Stop dimension of the main spindle - (only for spindle chuck data "yes")
Jaw dimension of the main spindle for jaw type 2 - (only for spindle chuck data "yes") mm
Chuck dimension of the counterspindle - (only for spindle chuck data "yes" and for a
counterspindle that has been set up)
Stop dimension of the counterspindle - (only for spindle chuck data "yes" and for a
counterspindle that has been set up)
Jaw dimension of the counterspindle with jaw type 2 - (only for spindle chuck data
"yes" and for a counterspindle that has been set up)
Tailstock diameter - (only for spindle chuck data "complete" and tailstock that has

The safety clearance defines how close the tool can approach the workpiece in rapid
traverse.
Note
Enter the safety clearance without sign into the incremental dimension.
Spindle speed (maximum main spindle speed)
If you want to machine the workpiece with a constant cutting rate, the spindle speed
must be increased as soon as the workpiece diameter becomes smaller. Since the
speed cannot be increased at will, you can set a speed limit for the main spindle (S1)
and for the counter-spindle (S3), depending on the shape, size, and material of the
workpiece or collet.
The machine manufacturer only sets one speed limit for the machine, i.e. none that
are dependent on the workpiece.
Please refer to the machine manufacturer's specifications.
