苏联某厂的铣工库兹涅卓夫和他的同志们共同研究成功一种新型的高效能苞米铣刀。这种苞米铣刀跟以前的苞米铣刀不同,主要的不同点是:刀齿数目较少;有更大的螺旋角;改变排屑槽的形状。高效能苞米铣刀。新型苞米铣刀的刀齿螺旋角增大到45°。端齿磨成6°的倒棱,倒棱宽1～2公厘,这样可以加强端齿的力量。刀齿上螺旋形的断屑槽不是从铣刀顶端开始,而是跟端面相隔一个距离,等于螺旋槽的宽度,约10公厘。端齿的后角等于8°。新 Kuznetsov Mills, a mill in the Soviet Union, worked with his comrades to study a successful new high-performance corn mill. This corn mill cutter with the previous corn mill different, the main difference is: a smaller number of teeth; greater helix angle; change the shape of the flute. High-performance corn mill. The new corn mill cutter blade helix angle increased to 45 °. End tooth grinding into 6 ° chamfer, chamfer width 1 ~ 2 mm, so you can enhance the strength of the end teeth. The helical chipbreak on the tooth does not start at the top of the cutter, but at a distance from the end face equal to the width of the helical groove, about 10 mm. The relief angle of the end teeth is equal to 8 °. new
