Our repair process

Preliminary testing
At arrival, a complete analysis is performed to identify mechanical and electrical problems. The main tests proceeded are pull force, taper run out, sensors state and test bar.
Once tested, the spindle is completely disassembled. Furthermore, parts are cleaned and inspected to see if they are damaged.
Dimensional measuring and electrical testing
Measuring of all precision components performed in our metrology room along with stator and electrical components testing. Following, a detailed quote showing technical problems, repair solutions, prices lead time and picture of damaged parts is sent to customer.
Repairs and assembly
Multiple solutions can be proceeded on the spindle such as parts in-house machining, taper grind, dynamic balancing and rewinding of stator. Moreover, contaminated parts can be replaced by new OEM spec ones including bearings, seals, o-rings, encoder, and rotary union, etc. At last, the spindle is fully assembled.
Final Testing
The spindle is tested on one of our test benches up to full speed making sure temperatures, vibration, and all features are working correctly.
Quality Control
The spindle goes through a quality control where all functionalities and systems are analyzed. After, the spindle is well packed and shipped to the customer place.

Analysis of the spindle 

During the preliminary testing, each spindle is analyzed meticulously. Our technicians are executing various tests on it to detect possible problems. Doing that helps us to understand better your spindle condition and to propose you the best solution.

What we test

• Verification of run-out with calibrated test bar at 30 mm and 300 mm.
• Inspection of the taper surface contact (CAT, BT, HSK, CAPTO).
• Investigation of the temperature at maximum speed.
• Analysis of the bearings condition.
• Checkup of the vibration level in mm/sec.
• Verification of the spindle lubrification and cooling system.
• Testing of the retention force (Kn) of the draw-bar system.
• Complete winding system analysis.
• Assessment of status for all sensors.
