在汽车和拖拉机制造工业中,渐伸线拉刀已被广泛地运用。而制造这种拉刀,除了像一般拉刀一样,要保证材料、热处理条件、和刀磨质量外,还要保证下面两个条件:(1)渐伸线齿形误差底该在规定的公差范围内。(2)齿形分度误差应该满足拉刀的要求。渐伸线齿形是用成形砂轮磨出来的,因此成形砂轮的正确度就决定了渐伸线齿形的精度;所以砂轮的修正工作在渐伸线拉刀的制造过程中,
In the automotive and tractor manufacturing industries, involute broach has been widely used. The manufacture of this broach, in addition to general broaches, to ensure that the material, heat treatment conditions, and the quality of the knife, but also to ensure that the following two conditions: (1) involute tooth bottom of the error in the specified tolerance Range. (2) tooth indexing error should meet the broach requirements. The involute line tooth shape is formed by the grinding wheel, so the accuracy of the forming wheel determines the accuracy of the involute line tooth shape; therefore, the grinding wheel correction work is in the manufacturing process of the involute line broach,
