Dunham Tool manufactures a high quality
2j CNC collet chuck, 5c collet chuck, 16c collet chuck and
3j CNC collet chuck as well as many other sizes such as a
1c collet chuck and 3c collet chuck. These precision lathe
chucks will mount directly to American Standard (A4, A5, A6,
A8) and Camlock (D4, D5, D6, D8) style spindles. The Dunham
Tool lathe chucks are also frequently used on cylindrical
grinders, rotary tables, and many other machines. Dunham will
provide the correct spindle and draw tube adapters to accommodate
your spindle and draw tube requirements.
These productivity enhancing CNC collet
chuck systems have a built-in concentricity adjustment (under
0.00050” TIR) and can be mounted on all American Standard
spindles in less than 20 minutes. Only one complete lathe
chuck assembly is required because each spindle adapter of
the assembly will accept any Dunham Tool 16c, 2j, 3j and 5c
collet adapter. Change-over is accomplished quickly and easily
by the removal and replacement of only six bolts on the collet
adapter Also available for Camlock style spindles.
