Mill HEAD LINERS. Head liners are of the segmental type constructed of Manganese Steel, Chrome molybdenum, or Ni-Hard and are designed to pass easily through the manhole opening or discharge opening in the case of rod mills. For ball mill work ribs are cast with the feed head liners to deflect the ball mass and minimize wear on the headliner ...

Ball-end milling must remove a 0.3 mm allowance in the finishing pass, using ball-end mills with diameters less than 20 mm to reproduce the free-form small features. Slopes found in sculptured forms are from 0° to 90° and the fillet radius can in some applications be very small.
