我厂某零件的一端有一窄槽,原用高速钢刀切制,由于该窄槽尺寸公差要求较严(1.1±0.05),用手工磨刀不易控制,精度较难保证,槽底常呈圆弧形。且切槽刀容易磨损,要经常刃磨,切槽刀重装上后,其轴向和径向定位位置均要重新调节,辅助工时多。为此,我们采用锯片铣刀在车床上进行切槽。其专用刀架结构如图所示。采用φ60x1.2mm细齿铣 I plant a part of a narrow slot at one end, the original high-speed steel knife cut, due to the narrow groove size tolerance requirements more stringent (1.1 ± 0.05), manual sharpening difficult to control, the accuracy is more difficult to ensure that the bottom of the tank often Round arc. And slotting knife easy to wear, to regular sharpening, grooving knife heavy equipment, the axial and radial positioning position must be re-adjusted, and more auxiliary work hours. For this purpose, we use a saw blade to cut the lathe. Its special tool holder structure as shown. Φ60x1.2mm fine tooth milling
