Hardinge launches quick-change collet range

A quick-change range of high accuracy, permanently bonded, sealed collet heads is available from Hardinge.

They have capacity options of up to 42 mm or 65 mm and features versions that will provide an accuracy within 0.010 mm TIR, while across the range have a wider than normal gripping capability of + 0.5 mm.

The precision-engineered Hardinge FlexCTM collet system can be exchanged within 20 secs and is industry compatible for mounting on lathes with A2-5, A2-6, A2-8 and 170 mm spindles.

The system is available in three styles: 'A' pull-back dead-length(R) and 'D' pull-back thru-hole, both with accuracies of 0.010 m, TIR; and 'DL' push-to-close dead-length(R), which has an accuracy of 0.20 mm TIR.

Collets are suitable for main- and sub-spindle applications and stock items include round-smooth, round-serrated and hexagon forms. Shapes such as square, stepped hole, off-centre and between size increments can be custom supplied.
