我厂制造的某产品上,有一种工字链板,两端有 R22的圆弧,需要用圆弧样板铣刀来加工。这种样板铣刀的圆弧部分,过去是由铲床加工出来的,效率很低,并且质量很难达到要求。后来,工具车间铣工张秀同志,改进在万能铣床上用棒铣刀来加工,大大提高了工作效率,并保证了质量。改进后的加工方法如附图,在万能铣床的主轴孔内装上棒铣刀。工件(圆弧样板铣刀)装在特制的心轴上,一端用螺帽锁紧。这心轴的两端,根据工件的
I plant a product, there is a kind of word chain plate, both ends of the arc R22, you need to use circular arc milling cutter to process. The circular arc part of this model milling cutter, used to be machined from a shovel, is inefficient and difficult to meet the quality requirements. Later, the workshop tool mills Zhang Xiu comrades, improved on a universal milling machine with a bar cutter to process, greatly improving the work efficiency and ensure the quality. Improved processing methods as shown in the figure, in the universal milling spindle hole equipped with rod cutter. Workpiece (arc model cutter) mounted on a special mandrel, one end with a nut lock. This end of the mandrel, according to the workpiece
