HIGH PRECISION COLLET, CLOSE TO SUBMICRON NEW BABY COLLET

HIGH PRECISION

The NBC collet is 100% inspected to guarantee accuracy. Material, production, heat treatment... everything is selected for precision.

ENSURES HIGH ACCURACY The double effect of precision threads finished after heat treatment and the smooth tightening of the thrust balls without torsion on the collet achieves stable high-precision collet tightening. Furthermore, the mechanism acts to prevent the thrust ball from jumping out due to centrifugal force generated by high speed rotation, promising stable machining.

COOLANT THROUGH TOOLS (BPS) The sealing functionality of the PERFECT SEAL means that the higher the coolant pressure is, the tighter the PS Ring adheres to the tool shank, increasing the sealing effect. The secure sealing function allows coolant to be securely supplied to the tip for high-pressure machining in high-speed applications. A sealing nut is used with a standard collet.

COOLANT METHODS TO SUIT THE APPLICATION BABY PERFECT SEAL A coolant nut with oil sealing functionality. Removing the internal PS Ring allows jet-through coolant supply.
