许多机械设备常需设置检视窥窗而必须切制出或大或小的玻璃圆孔、图片，如没有合适的加工装置，则较为贫工费时，精度差、废品率高。在此介绍一种高效精确地加工玻璃圆孔、圆片的工具。1磨头与磨料用45铜加工一圈1所示的研磨头，D为可切出的圆孔的尺寸，d为可切出的圆片的尺寸 Many machinery and equipment often need to set the viewfinder window must be cut out large or small glass hole, picture, without the proper processing device, the more time-consuming, poor precision, high rejection rate. Here is a highly efficient and accurate processing of glass round hole, wafer tools. 1 grinding head and abrasive with 45 copper processing lap 1 shown, D is the size of the hole can be cut out, d is the size of the cut out of the wafer
