Adjusting sensor S1 (both ISO and HSK versions)
Only for HSK versions: for the adjustment of HSK F63 sensors, a kit of gauges
and thickness spacers is available, described in section 8.8.18.
The use of the kit allows a quicker and more precise adjustment: HSD S.p.A.
strongly recommends the use of the kit, given the importance (for safety purposes)
of a correct sensor adjustment.
After replacing the sensor as described in paragraph 8.8.12, calibrate it as follows:
1. insert the tool-holder cone and ensure that the output of S1 is "ON"
if the output is “OFF”, rotate the sensor unit until it becomes “ON”;
2. rotate the bush slowly in the direction that takes the sensor away from the tool-holder;
stop immediately when the output of the sensor becomes ”OFF”;
3. carefully rotate the bush back by about 15° - 20°, so that the output of the sensor returns to
“ON”;
4. rotate the shaft manually, and check that the signal remains “ON” for the whole rotation;
5. tighten the screw (3);
6. unhook the tool-holder by powering the cylinder, and check that in this condition (collet open)
the output of S1 is “OFF”;
7. by means of the cylinder, let the collet close without a tool-holder: in this condition, the output
of S1 must be "OFF" for the whole rotation of the shaft;
8. if points [6] and [7] are not satisfied, repeat the procedure from the start, making an even
slighter rotation movement at point [3];
9. if points [6] and [7] are satisfied, make a cycle of 10 tool changes;
10. at the end of the cycle, check that the conditions in the following table are satisfied:
CONDITION
S1 OUTPUT
tool-holder locked
ON *
missing tool-holder
with closed collet
OFF *
collet open
(tool-holder ejected)
OFF
* for the whole rotation of the shaft
11. If the conditions of the table are not satisfied, repeat the procedure from the start.
12. If the conditions of the table are satisfied, perform a cycle of 100 tool changes with the
machine, using the maximum possible number of different tool-holders.
13. At the end of the cycle, check that the condition of the table at point [10] is satisfied. if this is
the case, the adjustment procedure for S1 is completed; if this is not the case, repeat the
procedure from the beginning.
