The Home Machinist!

2" bushings needed shortening as well as ID and OD changed.

Needed .002" off of the OD, so the soft jaws were pre-loaded and cut to accept the bushing flange. The bushings then ran dead concentric to the spindle axis, so shaving .002" from the OD was easy.
Now the ID gets sized.

I found a 40" length of aluminum bar just waiting to be useful...

I'll de-bur them as I use them.

That should do it for soft jaws for quite a while, and the CNC mill is quite happy.

The entire gray area is the diamond as they are a tetrahedron shape bedded into the shank.

The area you refer to is just an inclusion.

It's seen better days, though!

The typical holder restrains the diamond at an angle, so simply rotating the diamond will present a sharp edge. That's assuming one rotates the diamond. The diamond on my OD grinder has a hexagonal area just below the diamond. I rotate it one flat every three wheel dressings or so just to present a...

We took quite a while to get to, "Steve was right in the first place"!

Well,I guess it had to happen sooner or later...

I'm thinking that it has more to do with the size of the diamond. These wheels like an open face, and a larger diamond with greater surface area may crush the bond more and close it up, "dulling" the wheel. The smaller diamonds in a cluster dressing tool would tend to "open" the wheel up more. Possi...

BENEFITS 3-5 times more life than aluminum oxide wheels, for maximum productivity. Double (2X) rough stock removal rate compared to conventional abrasives. Less burn, less dressing; most consistent performing wheel. Highest stock removal rates, maximum productivity, longest wheel life and lowest ove...

Conrad, I bought a 5SG60 wheel to try and it has hardly been off of the spindle since. It's my "go to" wheel for sure. I mounted it on an adapter with balancing capability and balanced it using a Stuhr. I also use flood coolant, but I am curious as to what you are dressing yours with. Norton recomme...

That looks like a mighty nice finish for CRS!

Concrete is easy to drill.

Unless luck finds you hitting the rebar!

and around $165 for the fractionals. How the hell do they get away with charging five times that!! I bought mine from Suncoast...

Never ceases to amaze me...

MSC is $169.56 for the fractional set.

Now that we have an item number, I'm showing $410.88 from MSC as well. Both Suncoast and MSC show the retail price at over $600.00. The Suncoast price is definitely a good deal at $229.22. Before you buy, you might check Hemly tool, as they sell the same set for 208.75. Or, you can buy them from dir...
