High Precision Grinding Sealed Air Chuck

Grinding Air Chuck

Grinding rotating chucks are hermetically sealed. They are designed to operate on CNC grinding machines and conventional as well. The design prevents penetration of any swarf or metal dust into the chuck, minimizing maintenance and stoppage time. Other applications are machining abrasive materials such as, powder metal or carbide. This chuck may be used on a turning machine as well.

Repeatability is 0.002MM or 0.0001".
Chuck size range from 87MM to 265MM or 3.5" up to 10".
