Corner Rads

Question for the group

actually related to machining

If a person was to create a formed file for knocking .015 to .06 corner rads on carbide and HSS end mills

would anyone be interested in trying this out.

if so let me know im looking for feedback on this

thanks a bunch

Do it all the time. Use diamond hone for carbide, India stone for HSS. Best is: buy'em done from thew factory. Carbide cutters are readily available now with some variety of corner rads.

How do you plan to create relief on the cutter edge?

I used to do this all the time using a simple india stone....yes on carbide. It wore the shit out of the stone....but the material removal rate on the endmill was very controlled & very consistent flute to flute. Easy to control the relief also....all depended on what angle you hold the flutes to the stone. Enter modern times, when having a proper coating means EVERYTHING. Taking a coated endmill and stoning a corner rad onto it works in a pinch....however most all mfg's now produce tools with common rad's....coated off the shelf.

Jeff,

Grow some and stop beating around the bush.

  1. I'm interested in the details on your Cuttermaster Pro that was suppose to be available in June 09.

  1. I'm interested in trying your files.

  2. I'm interested in that unique wheel you show on your website.

  1. I'm interested in an affordable optical drill grinder like the Optima.

  2. I'm *NOT* interested in the cheap Chinese drill grinders that you sell. There might be an idiot shop owner in Valencia, CA who buys cheap Chinese Kurt knock off vises at auctions and thinks he got a bargain that is.

Good Input Jon . re the Pro:

formatting link
the pro is almost done waiting on electrics wheel covers and paint (is variable speed) Conquest in California is ready to build. if youd like to try a GS drill point grinder let me know ill send one down , they are a step way up from Darex the Diamond Corner Rad file seems to work quite well , you can get a .

02 rad in about 3 strokes , thought it best to offer a good corner prep solution with my equipment.

give me a call if you have any questions or would like to try a file , the wheels will be out this fall

Lots of good ideas. Needs a built-in video inspection system and a reasonable price.

You mean a monoset?

At the moment I don't think it's made yet.

If you need video inspection get a "smart scope" machine. That SOB can check any thing! just by using a B/W grayscale camera. Whadya mean the company cannot justify 30K?

mono who? is that what you call'em? To the best of my knowlege they are, as previously stated: cincinnati tool & cutter grinders. Lots of big shops/manufacture's had'em in the day. Usually a tool crib attendant(hehehe) would spend his down time sharpening the plants tooling, be it end mills, drills, reamers ect & even places that had Brown & Sharp Screw machines, making cams & tooling Ah yes those were the days, sulfur oil, pimpley legs from oil soaking thru your rubber apron, my Dad would say, he was a Screw Machine guy. A whole days work would fit into 2 5gal buckets. lots of those old B&S's have been converted to CNCs!

Wonder if he'll send me the one that's on the skid at his shop on consignment? I'll test it for him - free of charge- so he can make improvements. Fuck the video, big ass magnifier lens - well lighted. Maybe with cross hairs on it, kinda like a shadow graph.
