摘 要
随着科学技术的发展和社会的日益进步，对机械产品的可靠性和使用性能要求越来越高。高压容器尤其是核工业高压容器，由于其使用场合的特殊性，不仅要求对内外表面进行磨削加工，而且对封头焊缝和堆焊层提出了严格的要求。随着新型磨料砂带的诞生，传统的砂带磨削加工方法朝着精密和超精密的方向发展，砂带磨削不仅具有高效、冷态、低粗糙度等优点，而且在脆硬材料表面精密加工中表现出优良的磨削性能。
本文正是在这种背景下，从实际出发，结合数控技术和PLC逻辑控制技术，通过对核电封头加工工艺的分析，研制出基于西门子802D数控系统的数控核电封头磨挫机。磨挫机采用新型砂带磨削，彻底改变采用人工控制抛光核电封头的效率底、加工效果差的问题，

ABSTRACT
As the developing of the science technology and the progressing of the social Civilization, people have proposed high capability and reliability for the mechanical product. High-pressure vessel, especially the vessels used for Nuclear Industry, because of their special working situation, not only both the outside and the inside surface have to be ground, but also the welded joint of them should be handled strictly. As the invented of new grinding belt with effective abrasive grains, traditional belt grinding progress has been improved a lot. Now we can obtain a very satisfactory surface texture by belt grinding process. Belt grinding process is a very effective, low Processing temperature, high surface roughness process, which also performance very good in the Brittle material’s finishing operation.
This paper has been done based on this background. Through proceeding from reality and making an analysis of the proceeding process, we designed a numeric controlled belt grinding grinder base on SINUMERIK 802D system. The grinder is use in the vessel’s finishing process. This system integrates Numeric Control Technology and Programmable Logic Controller Technology. The belt grinding grinder, which is using the most advanced belt, has completely changed the low efficient and the low quality of the grinder controlled by workers.
