采用这种经研磨的硬质合金铰刀(图1)在有色金属和合金)其中有锡铅青铜)毛坯上加工精密孔,可提高被加工的表面质量、生产率和降低加工成本.此铰刀由BK 6M 制造的整体工作部份1,及45号钢或40X(HRC40—50)制造的刀柄2组成的.饺刀的工作部份毛坯(图2a)与刀柄毛坯(图2δ)用62焊料焊接.饺削时由于切削力和温度的关系不大,所以其他牌号的焊料以及环氧树脂等均可使用.再以饺刀工作部份的一端进行定位,磨削其刀柄和颈部,然后开刃.砂轮的形状,特性以及刃磨规范如表所示在2A135型立式钻床上,用此饺刀,并注入冷却液)50%的煤油和50%的20号工业油)加工孔径为13毫米及长度为65毫米的孔.将铰刀紧固在活动夹头上.当切削速度为0.17—0.21秒/米,进刀量为0.2—0.4毫米/转和保持切削深度为0.05毫米
Using this ground carbide reamer (Figure 1), precision holes are machined in blanks of non-ferrous metals and alloys, including tin-lead bronze, to improve surface quality, productivity and processing costs. BK 6M manufactured by the overall work part 1, and 45 or 40X (40C 40C (HRC40-50) made of handle 2. The working part of the dumpling blank (Figure 2a) and the handle blank (Figure 2δ) with 62 solder welding dumpling cutting temperature and temperature due to the relationship between the other grades of solder and epoxy resin can be used and then one part of the working part of the dumpling positioning, grinding its shank and neck And then edged. The shape, characteristics and sharpening specifications of the grinding wheel are shown in the table on the 2A135 vertical drilling machine, with this knife and with coolant) 50% kerosene and 50% industrial oil No. 20) A hole with a hole diameter of 13 mm and a length of 65 mm was machined.The reamer was fastened to the movable chuck.When the cutting speed was 0.17-0.21 s / m, the infeed amount was 0.2-0.4 mm / rev and the cutting depth was maintained at 0.05 mm
