我厂在加工专用于硬地层的硬质合金球齿牙轮钻头时,有27万粒4种规格的硬质合金球齿(材料YG11C)的外圆需经磨削,如按常规采用碳化硅砂轮磨削,无法完成任务,使用了人造金刚石砂轮显著地提高了生产效率,胜利完成了任务。采用人造金刚石砂轮后,由于磨削效率大大提高,靠手工一件件的装活,不能适应工作要求。为此,我们革新了送料装置(如附图),增添了工件道管
Our factory in the processing of hard alloy hard-alloy ball gear cone bit, there are 270,000 4 kinds of specifications of carbide ball (material YG11C) of the outer need to be grinding, such as the conventional use of silicon carbide Wheel grinding, unable to complete the task, the use of synthetic diamond grinding wheel markedly increased production efficiency, the victory to complete the task. After the use of artificial diamond grinding wheel, due to greatly improve the grinding efficiency, by hand a piece of work, can not meet the job requirements. To this end, we have revolutionized the feeding device (as shown in the attached drawings) and added the workpiece duct
