Tool Makers V-Blocks

**rossbotics** · Jan 7, 2019, 05:03 AM

Over the weekend I was thinking about what tool I didn't have as far as machine shop tooling, On several occasions I have had the need for a pair of small V-Blocks just to fit the mill vise, I went to the steel rack where I keep my small pieces and found a piece of 4140 1.000" x 1.500" X 4.000", so I cut it in half and machined the blocks to the specs I wanted, I stamped the numeral 1 on one end of each block for a reference then oil hardened and tempered them, I cleaned them up and ground them together making a matched pair, I didn't take any manufacturing photos but took a few photos of the finished blocks and the cad drawing.

As always thanks for looking and happy machining

Nice set of V-blocks Doug.

I like the mounting holes which my small set does not have. Makes mounting on a tooling plate easy.

Cheers, JR

When I have made pairs of things like V-blocks I do not cut them in half at the beginning. I make a cut on each face less than or equal to 1/4 of the material thickness. Then I do the grinding with it as a single piece. When finished I cut through and face off the ends.

Well it's fine to make them in one piece as long as your not using hardened steel.

Doug,

You have lost me there. I have done it with hardened steel, what problem do you see?

Tony I understand what you're saying about how you would have done something like this, and I don't see anything wrong with your approach, I guess thats just the difference between two different tool makers.

Cheers

Of course.
My initial post was not meant as a "mine is better than yours" approach.

Considering the time difference you must be an early riser.
