BIG KAISER offers the new Torque Fit, a tightening fixture for collet chucks with an integrated torque indicator.
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.
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.
