我厂五车间铣工赵帮志同志,在加工某工件时,学习了苏联先进经验,采用多刀铣头进行高速切削,提高了工作效率5倍多,并且保证了质量。高速多刀铣头的结构如图1,图中1是刀杆,按铣床主轴锥孔配制,45号钢,热处理后 Rc 35～40。2是刀盘,45号钢,热处理后 Rc 35～45。刀盘上开有八个方孔,用来安装刀头。这八个方孔是这样排列的:在φ185公厘直径的圆周上有4个等分方孔;在φ18l公厘直径的圆周上有4个等分方孔。3是垫圈,4是螺帽,用来将刀盘和刀杆聚固在一起。5是螺钉,用来紧固刀头。
When I worked on a certain workpiece, I learned the advanced experience of the Soviet Union and used multi-tool milling heads for high-speed cutting, which improved work efficiency by 5 times and guaranteed the quality. High-speed multi-head milling head structure shown in Figure 1, the figure 1 is the arbor, according to milling spindle spindle preparation, 45 steel, Rc 35 ~ 40.2 after heat treatment is the cutter, 45 steel, Rc 35 ~ 45. There are eight square holes on the cutter to install the cutter head. The eight square holes are arranged in such a way that there are four equally divided square holes on the circumference of φ185 mm in diameter and four equally sized square holes on the circumference of φ181 mm in diameter. 3 is a washer, 4 is a nut that is used to hold the cutterhead and arbor together. 5 is a screw, used to tighten the blade.
