切齿加工工艺中的多数场合,都是采用多刃精切刀具加工。主要采用铲齿滚刀,滚刀结构的基本原理是采用一种万能刀具用以加工同一模数各种不同齿数的齿形,然而,对于各种具体的加工场合,当必须考虑被加工材料的机械性能、对表面质量的要求,刀具材料、切削用量等条件时,要保证切削部分具有合理的几何形状是复杂的。新的高生产率机器的生产,首先是大功率稀有设备的生产、要提高采矿、治金、电力、运输和其他设备工作的耐久性和可靠性、减少制造时需要的劳动消耗量和周期,很大程度上都取决于加工大模数圆柱齿轮(齿形总长度达 Cutting gear cutting process in most cases, are using multi-blade cutting tool. The main use of shovel hob, Hob structure, the basic principle is to use a universal tool for processing the same modulus of different tooth number of teeth, however, for a variety of specific processing occasions, must consider the material to be processed Mechanical properties, surface quality requirements, tool materials, cutting conditions such as cutting, to ensure that the cutting part has a reasonable geometric shape is complex. The production of new high-productivity machines begins with the production of high-power, rare equipment to increase the durability and reliability of mining, metallurgy, power, transportation and other equipment work, and to reduce labor consumption and cycles required for manufacturing To a large extent depends on the processing of large modulus cylindrical gear (profile length up to
