目前我国硬质合金比较缺乏,要购买合乎刀具要求的几何形状的刀片,很成问题。而硬质合金又具有较高的硬度,要把它切割成所要求的几何形状,亦颇困难。这问题可用电蚀切割获得解决。一、设备及操作电蚀切割的设备如[图一]所示,它包括下列的主要部件:(1)锯盘——[图一]中的8,尺寸见[图二]。由Cr5号钢制成 At present, China’s relatively lack of cemented carbide, to meet the requirements of the tool geometry of the blade, is a problem. The cemented carbide has a higher hardness, it is necessary to cut it into the desired geometry, but also quite difficult. This problem can be solved using galvanic cutting. First, the equipment and operation Electro-erosion cutting equipment as shown in Figure 1, which includes the following main components: (1) saw - [Figure 1] 8, the size see [Figure 2]. Made of Cr5 steel
