Surface Grinder Restoration
Join me in the machine shop for the surface grinder restoration. This is a precision surface grinding machine that I inherited from my grandfather. It is an industrial machine tool designed for the sole purpose of making parts extremely flat. So why on earth would a hobby machinist require such a specialized piece of equipment in his manual machine shop. Well, because it’s cool of course! This surface grinder includes a magnetic chuck, a flood coolant system, and a dust collection system. All of which are a complete mess. And there are even some broken bits in the mix. So I’ll be unleashing my arsenal of rust removal techniques. Including, but not limited to, the sandblasting cabinet, scotch brite pads, evapo rust, and more. Once everything is cleaned up, repaired, and reassembled I’ll go through the process of dialing in this machine. This includes leveling with a precision level, grinding wheel dressing, grinding wheel balancing and resurfacing the magnetic chuck.

With regards to the ball bearing ways, on a traditional way the thickness of the oil film between the ways will vary with traverse speed and temperature and all that viscosity and shearing forces stuff. That said I have a boyar schultz with traditional ways and it can hold a tenth just fine if you take your time.
That’s a good point. I hadn’t considered that advantage at all. But sounds like the variations are on a scale smaller than the accuracy. At least based on your experience.
Ah that makes sense… from what I’ve gathered most automatic surface grinders run on traditional ways. But maybe this is just because it’s more of a captured design that works better for the drive mechanism.
