8.4.5 Adjustment of sensor S1 (for all models)
After having replaced the sensor unit as described in section 8.4, adjust it as follows:
1. do not fully tighten the sensor as careful adjustment must be performed;
2. attach the tool holder cone and check that the output of S1 is "ON"; if the output is "OFF"
rotate the sensor unit until it turns to "ON";
3. the sensor “3” is eccentric with respect to the nut “5” that holds it: slowly rotate the nut in the
direction that moves the sensor away from the tool holder;
stop as soon as the output of the sensor changes to "OFF";
4. delicately turn the nut back by about 15° - 20°, so that the output of the sensor returns to
"ON";
5. manually turn the shaft and check that the signal remains "ON" for the entire rotation;
6. tighten the fixing screw “2”;
7. release the tool holder pressurising the piston at the value indicated in section 4.6 “Pneumatic
connections”, and check that in this condition (collet open) the S1 output is “OFF”;
8. remove the pressure from the piston and let the collet close without tool holder: in this
condition the S1 output must be “OFF” for the entire rotation of the shaft;
9. if points (7) and (8) are not verified, repeat the procedure from the beginning, reducing the
amplitude of the rotation performed at point (4);
10. if points (7) and (8) are verified, perform a cycle of 10 tool changes;
11. at the end of the cycle make sure the following table is met:
12. if the table is not verified, repeat the procedure from the beginning;
13. if the table is verified, make the machine perform a cycle of 100 tool changes, using the
largest possible number of different tool holders;
For HSK models gauges and thickness spacers are available for the adjustment of S1
and S4 sensors; the kit is described in the paragraphs from 8.4.8 to 8.4.10.
The use of a calibration kit allows not only faster but also more precise calibration: the
manufacturer recommends the use of the kit, given the importance in terms of safety
for the proper adjustment of the sensors.
