> Torque fit: collected chuck tightened correctly by Big Kaiser

Germany, Hannover: ensured precision with tightening fixture, with an integrated torque indicator


Torque Fit: collected chuck tightened correctly. Tightening fixture for collet chucks with an integrated torque indicator presented by Big Kaiser at EMO 2017. Big Kaiser is a global producer in premium high-precision tooling systems and solutions for the metalworking industries.

The Torque Fit makes it easy to ensure that a collect chuck is tightened correctly, helping to 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.


Big Kaiser is an official technology partner of Suter Racing. At the EMO 2017 Big Kaiser presented at the visitors the Suter 500, the world’s fastest two-stroke motorbike.

Preset of torque values with error LED

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

High precision is vital for machining applications,” says Giampaolo Roccatello, VP Sales at Big Kaiser. “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.
