The plano-miller employ multi-point milling cutters with changeable tips this technique has been perfected eyeing the economics due enormous machine time saving controlling table speed that house rotating cutter shaft does conversion by the tool post by milling head of fabricated box construction taper roller bearings take care of thrust and radial load surface finish on milling heads is also better as compared to that achieved with single point tool machining time and hence costs are trimendously saved by converting conventional planers to plano-millers
