GRINDING AIR CHUCK, SEALED
High precision grinding air rotating chucks are sealed. The pneumatic chucks are designed to operate on CNC grinding machines and conventional as well. The air chuck 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.
Accuracy is 0.002mm or 0.0001".
Chuck size range from 87mm to 265mm or 3.5" up to 10".
The pneumatic grinding chuck comes in 2 and 3 jaws.
