我厂经常对零件进行刻字加工,原来使用的刻字铣刀,如图1所示。这种刻字铣刀,由于结构上的缺陷,强度低、易磨损,加工钢件困难。后来,经过改进,结构如图2所示,此种结构的刻字铣刀,克服了上述缺点,延长刀具寿命7倍多,并能加工钢件、铝件、铜件及其它非金属材料的工件。 I plant parts often lettering processing, the original lettering cutter, shown in Figure 1. This lettering cutter, due to structural defects, low strength, easy to wear, difficult to machine steel. Later, after the improvement, the structure shown in Figure 2, the lettering cutter of this structure to overcome the above shortcomings, to extend the tool life of more than 7 times, and can be processed steel, aluminum, copper and other non-metallic materials .
