齿条一般是在铣床上加工。图1所示的工件在铣床上是不能加工的。这种工件如果模数小,在7417型插床上可以用样板刀进行加工。但是当模数等于8时,在7417型插床上用样板刀切削就会发生问题,因为切削时先用切刀开槽,再用样板刀加工,切削到最后,由于齿形大,样板刀切削的面积也就大,会使切削产生困难,如果加工钢料,问题就更大。经过大家 Rack is generally in the milling machine processing. The workpiece shown in Figure 1 can not be machined on a milling machine. If the workpiece such a small modulus, in the 7417-type slotted plate can be used for processing knife. However, when the modulo is equal to 8, a problem occurs with the model knife cutting on the 7417 type slotted bed because the first cutting with a cutter is slotted, and then the model knife is used for machining to the last. Due to the large profile, the model knife is cut The area is also large, will make cutting difficult, if the processing of steel, the problem is even greater. After everyone
