Spindle Repair Lab

We needed to get repaired fast.

“Our line was down and we needed to get repaired fast. The fact that MEC is located in Quebec, Canada, it saved us from sending our spindle overseas. We were up and running in a couple of weeks instead of a few months. We saved time and money!”

— Robert Deshautels

We couldn't find it, so they made it!

“We were missing a part to repair our spindle and we couldn`t find it. We called MEC and they machined for us from scratch. Their technician was a big help and spent hours on our problem. Great Canadian company!.”

— John Miller

Spindle Maintenance

Preventive maintenance on the spindle is to detect in advance possible anomalies at the costumer’s place. This procedure on a regular basis will help extend the spindle life and to minimize breakdown on CNC machine.

  • Verification of the taper run-out with calibrated test bar at 30 mm and 300 mm

  • Verification of the taper contactsurface contact of the taper (%)

  • Verification of the temperature at the maximum speed

  • Analysis of the bearings condition

  • Analysis of the vibration level in mm/sec

  • Verification of the spindle lubrication system and chilling unit

  • Testing of the retention force (Kn) of the draw-bar system

  • Proceed to the electrical test of the stator (if needed)

  • Verification of all proximity sensors
