Thread: Tripet Surface Grinder

Hi Bob,

Nice machine, a couple of questions.. I take it that flat belt is "slipped" for table cross feed? (Edit:... Ok, I got it it's hydraulic X and Y)

Is the spindle motor inside the column? Edit: No the belt drives the spindle.. must be a complex drive mechanism...

No coolant? Edit No coolant

How does the downfeed work?

Regards
Ray

That is a lovely grinder. Looks too good to use! Does this crew make magnetic chucks? -You don't see them around that much anymore.

To add to Rays questions, What are the handles that look like they are for locking the spindle for?
Stuart

Unfortunately boys, William Brem isn't my next door neighbour. You blokes know more about surface grinders than I do. I've never had the opportunity to use one. I posted the photos simply because the machine is a little gem and I wanted to share it with the rest of you.

Thanks Bob, It's a little gem of a surface grinder, I think you definately need this machine!

Hi Stuart,

I'm guessing that's exactly what they are, locking the spindle to change wheels. I like the look of the top mounted wheel dresser.



Do you think that lever on the top is for moving the dresser across the wheel?

Yeap, I was going to pm you about that, you saved me the trouble. You'll see its been moved between the pictures.
You think there is any chance of stiffening up the one on your grinder?(I'd have to say it was the crappiest looking piece of kit in the place, but given the quality of what its attached to and his other machines I'll let him off) As far as fixing it goes it would have to be parallel to the table.

I'd been thinking those handles locked the spindle by tightening the bearing up. They might work the same way as the quill lock on a mill?

Hi Stuart,

Funny you should be thinking that, I was wondering the same thing.

Getting it parallel to the table is the trick, and that's the big advantage of a table mounted dresser, that it's automatically parallel.

Why dose it matter about having the diamond parallel to the table?

Because if it isn't then the grinding wheel wont be parallel to the table and you will be cutting with one edge of the wheel(same as a mill being out of tram)
Stuart

Where and what are you using to dress the wheel?

PC,
I'm not using anything, I don't have a surface grinder.
If you look on top of the wheel guard in this picture you'll see what we are talking about.

We believe its a wheel dresser, Ray has something similar on his machine but I was told it doesn't work very well.

Stuart

Actually it looks like you can offset the grinding head - nice.

So all this reference to parallel and traming is in relation to a dressing device attached to the wheel guard,not a dresser attached to a Magnetic chuck or held in a vice.

I think you're catching on ... the question (Stuart and I were discussing) is how to make sure that the top dresser is parallel to the chuck...
