I don't know if this is the proper forum for this question but here goes.
I use chucking reamers when I need to get a deep bore to a tight tolerance. I usually open the bore up to within .007 of final dimension then use a reamer to finish.
With this being said I am not sure if I am reaming correctly. I will apply plenty of cutting fluid and advance the reamer about .020 to .050 at a time and while the piece is still turning I retract the reamer to clean. Then add more fluid and repeat. Is this the correct way to ream?
The next question I have has to do with buying used reamers. Until now I have always purchased a new reamer for the job that needed to be done. The project I am doing now I need to make sure I have a 1" through hole for 6". Tolerance +.0015/-.000
The price for a new reamer this size is like taking out a second mortgage so I found a used set of Millersburg reamers that appear to be in pretty good shape and cover a variety of sizes for less than the 1" reamer costs by itself. I was thinking about purchasing them and then having them sharpened.
Does anyone have a better way to do what I need to do?
Has anyone sharpened reamers or had them sharpened and them not losing dimension?
Where would you have them sharpened at?
Any ideas or guidance would be appreciated.
I know just enough about this machining thing to be dangerous. LOL
Thanks Vince
