在大量制造的工厂中,各种飞轮、手轮、及齿轮等键槽,往往用鉝床来代替铡床工作;因鉝床有操作简便、节约工作时间、及一次能完成所需要切削的形状等忧点。 鉝刀的制造颇为繁重;在制造时最感艰难者,为淬火后鉝刀每易弯曲,磨至平直时甚为费时。同时鉝刀本身较长,淬火设备较差的工厂,无法淬高速钢所制造的鉝刀。在此情况下,可以采用插入齿的方法来代替。现在将我们采用这个方法的经过及经验介绍如下,並希读者加以指正。第一种插入齿式如〔图一〕所示,鉝刀齿为二齿一连,鉝刀桿为圆往形,桿上铣一长槽,鉝刀齿嵌 In a large number of manufacturing plants, a variety of flywheels, handwheels, gears and other keyway, often with a bed instead of a bed work; because of the bed is easy to operate, save time and can be done once the required cutting shape Worry Trowel manufacturing is quite heavy; in the manufacture of the most difficult people, after quenching trowel each easy to bend, when it is very time-consuming to grind straight. At the same time trowel itself longer, harder equipment, poor factory, can not quench the high-speed steel manufactured trowel. In this case, the method of inserting the tooth can be used instead. Now we will use the method of experience and experience introduced below, and hope readers correct it. The first type of insertion as shown in Figure 1 〔〕 鉝, 鉝 teeth for the bidentate, 鉝 cutter bar for the round-shaped, rod milling a long groove, trowel embedded
