下述数控机构(图1)可检测被加工孔的尺寸(借助珩磨头和标准环,图1中未示出),从而可自动补偿油石的磨损,核算机构的传动系统内间隙,且可简化机床为获得所需尺寸的调整。径向定量进给是由程序控制的,其不连续性用0.1 mm/min来测量。它与珩磨头每分钟往复移动的双行程次数无关。在壳体1(见图1)上配置有步进电机M1和反馈光控脉冲传感器BE。后者与CNC系统进行电和信息的联系。在壳体1内配置有齿轮z_1和齿轮z_2。前者通过离合器2与电机M1的轴连接,后者的轮毂通过控制杆
The following CNC mechanism (Fig. 1) can detect the size of the hole to be machined (by means of a honing head and a standard ring, not shown in Fig. 1) so as to automatically compensate for the wear of the whetstone, to account for the gap in the drivetrain of the mechanism and to simplify Machine to get the desired size adjustment. Radial dosing is program-controlled and its discontinuity is measured at 0.1 mm / min. It has nothing to do with the number of double strokes reciprocating the honing head per minute. The housing 1 (see FIG. 1) is provided with a stepping motor M1 and a feedback light control pulse sensor BE. The latter with the CNC system for electrical and information contact. In the housing 1, a gear z_1 and a gear z_2 are arranged. The former is connected to the shaft of the motor M1 through the clutch 2, and the latter passes the control rod
