So, I have a cheap quick change tool post. It's the wedge type, it doesn't say anything on it except Made in China, so I don't even know the brand. It takes the 250-xxx tool holders. I just picked up some cheap tool holders and was pretty impressed by the fit and finish.( HAH! I just came up from an experiment and one of the set screws broke when I tightened it! ) I mean, they were 11 bucks a piece. I bought some 18 dollar a piece tool holders a year or two ago, and they only fit on the side of the tool post, not on the front, and they were a little rough. The knurling wasn't great on the height adjustment nut, and the surface was pretty rough where they cut out the slot for the tool. The new ones are much nicer finish-wise.
So I'm wondering what I'm not getting, since it's not an Aloris or anything. ( Obviously well tempered set screws for one thing ) . I have some Borite 1/2" carbide insert tools that take the little triangular inserts. I centered the tools so they don't leave a little nib on a facing cut, and then I put the toolholder on the side of the tool post, and switch the tool around and they don't leave a little nib on a facing cut.
And I've taken them off and put them on a few times and they still make a nice smooth facing cut.
Obviously, set screw aside, if I can't tell, then it doesn't really matter. But I'm curious if you can check a tool post for accuracy, and what you would check if you did check it. Or is what I did the test?
