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

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

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

Pretty Cool Ken, that is very nice . Looks like it's time to paint the cabinet again . I worked for Wolverine tube years ago and if you had more than 5 minutes down time someone was handing you a gallon of paint and a brush... Never saw so much green paint in my life... I think some of the machines had 6 inches of paint on them .
