Product Description and Use:
The Hardinge FlexC style DL Collet System consists of a spindle mount assembly. Vulcanized collet heads and wrenches are
purchased separately. The style DL Dead-length
®
Collet System can be used as a thru-hole for bar work or with a work
stop for chucking. The clamping heads consist of hardened steel segments that are joined together by a vulcanization pro-
cess. Their outstanding characteristics include parallel workpiece clamping, superb accuracy with a minimum of deformation
of the work piece, and quick-change capability. If the Hardinge FlexC style DL Collet System is used as a dead-length system
the work stop is inserted into the workstop adapter with the part stop wrench included. When part length control is not
required the work stop can be removed.
The Hardinge FlexC style DL 65mm Collet Systems use a push-to-close design with an axially-fixed collet head. They are
ideally suited for sub-spindles to maintain length control during secondary operations. The push-to-close design also avoids
axial stress between the spindles. The collet head is fixed in the spindle mount, while the drawbar moves forward and
closes the collet head.
