Adjusting sensor S4 (HSK versions only)
i
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.
take thickness spacers of 0.12mm and 0.16mm, which will be interposed between the stop
surfaces of the tool-holder cone and the spindle shaft, as shown in the figure below;
2.
insert and block the tool-holder cone in the spindle, and check that the signal supplied by
sensor S4 corresponds to that described in the following table:

3.
rotate the shaft manually and check that the conditions of the table are satisfied for all 360° of
the rotation;
4.
if this is not the case, rotate the sensor until you find the position at which you obtain the
output described in the table;
5.
definitively tighten the screw (3);
6.
perform a cycle of 10 tool changes;
7.
at the end of the cycle, check that the condition in point [2] of the table is satisfied for all 360°
of the rotation of the shaft; if this is not the case, repeat the procedure from the start;
8.
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;
9.
at the end of the cycle, check that the condition in point [2] of the table is satisfied for all 360°
of the rotation of the shaft; if this is not the case, repeat the procedure from the start;
10.
if the condition in point [2] of the table is satisfied, the adjustment of S4 is complete.
