问:氮化硅做切削刀具,它的几何形状和切削用量如何选择?何处有供应?答:热压氮化硅材料由于基体硬度高、抗弯强度大、热稳定性好,因而是作为刀具的好材料。上海电器陶瓷厂可以供应这种材料。电陶厂和清华大学等单位对热压氮化硅刀片做了一些切削试验工作。现以外圆车刀为例,简单介绍一下刀具几何形状和切削用量。 Q: Silicon nitride cutting tools, its geometry and cutting dosage how to choose? Where is the supply? A: The hot pressed silicon nitride material due to the matrix hardness, bending strength, thermal stability, and therefore as a Good tool for the material. Shanghai Electric Ceramics Factory can supply this material. Electric Pottery Plant and Tsinghua University and other units of the hot-pressed silicon nitride blades made some cutting test work. Now a turning tool, for example, a brief introduction to the geometry and cutting tool.
