I've acquired a Centec 2A milling machine which has previously been used for just one specific repetitive job. This has resulted in noticeable slide way wear over the centre portion of table travel. Can anyone suggest the best way of addressing this and getting the slide ways true and parallel ? Is it something I could tackle with abrasive blocks, scrapers etc or is it a case for a slide ways grinding company ? Your comments and suggestions please,

Ken.

Hi Ken,

You would need to take the table off, then use a long camelback type straightedge to blue up the dovetails to see where the wear is. It would then be a matter of scraping down the unworn section to get the ways straight and parralell again, then check the gybe for straightness and flatness and rebuild, there are several detailed how to's on 't web I will have a look and see if I can post you some links. It is doable, but requires patience and accuracy.

Thanks Phil, as you said, plenty of information and food for thought there. The first thing must be to strip the table and cross-slide ways to measure the extent of wear to be corrected, then decide which approach to use. thanks again,

Ken.
