在加工外径为150_(-0.05)~0、内径80_0~(+0.05)、厚度1.5毫米的胶皮垫圈,往往按常规车刀车削很难成型,会造成胶皮垫圈卷起而报废。我们经反复试切,选用直径为1毫米的废复合中心钻,在砂轮上刃磨,成为加工胶皮垫圈的车刀(见图),其加工使用方法如下: 1.将φ1毫米废复合中心钻刃磨成车刀,刀尖角为5°～7°及R1.5。磨好后必须用油石背光刀面至Ra=0.8微米,保证刀具切削锋
In the processing of outer diameter of 150 _ (- 0.05) ~ 0, diameter 80_0 ~ (+0.05), thickness 1.5 mm rubber gaskets, turning lathe is often difficult to shape by conventional turning, will cause the rubber gasket rolled up and scrapped. After repeated trial cutting, we selected waste compound center drills 1 mm in diameter to sharpen the grinding wheel to become the turning tool for processing the rubber gasket (see photo). The machining method is as follows: 1. Put the φ1 mm waste compound center drill Sharpening into turning tools, the tip angle of 5 ° ~ 7 ° and R1.5. Grind well must use whetstone backlit surface to Ra = 0.8 microns, to ensure that the tool cutting front
