial clamping is not possible. The axial tension results in a distortion-free take up of the workpiece. In addition, this chuck has workpiece locator in order to ensure the exact location. A suitable locator locates the component center. Furthermore, the fingers located in a rod, which has a helical groove ensure that the component is flat against the chuck. Also, this enables loading yet ensures accurate location.

The chuck fingers swings in and clamps the component in a single motion as a result of hydraulic rotating cylinder actuation. Actuator pin is located on helical groove for actuating the finger chuck. Fingers during de-clamping lift and swings out for component unloading and loading. Consequently, the finger chuck firmly clamps the component without any distortion or surface damage.

SALIENT FEATURES:

  • Chuck has a locator for locating the component
  • Power Operated Twist finger chucks cannot perform without locating the component
  • Fingers are located in a rod, which has a helical groove
  • Actuator pin located on helical groove for actuating the finger. Fingers during clamping and de-clamping lift, swings in and out, for component loading and unloading
