My first post as I just became the owner of an Aciera f3 milling machine. It needs repairs and restoration to some degree.
After assessing the machine I noticed that the collets don’t fit and bind when inserting them. Initial thought was a bur somewhere hence I cleaned the inside, collets and checked the spline in the chuck and that seemed all smooth and clean.
Hence I checked a few collets I had and some slide in just fine whereas others bind, including new once.
When painting the collet keyway and inserting it until it binds shows that the spline inside the chuck rubs against the collet keyway bottom. Like it is to large … width of the spline seems not the issue as the collet that fits has a narrower key way then the ones that do not.
What could be the problem?
Can I cleanup the spline with a small file / diamond stone?
