The manual that came with the milling machine mentions that the unit
is covered in heavy grease and this must be removed by degreaser and
then a lubricant applied.

Can I use WD40 or similar spray as a lubricant for the milling bed ?

Also, The cutting speed guide for 5mm slot drill and aluminum works
suggests mill speed set to over 6000 rpm. The machine only goes as high
as 2500 rpm, would I just set it on the highest speed anyway ?

Thanks in advance
