I would like to know what the retention force is for automatic drawbars on machine spindles by taper #50, 45, 40, 30, NMTB and HSK 50, 63 and 80. I have a pull force gauge and was told it is out of spec and needs to be calibrated. How much can the actual force vary from the spec. + or - lbs. of force?
