我厂制造花键塞规时的主要技术条件如下: (1)周节误差不大於0.008公厘; (2)花键对中心线的错位不大於0.006公厘; (3)花键两侧对中心线的平行性不大於0.005公厘。 (4)定位直径的几何形状(锥度、椭圆性等)误差必须在直径的公差范围内(约0.007公厘)。 根据设备条件,最後的精加工是 The main technical requirements for the manufacture of spline plugs in our factory are as follows: (1) the error of the week is not more than 0.008 mm; (2) the misalignment of the splines to the centerline is not more than 0.006 mm; (3) The parallelism of the center line is not more than 0.005 mm. (4) The diameter of the positioning of the geometric shape (taper, elliptical, etc.) The error must be within the diameter tolerance (about 0.007 mm). According to the equipment conditions, the final finishing is
