我厂铣削加工Z512～1型台钻底板槽时,以往采用镶片高速钢三面刃铣刀及焊接式硬质合金三面刃铣刀,但这些刀具在加工中存在铣刀损耗量大,生产效率低等问题。在工人同志和技术人员的共同努力下,经过多次试验改进,革新采用了机械夹固式硬质合金三面刃铣刀(附图)。 I plant Z512 ~ 1 type bench drill floor groove, the past, with high-speed three-sided veneer cutter blade and carbide cutter three-sided edge cutter, but these tools exist in the milling cutter loss, production efficiency Low-level questions. With the joint efforts of the workers’ comrades and technicians, after several trial and improvement, the mechanical clamping solid carbide three-face milling cutter was adopted (with photos).
