  • As some of you know, I have wanted to stop managing H-M for some time. It's a tremendous strain on my personal life. I want to set up my own shop. In September, September 15, to be exact, it will be 8 years that Hobby-Machinist has been in existence.

    I have been training VTCNC to run things here. Dabbler is going to learn too. I feel that they are ready to start taking over the operation. I will be here to help in case they need, but I don't think they will. Tony Wells is and will be here also to consult with. I will be doing backups, upgrades, and installing addons. Other than that, I will not be around. I am leaving this place in good operating condition, and financial condition.

Make a slide to hold your HSS at various angles, obtain a couple of cup wheels and really go to town. I'm envious.

Open the picture fully, and see that a protractor was provided with the grinder and accessories.

A protractor's fine, I didn't have one, made a couple of slides with specific angles for various cuts. (Didn't see/notice the protractor at first.)

Congrats! With the right wheels, that will grind HSS just fine. They work well for brazed carbide tooling, which is what I think they were intended for. For inserted carbide, an Accu-finish works well.

Expensive tool, and that one looks brand new! Very nice.

thanks for the kind words and advice.....

Mikey, I do a lot of Business with Baldor I mentioned to my salesman a month or two ago that I wanted to start grinding HSS this was sitting in my office this morning!!!!! I couldn’t justify buying something like this personally it floored me. Any advice on wheels would be much appreciated.

You have a really nice salesman - that is a $2,000.00 grinder! Which I do not own ... :(

If you're going to grind HSS, the best wheel to get would be a CBN wheel. Not much choice for a 6" cup wheel with a 1-1/4" arbor and 1" wide face. Shars has some: http://www.shars.com/products/abrasives/diamond-cbn-grinding-wheels/6x1-d6a2c-cbn-plain-cup-wheel

Maybe see if they have a coarse wheel and a fine one. I know that 80 grit will shape a HSS tool and I would guess that a 220 or finer will get the coarse marks off.

Aluminum Oxide wheels are plentiful. You'll have to ask the guys with a tool and cutter grinder for recommendations.

I don't use wheeled grinders for tool grinding; I use a belt sander. Do you happen to know the Wilton or Burr King salesman? :p

You can grind end mills and drill bits with the right set up with that machine. You suck imho.

I have the same grinder you will be very happy with it after a quick learning. I have a a white I believe aluminum oxide on one side and a 180 grit diamond on the other. The aluminum oxide grinds hss very well and leaves a mirror like finish. The diamond plows through carbide also. The diamond will grind hss but not for it as it will degrade the wheel fast. You can also use a green wheel high I think is silica carbide maybe. My favorite has been the white but I don't have a lot of experience it just works good.

Cadillac, do you have any idea of the grit your white wheel is?

Sorry their are no markings on hub of wheel. Wheels came with grinder so Idk what grit. To me it’s a fine 180 or 220. I see the same composition on a lot of tool grinders. Leaves nice fine finish. Hope it helps somewhat.

Wow googling shows they are getting hard to find for some reason. And thank god I got two with my grinder cause they cost more than I paid for my grinder. I see the silicon carbide “green” wheels are available and it looks like I was wrong on grit size. The AO wheels I’ve seen are 46,60,grits.
Here’s one from MSC

Sorry for blur screen shot but msc has them.
