Express commercial corporation manufactures a range of roughing end mills [hog mills] with ground profiles for heavy cuts and stock removal without vibrations. These machines are suitable for both conventional and cnc machines. These roughing end mills are supplied with a sinusoidal radially relieved ground profile with full radius on each chip-breaker tooth and full radii grooves between the teeth providing easy disintegration of chips into fragments without chatter even on heavy cuts. The tooth of these roughing end mills can vertically transmit cutting pressure along the tool reducing the lateral pressures and the consequent deflections considerably and thus reduction in working energy is acquired to a great extent. The uniform ground profile and controlled concentricity in the machine bring all cutting edges into simultaneous engagement during operation which prolongs tool-life and reduce cold built-up at the edges. The improved concentricity in the work of the mills result in bright surface finish and substantial saving in power. The roughing end mills are available with technical specifications like significant 70% high productivity increase and over 30% can be accomplished. These end mills are constructed from imported hss stock conforming to aisi m35 [5% co] and aisi m42 [8% co] grades for optimum performance and heat-treated in closely monitored conditions to withstand extreme machining loads.
