超小型无綫电元件如组装半导体小型电位器結构用的各种焊片鉚釘、档釘、軸和軸套等金工零件,体积小,精度要求高、工艺复杂,在車床上进行一般車削,产量低、质量不高。我厂在大搞群众技术革新运动中,推广一种配合台式仪表車床用的組合刀架。附图是組合刀架的安装图。图中1是CO618型台式仪表車床上的方刀架,新刀架即装在該刀架上。6是新刀架的主体,在上端用两个螺釘7来固定鎖釘3,防止旋轉,并有两个M 8螺母一起装配在新刀架上。根据工件的結构尺寸,用专用磨刀砂輪和平面磨床,分别磨出加工工件用的外圓切刀、样板刀、切槽刀、
Ultra-small radio components such as the assembly of semiconductor miniature potentiometer structure with a variety of welding pads rivets, dowels, shafts and bushings and other metalworking parts, small size, high precision, complex technology, general turning in the lathe, the output Low, low quality. I plant in the masses of technological innovation campaign, to promote a combination of desktop instrument lathe with a combination of turret. Figure is a combination of tool holder installation diagram. The figure 1 is a square knife table on the CO618 table lathe, a new knife holder is mounted on the knife holder. 6 is the body of a new tool holder with two screws 7 on the top for securing the stud 3 against rotation and two M 8 nuts fitted together on the new tool holder. According to the size of the workpiece structure, with a special grinding wheel and surface grinding machine, respectively, grinding out of the workpiece with a cylindrical cutter, sample knife, grooving knife,
