High Speed Balancing Chuck
Northfield Precision Instrument’s high speed balancing chuck locates a universal joint using built-in V-blocks and two diaphragm jaws. The jaws and blocks center the workpiece while two arms slide down to face clamp.
Northfield Precision announces the development of two methods of high/low chucking: “on the fly,” and “cycle interrupt. ” Using a proprietary valve system, delicate parts can be rough machined and finished in one chucking. The cycle starts with the jaws clamping at high pressure for roughing, then dropping down to low pressure for finishing.
Diaphragm Chucks Break A Bottleneck
Finding a better way to hold the part meant more parts per shift, better tool life and improve surface finish.
