小型成型磨齿机主题设计+CAD图纸
本毕业论文首先介绍了目前中国磨削技术发展的现状，阐明了本课题的研究目的和意义。在总结和借鉴各种国内外数控磨齿机的基础上，设计出了本次方案。
数控成形砂轮磨齿机是一种适用于高精度齿轮批量磨削加工的精密数控机床。其加工原理为成形法磨削，即将砂轮轴截面截形修整为与齿轮齿槽相对应的截面，进行成形磨削加工。磨削效率高，齿形精度高、可磨削齿数不限（无根切现象）、机床操作简单、运行可靠等优点，特别适用于对齿形有修形要求、齿向有鼓形要求及齿根、齿顶过渡部分有特殊要求的高精度、硬齿面直齿及螺旋齿圆柱齿轮的磨削加工。

The Design of The Forming Gear Grinding Machine
Abstract：With the gradual development of NC technology in mechanical field, began to gradually replace the traditional gear grinding machine grinding machine molding. This article is the study of NC dresser and CNC piding head, servo motor system is a core component of grinder NC, its performance directly affects the dimensional accuracy and surface roughness of grinding machining. This paper first introduces the current situation of the development of grinding technology China, expounds the purpose and significance of the research topic. Based on summarizing and referring to various domestic and foreign CNC gear grinding machine, designed the scheme. CNC gear form grinding machine is a kind of suitable precision CNC machine tools in the high precision gear batch grinding. The machining principle of forming grinding, the grinding wheel axial section profile modification for section corresponds with the gear tooth, forming grinding. High grinding efficiency, tooth profile precision, grinding teeth number does not limit (no undercut), the advantages of simple operation, reliable running machine, particularly applicable to the tooth profile modification requirements, a tooth to a drum shape and tooth, tooth top transition part with high precision, the special requirements of the straight tooth grinding teeth and helical gears.
Key Words： NC dresser, NC indexing mechanism , Molding method
