MEGA CHUCK SERIES

Precision ground and balanced
For high speed machining

MEGA CHUCKs are micro mirror ground finished on all surfaces to assure perfect concentricity for high speed machining. The drive keyway is machined after heat treatment. The MEGA CHUCKs are then balanced with a high precision dynamic balancing machine.

Drive keyways are ground after heat treatment.

Notch-free design mega nut prevents
Vibration and reduces noise

Vibration at high speeds is eliminated with the use of notch free designed nuts, which offer superior balance and concentricity.

Notches for wrench application

Collet chuck designed exclusively for endmilling
up to ø12mm with high concentricity & rigidity.
High grip collet
High grip collet

Gripping force is an important element for endmilling with a collet chuck. The long gripping length of the collet in the MEGA E series provides a powerful gripping force.
The shallower taper of the collet improves concentricity in order to achieve better surface finishes and longer cutting tool life.
