日本东和冶金公司新近研制出一种粗加工用立铣刀“Suncut”,用于强力重切削加工.此种立铣刀由硬质合金制成,具有独特的形状.由于设计新颖,能充分发挥其切削性能,较之过去的带硬质合金切削刃的立铣刀,在进给量提高4倍、切削深度提高2.5倍的操作条件下,加工效率可提高9倍,加工费用不到高速钢粗加工立铣刀的一半,尤宜用于大切深加工。1.“Snu cut”立铣刀的特点,①切削抗力小;②排屑 Japan’s Higashine Metallurgical Co., Ltd. recently developed a roughing mill “Suncut” for heavy heavy cutting. This end mill is made of carbide with a unique shape. Due to novel design, fully capable Exert its cutting performance, compared with the past end mill with carbide cutting edge, the feed rate increased by 4 times, the cutting depth increased by 2.5 times the operating conditions, the processing efficiency can be increased 9 times, processing costs less than high speed Steel roughing cutter half, especially suitable for large cutting deep processing. 1. “Snu cut” end mill features, ① cutting resistance is small; ② chip removal
