Ideal for Precision Turning and Cylindrical Grinding Operations

The gripping force utilizes the spring-back reaction of the diaphragm, providing an elastic repeatability accuracy of 0.002 mm T.I.R.

Its non-sliding design minimizes wear and reduces problems caused by chips and grinding dust, ensuring long-term high-precision gripping performance.

The standard specification incorporates a built-in pneumatic cylinder for simple and easy piping.

For OD gripping, the pull-back function operates effectively, providing excellent parallelism between the axial dimension and the reference end face.

The jaws are heat-treated to a high hardness and precision-ground, allowing easy replacement while maintaining high accuracy.

Diaphragm Chuck with High-Precision Elastic Recovery

The diaphragm provides highly accurate elastic recovery and is resistant to accuracy degradation caused by wear or the intrusion of grinding debris. As a result, diaphragm chucks are widely used for precision finishing operations.

Our diaphragm chucks are commonly used for finish turning and grinding applications, including scroll machining for scroll compressors and the machining of gear chuck bodies referenced from the pitch line.
