Tightening fixture for collet chucks with an integrated torque indicator

The aim of this new system is to help manufacturers achieve high-precision machining by notifying the user of a correctly set torque value via an audible buzzer. This tightening fixture was developed to replace multiple torque wrenches and comes with adapters for all common machine tool interfaces such as HSK, SK and BT. 

For maximum convenience, torque values of all the BIG KAISER-made collet chucks that are available from ITC are pre-set. The user can, however, set the torque to any value of their own choosing from 4 to 80Nm. The minimum read value is 0.01Nm at less than 10Nm, and 0.1Nm at 10Nm or more. The Torque Fit includes an error LED to indicate overtightening. 

Commenting upon the new device, VP Sales at BIG KAISER, Giampaolo Roccatello says: “High precision is vital for machining applications. The Torque Fit plays a relatively small yet essential role in ensuring that high precision is simple and quick to achieve in real world conditions. It is far more economical for the customer to purchase only a single Torque Fit instead of multiple torque wrenches."
