SX3 Mill Lead Screw Lubrication

[James Hall 3Participant @jameshall3]

Having owned my SX3 mill for nearly a year I'm finally getting around to fitting the DRO which has been living under my bed for the last six months.

I'm fitting the Z-axis strip and read head inside the column so have taken off the rear cover for access and find it filthy inside: remnants of casting sand, dust and grit. It's also obvious that the Z-axis lead screw and nut and the bevel gears are not, and never have been, lubricated – I'm assuming that they should be, so what with?

I've some 'general purpose' and some 'high performance' lithium based grease in stock – would these do?

This makes me wonder of the thrust bearing has been packed as I suppose it might perhaps not have been – but the dismantling required to check this would be in a whole different league.

Hi James I too have had a problem on my SX3 and was not sure on the dismantling to get at the problem.I phoned Arc Euro Trade for advice and on their website is a full guide on dismantling and reassembly,I managed it easily and if I can most competant people can.I just oil my leadscrew from an oil can,I use hydraulic oil.
