选择凿岩机零件材料,必须从下列基本前提出发: 使用——材料应适合矿山机械的工作条件; 工艺——材料应符合零件加工中省力的要求; 经济——零件的整个成本,除了材料的价格以外,还包括生产中的全部消耗,从零件的整个成本来看,材料应是经济有利的。因此,有根据地选择零件材料,是个复杂的技术经济问题。解决这一问题的困难还
The selection of rock drill part material must be based on the following basic prerequisites: Use - The material shall be suitable for the working conditions of the mining machinery; Process - The material shall meet the labor-saving requirements of the part machining; Economic - The total cost of the part, except the price of the material , But also the total consumption of production, the entire cost of the parts from the point of view, the material should be economically beneficial. Therefore, it is a complicated technical and economic issue to select the parts materials base by area. The difficulty of solving this problem also
