Collet chucks
Notice
Tightening the union nut excessively without an inserted tool can compress and thus damage the collet
chuck.
➢
Tighten the union nut only when a tool is inserted.
➢
To protect the thread, screw the union nut only lightly onto the milling spindle when there is no tool
inserted.
Information for using the collet chucks:
-
Ensure that you use the correct cutter size for the collet chucks.
-
To prevent the collet chucks from binding, oil them a little at the beginning and after prolonged use.
-
To improve the concentricity, lightly grease the collet chucks or use a solid lubricant (for example Molykote
P-40).
-
Using a square piece of wood or a rubber mallet (never a metal tool!), tap lightly from behind on the collet
chuck to loosen it if it is jammed.
Use the following procedure to mount a collet
chuck:
1.
Click the collet chuck into the union nut.
2.
Screw the union nut onto the milling spindle.
