Mega ER Grip: High Quaility Tool Holders

Mega ER Grip


Introducing the Mega ER Grip! The total precision of our collet, nut, and body shatter the common standard of ER collet chucks. BIG's Mega ER Grip is a high quality ER collet chuck that completely satisfies the 4 requirements for tool holders; clamping force, concentricity, rigidity, and balance for high spindle speeds.

Each part of the assembly puts together our high precision production technology and our design creativity for collets, clamping nuts and chuck bodies. When an inexpensive tool holder is selected based on a small cost saving, a waste in valuable time and money during production results in higher costs in the long term.

High rigidity body that increases
the contact area of the collet
 
ER GRIP Clamping

By increasing the contact length of the internal taper of chuck bodies, the undesired overhang of the collet is reduced. This modification of the standard improves 3 of the most important requirements for the collet chuck (rigidity, runout accuracy, clamping force). (Conventional DIN collets can also be used.)

High precision pre-balanced body

The unbalance of the drive keys in the steep taper and HSK tool shanks is reduced to a minimum by a pre-balancing operation. (BIG CAPTO tool shanks are also pre-balanced) The tool shanks also include tapped holes around the periphery so that precision balancing can be performed with balancing screws.

Simplification of the nut tightening operation with the Mega Wrench

The one-way clutch of the Mega Wrench tightens the nut firmly and securely by applying even torque to the outside periphery of nut.
The ratchet function greatly helps to simplify and speed up the tightening operation of the nut and prevents injury to the hands of the operator.
