I need to determine the dimensions for a hole pattern on a turret. I checked the operations manual for the lathe and they dont give the dimensions in there. I was just curious what an accurate method for measuring by hand would be?
We are making 7 different jaw nuts for 6 different chucks ranging in size from 8" to 18". I think we'll be making about 100 of each, so the total quantity will be something like 500 - 1000 pieces.
Yea i actually did some hardness tests on several samples and found values from about 22 - 35 Rockwell C. I know one of the companies we used to buy them from uses 1018. The large range in hardness is what threw me off, but as you stated earlier, you have seen them made from a variety of...
I am designing some jaw nuts for some chucks and was wondering what type of steel would be good for this application. My thoughts were maybe a case hardened 8620 or perhaps 4140.
Thanks for any help.
