节省材料材料价格占钻头全部成本的比重是很大的。例如,高速钢的钻头,材料价格约占90%,合金钢钻头则占55%。由于钻头的大量生产及消耗大量的钢料,材料的节省问题就成了生产钻头的一个重要经济因素。制造钻头的新工艺方法是利用金属塑性变形的性质,这在节省材料方面是很有效果的;它可以得到钻头的形状而无需将金属以切屑的形态来切去,这是在旧的铣槽方法中所不能达到的。
Material saving material costs accounted for the total cost of the drill bit is very large. For example, high-speed steel drill bit, the material price of about 90%, alloy steel drill bit accounted for 55%. Due to the mass production of drill bits and the large amount of steel consumed, material savings have become an important economic factor in the production of drill bits. A new process for making bits is to take advantage of the plastic deformation of the metal, which is very effective in material saving; it can take the shape of the bit without cutting the metal in the form of chips, The method can not be achieved.
