6.5 Optimize the spindle
6.5.1
Set the machine data for the spindle
Checking the machine data settings
Match the machine data default settings as well as all relevant parameters for spindle/axis
interpolation with the machine data in the following table. The example is true for a spindle
motor without mechanical gearbox stages with 8000 rpm.
The
machine
data
can be initialized with the suggested values shown in the table. The values
vary depending on the application.
