4.3.1 Recommended tightening torques (consider overall system)
- Tightening torque for union nut / collet chuck = 10 - 11 Nm
- Tightening torque for collar = 7 Nm
The collar (4) has a diameter of 43 mm [1.69 in] and
is 25.5 mm [1 in] wide.
The clamping unit in which the milling motor is
installed must be at least 20 mm [0.79 in] thick.
If possible, clamp the milling motor over the entire
mounting diameter of the clamping neck (4).
If possible, avoid spot clamping (e.g. via a threaded
pin) in the clamping neck (4). Excessive clamping
force can damage the internal ball bearings.
4.3.2 Maximum speed when using a collet chuck adapter
The recommended maximum rotational speed for using the collet chuck adapter OZ and the collet chuck
adapter ER, is 16000 rpm.
