我们在解决小型卡板校对块的精密刻线工作中,采用下述装置挖制刻线深度。把装上划针的夹具(如图1)安装于显微镜的物镜头上,并用阶梯高度为10毫米的对块调整千分表的安装高度(如图2所示)旋转显微镜聚焦粗调手轮下降针尖,再旋转微调旋钮使针尖与对块表面接触(可 We are in the process of solving the problem of precision reticle calibration of small pallets, using the following device to dig the reticle depth. Fix the erected jig (Figure 1) on the objective lens of the microscope and adjust the mounting height of the indicator with a block height of 10 mm (as shown in Figure 2) Rotate the microscope to focus the coarse handwheel Lower the needle, and then turn the fine-tuning knob so that the tip touches the surface of the block
