Second step
Reception inspection
- Control of the actual state with testing of the pull-in force, electrical components such as motor, rotary encoder and sensor technology. Testing of the cooling flow, measuring of radial and axial runout.
- If possible, short test run on our test stand.
- If necessary, the spindle can be disassembled.
