为提高切入式专用曲轴磨床的生产效率和加工精度,一般该类磨床都有自动的砂轮圆弧修整器。这种修整器有单颗粒金刚石,成形滚轮和仿形三种形式。曲轴磨床的砂轮修整器近年来有较大发展,目前采用较多的是仿形修整器,根据其结构又可分为刀片、卧轴滚轮和立轴滚轮三种。这三种仿形修整器不仅在结构上有许多相似之处,而且动作原理相同,修整工具都是按仿形样板运动,修整后的砂轮形状也都取决于仿形运动的精度。与单颗粒金刚石修整器相比,仿形修整器的工作精度高,调整所需的辅助时间少,单件的工具消耗费也较低。因此,仿形修整器近年来得到了应有的重视。国外有的厂商已可根据不同的使用场
In order to improve the production efficiency and machining accuracy of the special crankshaft grinding machine, there are automatic grinding wheel arc dressers. This dresser has a single grain diamond, forming roller and contouring three forms. In recent years, there has been a great development of the wheel dresser for crankshaft grinding machines. At present, more profile dressers are used, which can be divided into three kinds of blades, horizontal axis rollers and vertical axis rollers according to the structure. These three profiling dressers not only have many similarities in structure, but also operate in the same principle. The dressing tools are all moved according to the profiling template. The shape of the finished grinding wheel also depends on the precision of the profiling movement. Compared with the single-grain diamond dresser, profiling dresser with high precision, less auxiliary time required for adjustment, and lower cost per tool. Therefore, profiling dresser has gained due attention in recent years. Some foreign manufacturers have different fields of use
