I use dry Teflon Spray for stuff like this, slight rust prevention and no dust or chips sticking on it.

If the bearings are greased correctly, spindle temp is a good indicator of ok preload.

Thank you for the info.

I had hope that the joystick could also control axis speed with a potentiometer like this one:

If new SKF are on the way, use them. I am not sure if they have used high quality bearings in Taiwan.

Uwe

What type of joystick will work to move the axes, and could it move diagonal ?

Uwe

Perfect, the way to build a commander Kirk desk

Make a backup of the PLC before changing it, so you can go back to the last working version.

If you have set Z Ref with the probe, manual Z measure at another Z position than that of the probe will not work. If I have to set Z for a tool and do not want to use the probe while a part ist in the spindle, I make sure the tool is selected and drive it to part Z 0. Than I correct its Z offset so...

Maybe you can find a labyrinth ring seal in the right size, they could take more rpm with less friction.

Uwe

Without special equipment, brake cleaner spray and compressed air.

Will make a funny mess

Uwe

If you mean leaving the bearings on the spindle and in the head, ok. But you must remove the spindle to wash out all old grease.

I doubt it will be the seal, but also NBU15 will lubricate the seal better than cheap grease.
