VM25L R8 mill bad noise on spindle.

It could be incorrect preload or just the poor quality bearings they use in the machines in the first place when I bought mine I spent a few days stripping it down cleaning it and reassembling with fresh grease from the factory they are not well adjusted it was time well spent and cut my backlash in half

the supplier I used were Simply Bearings Ltd

I'm not sure if your machine will use the same size bearings as mine I would assume so but you know what they say about assumptions
These are the bearings I used
1 x 6209LLBCM/5K NTN
1 x 6007VV NSK
1 x 32005X/Q SKF
1 x 32007X/Q SKF

Yuo've got to partially dissasemble to check/adjust the preload so you could check the bearing sizes then

Many thanks for your detailed explanation

I will check out the supplier and understand preload.

Many thanks
