为了在研制新牌号矿物陶瓷时选择合理的方案,以及为了预先确定其在工业生产中的合理使用范围,苏联曾以各种被加工材料在宽广的切削用量范围内对各种牌号的陶瓷刀片进行了纵向和横向车削试验。用50号钢(HB190—220)进行横向车削,以初步评定其切削性能。车削时应保证被加工材料具有最大限度的同一性,并对切削刃施加模拟的进、退刀负荷。这种方法可以比连续车削法在更大程度上检查陶瓷的使用强度。纵向车削时试验了同样的50号钢、灰铸铁和白口铁。确定了陶瓷刀片耐用度与切削速度和进给量的关系。在所有试验中几何参数保持不变,
In order to choose a reasonable solution for the development of new grades of mineral ceramics and to predetermine its reasonable scope of use in industrial production, the Soviet Union used a variety of materials to process various grades of ceramic blades over a wide range of cutting loads Longitudinal and transverse turning tests. Use the 50 steel (HB190-220) for horizontal turning to assess its cutting performance. Turning should ensure that the processed material has the greatest degree of identity, and the cutting edge to impose a simulation of the retractable load. This method can be used to check the strength of ceramics to a greater extent than the continuous turning method. Longitudinal turning tested the same 50 steel, gray cast iron and white iron. The relationship between the durability of the ceramic blade and the cutting speed and feed rate was confirmed. The geometric parameters remained unchanged in all experiments,
