Hurco VM30 - Machine Warm-up and Spindle Run-in

VM Series Maintenance and Safety Manual 704-0212-209 Machine Maintenance 3- 33
Machine Warm-up
 Daily: Warm up a machine that has been idle for eight hours before cutting parts.
The warm-up cycle takes less than 16 minutes to complete, depending on the maximum
spindle speed of your machine. A 30,000 RPM spindle takes around 30 minutes to
complete the warm-up cycle.
Control power must be on and the axes must be calibrated before the machine can be
warmed up. During warm up the spindle speed is incrementally increased and maintained
for a specified time until the maximum RPM is reached.
Warm-up Procedures
The table below shows the order of spindle speed and run time intervals necessary for
