在机械加工中,对于深盲孔键槽的切制一直是个难题,而小盲孔,困难更大。我厂在加工孔径为φ14D、键槽长为100毫米、深1.6毫米、宽4毫米的小盲孔键槽时,用一般插刀杆加工,刚性差,切削时易滑刀或扎刀,加工质量差,为此,设计制作了一种深盲孔键槽插刀,经使用效果较好。刀具结构如图所示。使用时,将刀杆6夹持在插床上,以刀杆90°两侧母线调中心,并垂直于工作台面。调工作台使工件孔中心线与刀杆中
In the machining, the keyhole for deep blind hole cutting has been a problem, and the small blind hole, more difficult. I plant processing aperture φ14D, the keyway length of 100 mm, 1.6 mm deep, 4 mm wide blind hole keyway, the general insert bar processing, poor rigidity, cutting easy to slide or tie blade, poor processing quality To this end, the design made a deep blind hole key slot knife, the use of better. Tool structure as shown. When in use, clamp the arbor 6 on the slot machine, adjust the bus bar centering on both sides of the arbor 90 °, and perpendicular to the work surface. Adjust the work table so that the workpiece hole centerline and the arbor
