在大批量生产中,为了提高生产效率和保证零件的互换性,磨加工时需要采用成形磨削工艺。同时,由于高效率磨削工艺和少无切削工艺的发展,使许多零件可以不经车、铣等粗加工而直接采用磨削来达到技术要求。所以,发展成形磨削工艺是提高生产率和提高工件质量的当务之急。一、成形磨削概况1.成形磨削的几种方法成形磨削有下列几种:(1)成形砂轮磨削;(2)工件或砂轮作轨迹运动的成形磨削;(3)数控成形磨削……。第一种方法具有生产效率高、成本低、工件质量稳定、零件互换性好和工艺简单等优点,因此,在大批量生产中,它是最有发展前途的一种成形磨削。2.修整砂轮的方法成形磨削的关键是解决砂轮的成形修整。目前大
In mass production, in order to improve production efficiency and ensure the interchangeability of parts, grinding process requires the use of forming grinding process. At the same time, due to the high efficiency of grinding technology and the development of less non-cutting technology, many parts can be directly routed without grinding, milling and other rough to meet the technical requirements. Therefore, the development of forming grinding process is to improve productivity and improve the quality of the workpiece the top priority. First, the shape grinding Overview 1. Several methods of forming grinding Shaping the following types of grinding: (1) forming grinding wheel; (2) workpiece or grinding wheel for forming grinding; (3) CNC forming Grinding .... The first method has the advantages of high production efficiency, low cost, stable quality of the workpiece, good interchangeability of components and simple process. Therefore, it is the most promising form grinding in mass production. 2 dressing wheel method Shaping the key is to solve the grinding wheel forming trimming. Currently large
