CNC Collet Chucks, Modified Standard Collets for Unique Part Geometries

Zagar’s 22c CNC Collet Chuck and collet offer quick-change and secure holding of die cast parts for turning operations.

Zagar Inc. is increasing its design and engineering services for customers that would otherwise seek custom workholding for lathe operations. This includes its 22c CNC collet chucks and its standard collets that are modified to mate exactly with unique die cast part configurations. The parts can be held securely on either ID or OD surfaces, providing increased machining access.

One CNC collet chuck holds each modified collet. Working together with a draw-bar spindle and coupling with the back of the collet chuck, the clamp mechanism is actuated inside to securely locate and hold the part in a single step. The setup is designed to help ensure machining performance while providing very low runout as well as quick changeover to keep machine uptime high.

CNC collet chucks and collets are an alternative to pneumatic or hydraulic workholding devices and are well-suited for high production runs. Standard shapes such as round, square and hexes can be held accurately and quickly compared to a three or four jaw chuck.

Through its design and engineering, Zagar says it can help customers with virtually any special need. Often times the solution is simpler than customers would expect, with measurable reduction in man hours and increases in machine utilization, the company says.
