P1, P2, P3: Chuck section (left)
P7, P8: Spindle section (left)
- Set the X axis coordinates so that P1 > P2 > P3 is established.
- The P3 and P7 Z coordinates and the P6 and P9 Z coordinates shall be equal.
- If there is no spindle inner diameter, set the P8 X coordinate to the same value as P0.
If a spindle section is not to be set, set the P3, P7 and P8 values to the same values, and the P6, P9 and P10
values to the same values. The barrier range will be as shown below in this case.
i) For external claw
P3,P7,P8
P0
