DRAW-IN LONG NOSE COLLETS SW&B

Schlenker draw-in long nose collets SW&B are designed and manufactured to offer maximum precision and reliability.
By using them, you improve the processing quality and precision of your machines considerably.

USE OF DRAW-IN LONG NOSE COLLETS SW&B

Draw-in long nose collets are used for workpiece clamping as well as in all common grinding machines, dividing heads and manual turning machines. The long nose provides better accessibility to the workpiece.
Clamping is performed by retracting the draw-in collet into the collet sleeve.
