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  Ken

Re: Neat Machining Video
What does Rc mean, (other than hardness!)?

Re: Neat Machining Video
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

Re: Neat Machining Video
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.
