I have a CNC lathe and the bar stock seems to be running on the plus side of the nominal stock size. Can I get the collet to open up a little more to handle that diameter variation?
"Yes. You can adjust the collet to open approximately .008" more. During setup procedure, the collet body or the draw tube adapter was set with a .030" clearance between the front of the body, or adapter, to the back face of the spindle mount. This amount can be decreased to .005", which will allow the collet to open approximately .008" more. Make certain there is at least .005" clearance, otherwise the face of the body/adapter will hit the back of the spindle mount and cause damage to the assembly and/or the machine tool."
