根据最新部标，K_0型合金片的几何结构及参数，如图1和表1所示。合金片几何参数的修改意见。一、合金片长度（L）合金片长度L，即钎头初径D_k。D_k可由下式确定：D_k=D_H+n·D_0（毫米）（1）式中：D_H——钎头终径（报废直径）（毫米）；n——钎头修磨次数（一般定为10～12次）；D_0——磨次直径损耗（毫米/次）；众所周知，钻速与钎头直径的平方成反比。为了提高打眼速度，希望D_k尽可能小些。但是，为了保证钎头有较长的寿命，为了提高合金片的利用率，n值又不能太低。在钎头质量提高，使用技术合理的条
According to the latest superscript, K_0-type alloy sheet geometry and parameters, shown in Figure 1 and Table 1 below. Modification of alloy sheet geometric parameters. First, the length of the alloy sheet (L) alloy piece length L, that is, the initial diameter of the drill D_k. D_k can be determined by the following formula: D_k = D_H + n · D_0 (mm) (1) Where: D_H - diameter of the drill tip (scrapped diameter) (mm); n-- sharpening the number of grinding ~ 12 times); D_0 - mill diameter loss (mm / time); it is well known that the drill speed is inversely proportional to the square of the diameter of the drill bit. In order to improve the speed of drilling, hope D_k as small as possible. However, in order to ensure that the drill bit has a longer life, in order to improve the utilization of the alloy sheet, the value of n can not be too low. Improve the quality of the drill head, the use of technology and reasonable article
