在车床上车削软、硬橡胶工件时,由于橡胶材料具有高弹性、高延伸率、低导热性,使工件很难达到加工精度和光洁度的要求。而采用车削、磨削两道工序时,效率低、成本高。为此,我厂在加工如图1所示工件,设计制造了套筒式橡胶车刀,其零件加工光洁度可达(?)6以上,生产效率比车-磨提高3～5倍。刀具特点:见图2所示。1.套筒式车刀采用85°前角,切削轻快;
When turning soft and hard rubber parts on a lathe, the rubber material has high elasticity, high elongation rate and low thermal conductivity, making it difficult for the workpiece to meet the processing precision and finish requirements. The use of turning, grinding two processes, low efficiency, high cost. To this end, I plant in the processing of the workpiece shown in Figure 1, designed and manufactured a sleeve-type rubber turning tool, the parts finish machining up (?) 6 above, the production efficiency than the car - grinding increased 3 to 5 times. Tool Features: See Figure 2 below. 1. Sleeve type lathe with 85 ° rake, cutting light;
