在机械制造工业中广泛采用高效率的工艺方法来加工螺纹。其中外螺纹的加工主要是用搓丝及滚丝的方法,因此搓丝板成为一种重要的螺纹加工工具。目前,国内各厂用的搓丝板是由工具厂供应的,搓丝板在专用的液压平面仿形滚丝机上用反滚法制造而成。但是,搓丝板经用户使用磨损超限后,即告报废,造成浪费。搓丝板的价值为每付100元左右。最近,国内有些工厂已开始采用自制多线砂轮修复搓丝板,取得一定成效,现将此法简介如下:多线砂轮的制造多线砂轮在市场上无货供应,需要自制。可控机床的主轴结构使用双面凹砂轮,材质为刚玉,粒度为180～280。其基本原理是:在平面磨床上加一套工艺装备,先让砂轮低速转动和淬硬的滚轮对滚,微量进给,慢速滚挤,逐步将砂轮上的砂粒“啃”下来,使砂 In the machinery manufacturing industry widely used high-efficiency process to process the thread. One of the external thread processing is mainly the use of thread rolling and rolling method, so the thread rolling plate has become an important thread processing tools. At present, the domestic factory with the rolling plate is supplied by the tool factory, Roll plate in a special hydraulic plane profiling rolling machine made by the anti-roll method. However, the wear plate by the user wear out of limits, that scrapped, resulting in waste. Roll plate value of 100 yuan per visit. Recently, some domestic factories have begun to use homemade multi-line grinding wheel repair screw plate, and achieved some results, this method is as follows: Multi-line grinding wheel manufacturing Multi-line grinding wheel in the market no stock supply, need to make. Controllable spindle structure using double-sided concave wheel, made of corundum, particle size 180 ~ 280. The basic principle is: add a set of technology and equipment in the surface grinder, let the wheel rotate at low speed and hardened wheel on the roll, micro feed, slow roll squeeze, and gradually grinding wheel grit “down” to make sand
