Neat Machining Video

Here's a short Video of the Latest and Greatest in Cutting Tool Technology.......These parts are D-2 Toolsteel and are heat treated to 60 Rc......It used to take us about 3 hours to finish Grind the Octogon and transition Radaii between the flats
With the "New" Tools we are able to make the same part in about 2 1/2 minutes........Remember, This material is 60 Rc

What does Rc mean, (other than hardness!)?

**kwhizz** · #3 10-10-2007, 09:50 PM

Rc is the Abbreviation for Rockwell Hardness......60-62 Rc is the hardness of cutting Tools......Drills, Etc..Soft material is like 8-10 Rc just as an example

So using that scale, Belair would be a 120 Rc A$$?

At 62 RC we had trim sections in dies that would some times chip. We dropped down to 56-60 and the dies still trimmed the parts fine but didn't chip. CNC machining has taken the machine shop out of the hands of the Machinist and put it in the hands of the computer whiz. Sure cuts down on the cost of producing a big number of the same part. Once the programme is written you can go back to it at any time and make some more parts. I can remember when digital readout on the machines was a God send.

Now it is digital everything.

Without getting into Exotic materials.....about the Hardest you can get metal to harden to is about 62-64 Rc

Very cool Ken....was this done in your shop?

Kicka$$ video Ken.

I'll bet that the router bits are quite expensive...we used to use the same type of machines to route out the circuit boards at the facility that I worked at...

The vid looks good. Can't believe those cutters go thru 60Rc like that and throw real chips. Looks good so long as the numbers are there. Had a Bostomatic at my fingertips and did some hard milling in the past but the chips were usually dust. Since I have been working where I've been working, I have been designing a lot of parts that require wire work. The parts lend themselves to that process and they encourage it. You gotta wire dere on da nort side??
