大型工件的大平面精加工是重型机械、造船、冶矿机械等行业机械加工中急待解决的课题。我厂在生产实践中,原来常用的硬质合金刀片不重磨式端铣刀盘,在精加工大型平面时,很难满足对于尺寸、形位精度和光洁度要求较高的工件的加工。 1982年初,我厂承接了某船厂的大型机座的精加工任务。在TPM-3521龙门铣床上,使用了引进的端铣刀精加工11000mm×3000mm大平面,加工后,全面积不平度最大偏差仅为0.13mm,光洁度稳定在▽6～▽7,铣削性能很好。为解决大平面的精密加工,我们吸取了国外的先进经验,参阅了有关资料,经过一段时间的实践摸索,设计和研制了SF-1型大平面精密加工用高效低耗端铣刀(以下简称高精端
Large-scale large-scale workpiece finishing is heavy machinery, shipbuilding, metallurgical machinery and other industries machining urgent problem to be solved. I plant in the production practice, the original common carbide inserts do not wear end milling cutter plate, in the finishing large plane, it is difficult to meet the requirements for size, shape accuracy and finish of the workpiece processing requirements. In early 1982, I plant to undertake the finishing of a large shipyard’s finishing tasks. In the TPM-3521 gantry milling machine, using the imported end mill finishing 11000mm × 3000mm large plane, after processing, the maximum overall unevenness of roughness is only 0.13mm, smooth finish stable at ▽ 6 ~ ▽ 7, milling performance is very good . In order to solve the large-scale precision machining, we have learned advanced foreign experience, refer to the relevant information, after a period of practice to explore, design and development of SF-1 large flat surface machining with high efficiency and low consumption end mill (hereinafter referred to as High-end
