使用陶瓷刀具加工的零件和工序类别主要有:刹车鼓制动面的精搪、半精搪,连杆大、小头孔的精搪、半精搪、半轴套管淬火后的精车和缸体的缸孔及缸套孔的精搪等。1.日野汽车公司的刹车鼓(粗车制动面,内径φ405mm,宽225mm,灰铸铁 Fe25+Cu、Ni)生产线,原用硬质合金刀具,切削速度为65～100m/min,拍节3.5min。改用金属陶瓷多刀刀头刀具,切削速度提高到80～300m/min,拍节缩短为2min,提高效率43%。工具寿命保证值为刀片每个角加3224件(以连续工作60分钟计算),取得了很好的效果。
The use of ceramic cutting tools and processes are the main categories of components: Brake brake surface of the fine enamel, semi-fine enamel, connecting rod, small hole fine enamel, semi-fine enamel, semi-shaft casing after quenching fine car and Cylinder cylinder bore and cylinder bore fine enamel and so on. 1. Hino Motors brake drum (rough braking surface, the inner diameter φ405mm, width 225mm, gray cast iron Fe25 + Cu, Ni) production line, the original carbide cutting tools, cutting speed of 65 ~ 100m / min, beat Festival 3.5 min. Use of metal ceramic multi-knife tool, cutting speed increased to 80 ~ 300m / min, beat section shortened to 2min, improve the efficiency of 43%. Tool life guarantee value for each blade angle plus 3224 pieces (60 minutes of continuous work), and achieved good results.
