Conundrum? Decent benchtop surface grinder
Benchtop? Er, small stand-mounted model would do. Is there anything
decent and frugal? |

Surface grinder with a bed, not the wheel grinders. Already have one of
those. Ignoramus30330 wrote: On Tue, 31 Jul 2007 09:48:17 -0500, Louis Ohland wrote: Benchtop? Er, small stand-mounted model would do. Is there anything decent and frugal?

Benchtop? Er, small stand-mounted model would do. Is there anything decent and frugal? Doubt it. The smallest one I've ever seen was small, about 1.5 ft wide by 2.5 ft long, but it had an integral base. It wouldn't take up much more room than a small stand model, though. I know it's older, dunno the exact model or manufacturer. |

Conundrum? Decent benchtop surface grinder
Searching ebuy for surface grinder. Here's one in Wisconsin, but I think
it would probably collapse the steps down into the basement, plus it's 230v/3PH. Louis Ohland wrote: Hmm, the game's afoot, Mr. Holmes!

Nice little Clausing, but 240/3PH. Oh, my, my, my.

Horrid fright and grizzly seem to carry the same surface grinder from
central machinery. No coolant channels. Looks to be dry grinding only. Louis Ohland wrote: Searching ebuy for surface grinder.

Uh, a VFD will interface to my single phase, 20A 155v line?

Yup, 155v. Everything is a little bigger here in Wisconsin.

Yes, though if you actually have 155V you've got a bit of a problem there. The VFD normally expects 200-240V input, and yes single phase in and three phase out.

Either way, it's well out of spec for US utility standards. Pete C. PS: I'm in TX where everything is indeed bigger, and we still have pretty close to the expected ~115/230V service. My UPS reports 119V at the moment.

Uh, SARCASM:ON The 115v in my house is standard. I was being cheeky
about typing 155 instead of 115. Thanks for the link. "Do you want to fight, or do you want to surf?" "I'll surf, Sir!"

1 HP 208/220 3 PHASE 2.8 AMPS
The FM50 shows 4.2 and I assume "Full Load Amps" I _think_ the Clausing is rated 2HP / 230v Pete C. wrote: TECO FM50 AC Drive, 1 HP, 115V 1 PH Input, 230V 3 PH Output, 4.2FLA, IP20 http://www.factorymation.com/s.nl/it.A/id.193/.f Something like that, though normally the input and output voltages are the same.

According to Louis Ohland :
Benchtop? Er, small stand-mounted model would do. Is there anything decent and frugal? Yes -- if you don't insist on the company still being around. Look into the Sanford line of surface grinders. The smallest of them can be used as benchtop machines, as I use mine. But apparently the company went under shortly after I got my manual from them. (The machine was quite old, and needed a bit of modernization of the power supply for the electro-mag chuck.
