Setting Up Collet Blocks for Multiple-Part Machining
Collet blocks can be used horizontally or vertically on
mill tables, jig grinders, fat or angled fxture plates,
tombstones or rotary trunnions. Group them together
hydraulically or pneumatically for high-production, multipart machining. Part gripping sizes range from 0.008"
(1C collet) up to 6" (step chuck) in diameter. Hex, square
and custom-shaped collets are available to hold a variety
of shapes. Hardinge ofers several models of collet blocks
that use standard collets — 1C, 3C, 5C, 16C, 3J, 22J,
35J, and FlexC 42 and 65 mm.
The part diameter or range of parts will dictate the
collet size required. The part size and the machining process will determine the required gripping force.
Higher gripping forces will be needed for heavy rotation,
tapping, threading or of-center work. Hardinge will help
determine what size collet block is needed, whether a
high-force or low-force collet block is needed, and if a
hydraulic or pneumatic operation is needed.
