How to properly run in spindle bearings.

[driftspin]

As magicniner says, the manufacturer is the first place to ask, followed by the bearing manufacturer.

However, the general process will involve running at gradually increasing speeds with no load for periods of time, while monitoring the temperature.
If you read the last paragraph of this post - http://www.mycncuk.com/threads/10344...8817#post88817 (should be post 36 in the thread..) it describes how I ran in my Triac spindle after changing the bearings. You'll obviously want to adjust the chosen speeds to something a bit more suitable, as the Triac spindle is only rated to 3000RPM.

M-C thanks for that.

I have been running the spindle of and on with no load for +/-2 hours i checked total running time, so not just 30 min... also in various speeds just testing the uccnc vs UC300eth vs bob vs vfd pin out.

Also i had no clue about the effectiveness of my cpu watercooler radiator cooling i have.

I have not done any prolonged cuts but no rise in temperature was noticeable during +/- 30min action in 1 go.

Grtz Bert.
