Chucks

Lexair’s full-bore, fixed-length, self-contained collet chuck allows full-capacity spindle operation, due to elimination of the drawtube. When using the full bore chuck, spindle capacity is boosted as much as 30 percent, and clamping pressure is unaffected by centrifugal force, regardless of rpm, according to the company.

Northfield Precision Instrument Corp. reported that when a customer requiring a highly specialized diaphragm chuck was not finding success with other chuck manufacturers, they turned to Northfield Precision Instrument. The chuck needed to be submersible for use in a wire EDM. To achieve this, the engineers at Northfield designed a specialized chuck with all non-stainless steel wetted parts.

Collet pad top jaw systems from Dillon Manufacturing Inc. can convert through-hole chucks to hold small bar and tube stock. Collet pads can be changed quickly maximizing production time, and the jaws can be adapted to many styles of chucks, making them ideal for special purpose function machining.
