Power chuck

Product Overview
Distortion-free workholding is achieved by a unique chuck design in which clamp fingers conform to a part’s natural, as-processed contour. Regulated clamping pressure and the resulting force dynamics provide rigidity to fragile and delicate parts, enabling secure clamping and accurate location without part deformity or distortion.

Features & Benefits

• Minimal distortion on workholding of fragile and delicate parts because of inherent force dynamics
• Higher attainable spindle speeds — less influenced by centrifugal forces that cause grip force loss
• Improved concentricity on secondary operations compared with a standard collet
• Higher productivity through fewer part rejects and potentially fewer re-chucking operations
• Easy replacement of clamp fingers due to individual mounting to the chuck body
• Variable adjustment of input actuation for fine tuning of clamping pressure

Applications

• Thin-walled parts where distortion is a concern
• Aluminum die cast components
• Automotive and aerospace components
