I drove up to Dallas this morning to have the beat-up top of my milling table ground. Great shop, good visit, I was in the shop by5:30 AM and back on the road by 7 AM. One of the guys running the shop showed me the biggest blanchard grinder I've ever seen. The table was 300" diameter, grinding head maybe 6-8 ft. dia. And yes, that was all magnetic chuck, in big wedges. The thing had a 10' tall or so circular fence that closed on rails for operation. Yes, they could have blanchard ground my suburban. Little dinky ass workpiece they were setting up was only a few inches thick and 4-6' on a side.
Lots of other cool toys in there, too. Grinders all over the place, machining centers, abrasive water jet, etc. And they were very busy, jobs running on most machines.
Back home by 9:40 AM. I need a nap now.
