标准切断铣刀的缺点是,刀齿在辅助面内没有后角且副偏角很小。因此刀齿在辅助面上转角处,基至在磨损不大时,也会形成较宽的摩擦面积,致使切削温度增高,并使切屑和铣刀卡住。所以标准切断铣刀上的每齿进给量 S_(?)≤0.02mm.苏联卡卢斯发动机制造公司研制出一种具有新型切削刃的宽度 B>2mm 切断铣刀(作者发明证书1209382),见附图。这种铣刀沿其切口宽度能保证分屑,而且在高的切削用量时它
The disadvantage of a standard cut-off cutter is that the cutter tooth has no relief angle in the minor plane and the minor declination angle is small. Therefore, the auxiliary cutter teeth on the corner, based on the wear is not, it will form a wide friction area, resulting in increased cutting temperature, and chip and cutter stuck. Therefore, the standard cut off the cutter on each tooth feed S _ (?) ≤ 0.02mm. Soviet Union Carus Engine Manufacturing Company developed a new type of cutting edge width B> 2mm cut milling cutter (author certificate 1209382), see Attachment. This cutter along the width of its incision to ensure that the chip, but also in high cutting the amount of it
