苏联基辅机床制造生产联合公司在半精铣和粗铣结构钢零件的工序上采用了切向安装四边形机夹刀片的套式端铣刀(直径160mm,齿数10),刀片用无钨硬质合金KHT—16制造,刀片采用切向安置能大大增加其抗弯力矩,减少由于微裂纹而损坏刀片的可能性,从而提高刀具工作的可靠性。刀片的所有表面须用金刚石砂轮磨光,以保证它们在铣刀上有较高的装配精度和获得R_a=2.5～5μm的加工表面粗糙度。在万能卧式铣床,数控立式铣床和多用途数控机床上使用上述铣刀,铣削用量为:当加
Soviet Kiev Machine Tool Manufacturing and Production Associates employed a sleeve end mill (diameter 160 mm, number of teeth 10) tangentially mounted on a quadrilateral machine tool insert for semi-finish and rough-milled structural steel parts, a tungsten-free tungsten carbide insert KHT-16 manufacturing, blade tangential placement can greatly increase its bending moment, reduce the possibility of damage due to microcracks blade, thereby enhancing the reliability of the work tool. All surfaces of the blade shall be polished with diamond grinding wheels to ensure that they have a high degree of assembly accuracy on the milling cutter and a machined surface roughness of R_a = 2.5 to 5 μm. In the universal horizontal milling machine, CNC vertical milling machine and multi-purpose CNC machine tools using the above milling, milling dosage is: plus
