High-speed die cutting, hard machining and dry cutting technology has entered the practical stage, these processes can be summarized as mold machining (HPM: High-Productivity Machining).
Mold processing advantages of high productivity is mainly reflected in their finishing. Usually better than finishing a very easy access to the size of 0.02mm tolerance, and easy access to chatter is small, a small burr good surface quality, thus can reduce the amount of hand-polished 60% to 100%, so that mold productivity increased by 30% ~ 50%.
HPM unusual for high-alloy tool steel (60HRC ~ 63HRC) high-speed hard milling, the most suitable for light at the end of mold. As a result of a very small depth of cut, get thin chip thickness, cutting force is not only small, little vibration, and chip easily be ruled out, and extended tool life. Usually under the pressure of compressed air or oil mist cooling trace.
