- Super Balancing

Balancing is another indispensable factor for high-speed cutting work. The over-all surface grinding from the V-flange's face to the holder's neck brings forth the chuck's high-balance capacity, enabling even the standard model to be used for a high rotation machining up to 25,000min^-1.

- Super Rigidity & Super Grip Force

Superior high rigidity is achieved by minimizing the collet's protrusion from the holder and also by increasing the wall thickness of the holder's collet insertion hole. This grip force is increased 1.5 times compared to that of YUKIWA's YCC collet, making it suitable even for the high-speed machining work on the end-mill.

- Safety

Usually, the steel balls in the lock-nut are screw plugged in order not to fall out. Our lock-nut has an additional safety cover made of steel, press-fitted on the outer circumference with its edges caulked in and thus, safely usable in high rotation work. The coolant seal screw allows a high-pressure coolant (spindle-through type), and the length adjustment bolt of APM types, ensures the high runout accuracy by preventing tool inclination.
