在万能铣床上铣削螺旋槽,是每一个铣床工人经常会碰到的。例如,螺旋齿轮、麻花钻头、螺纹铰刀、滚刀等,它们的斜槽都是成螺旋形的。铣这些螺旋槽,除了必须懂得它的原理和计算方法以外,还要会运用铣床挂轮表,找出挂轮齿数(凡是有关铣床的书或手册都印有这个表,这里就不列出了)。普通的铣床挂轮表,是按铣床丝杆导程为1/4″制成,一般铣床工人都用习惯
Mill milling spiral groove on a universal milling machine, is often encountered by every milling machine workers. For example, helical gears, twist drills, threaded reamers, hobs and the like, their chutes are all helical. Milling the spiral groove, in addition to must understand its principles and calculation methods, but also will use the table to find out the number of teeth hanging wheel (usually on the milling machine books or manuals are printed with this table, not listed here ). Ordinary milling machine hanging round table, according to milling screw lead for the 1/4 "made, the general milling machine workers are used to
