Then increase the speed to the nominal value, and repeat the same run/pause interval again for
5 times.
After this, let the spindle run for 30 minutes at the nominal speed without load. After 30 minu-
tes, pause for 5 minutes, then let the spindle run again at nominal speed for 30 minutes.
During the running-in, always control the temperature of the front partition of the spindle. In
case it gets warmer than 40°C, immediately stop the run and let the spindle cool down to room
temperature. Then continue the run.
After successful dispension run, the spindle can be used normally.
Note: During the dispension run, the bearings get warmer than usual and the speed can fluctua-
te irregularly. This effect is normal and will disappear after some hours.
8.3 General operating condition in regular use
It has to be ensured, that no collisions happen during using!
Collisions can be caused on one hand by touching rotating parts
without blade (tool shaft, motor shaft, clamping nut) with solid
parts (work piece, machine), on the other hand by wrong cutting
parameters (rpm too low, feed rate too high), improper tools or
too hard work piece materials. Unnoticed collisions can cause
heavy damages at the machine and lead to an increased risk of
accident. Especially because of this reason it is necessary, to
never let the machine run unsupervised. In addition to this it
always has to be ensured that the motor spindle reaches working
speed before the tool is cutting the work piece at first time.
Temperatures of coolant and spindle housing
The allowed temperature of the coolant must be between 10°C and 30°C in normal working
condition. If the coolant temperature increases to more than 40°C, the spindle has to be
stopped immediately, the reason for overheating must be clarified. In case that the coolant
temperature is below 15°C, the running-in times need to be doubled. The maximum allowed
pressure of the coolant pump is 2 bar.
