Spindle rebuilt at JM CNC inc

Here is a 10k RPM spindle lubricated by grease on a Haas machine.

Our customer asked us to make some improvements to avoid future failure due ton contamination.

We have change the bearing type and we also add an extra mechanical barrier to expend considerably the life of he’s spindle.

We have completed the installation directly on the customer machine by vibration analysis and break-in period.

Final result .008 inch/sec at 10k RPM

With a final temperature of 39°C.

The break-in period took 4.5 hours to be fully completed.
