Looking to streamline/organize some second lathe ops on my products and trying to do away with collect stops. I'm looking to getting some brass emergency collets and just boring them to the size and depth I need for each part but I'm not sure how well they will hold up over time.
Lathe is cnc with pneumatic closer. Any guess on how many cycles the brass will hold up to? I'm sure steel emergency collets will hold up a lot longer but prefer the brass plus it will save me the time of making more split brass bushings. Parts are cosmetic so avoiding marks and scratches are a must. Material being held is 6061 and 7075.
TIR will need to stay under .0025" so not very critical. I'm guessing the Z depth of the brass collet will change with wear over time which I can deal with.
Thanks in advance.
