Because high speed cutting connects regular meeting to need higher rotate speed, make cutting tool allots the possibility that gives birth to broken, disintegrate to increase greatly in effect of tremendous and centrifugal force from this. Bit flies but the ballproof glass of machine tool of dislocation milling cutter is attacked to break bit flies but dislocation milling cutter is home the face milling cutter of the diametical 100mm of some famous manufacturer production. When Shandong university is using this milling cutter to install single bit to undertake cutting experiments, when rotate speed increases 5000r/min, an only razor blade carves more than in centrifugal force fly below the circumstance of an attrition force left cutter hub, stroke is in of the machine tool defend on armor plate. And an user of Suzhou is more unfortunate, the fragment after their cutting tool is broken hit the ballproof glass of the machine tool, the result is glass is attacked completely to break. So, why can the cutting tool that high speed machines be like this to destroy ability greatly? We made the brief analysis that be as follows. If of 40mm of a diameter but dislocation milling cutter undertakes machining with the rotate speed of 40000r/min, its linear velocity is 5024m/min, namely 83. 7m/s, with bit weight 0.
015kg computation, its momentum is 1.
26kg · M/s. This one result and the momentum giving chest of bullet of one famous small voice handgun comparatives (weight of warhead of this handgun bullet is made an appointment with 0.
005kg, initial velocity giving chest is 230m/s, accordingly momentum is 1.
20kg · M/s) . CNC Milling
