我厂加工的三齿链轮齿块(图1),要求粗加工的两侧面是分开加工完成的,生产效率比较低。为此我们自行设计了一种专用机床,一次走刀可同时加工完两侧面,提高了生产效率。为节约制造费用,降低消耗,使用了工厂仓库积压的动力头等部件。图11　专机结构　　自制机床的结构见图2。铣头 I plant processing three-tooth sprocket block (Figure 1), requiring roughing the two sides are separately processed, the production efficiency is relatively low. To this end, we have designed a special machine, a pass can be processed at the same time on both sides, to improve production efficiency. In order to save manufacturing costs, reduce consumption, using the first-class factory backlog of power components. Figure 11 plane structure Homemade machine structure shown in Figure 2.
