一般标准的锯片铣刀只有一面刃口。我厂用φ150×3.2的标准锯片铣刀在加工槽时,经常有崩裂现象。究其原因主要是零件的槽深(45公厘)且窄(3.2公厘),铣削时所产生的切屑除了一部份被刀刃带走之外,其余都挤在据片铣刀的二侧。由于锯片铣刀的两侧没有刃口及容屑槽。因此切屑在铣刀的槽内不断发生摩擦,产生大量的热使锯片铣刀膨胀而卡在槽内,结果产生崩裂。 General standard saw blade cutter only one edge. I plant with φ150 × 3.2 standard saw blade milling cutter groove, often cracking phenomenon. The main reason is that the parts of the groove depth (45 mm) and narrow (3.2 mm), except for the milling of the chips generated except by the blade away, the rest are in the film cutter on both sides . Because there is no blade on both sides of the blade cutter and chip flute. As a result, chips constantly rub in the groove of the milling cutter, generating a large amount of heat causing the blade cutter to expand and become stuck in the groove, resulting in cracking.
