随着航空产品性能的不断提高,随着新技术、新结构、新材料,新工艺的不断涌现,对机床提出更新更高的要求,迫使我们采用新机床、改造老机床,以满足产品更新换代的急需。据不完全统计,近三年来,我部已更新机床约二千多台,改造老机床一千多台,占机床拥有量的5％左右。数量虽少,但对保证新产品生产和提高老产品质量起到一定的作用,从中也取得一些值得借鉴的经验教训。现参照国外机床更新情况对航空工业机床更新的几个问题提出粗浅的看法。
With the continuous improvement of the performance of aviation products, with the continuous emergence of new technologies, new structures, new materials and new processes, new and higher requirements for machine tools are put forward, forcing us to adopt new machine tools and transform old machine tools to meet the requirements of product replacement Urgent need. According to incomplete statistics, in the recent three years, our ministry has updated about 2,000 machine tools and renovated more than 1,000 old machine tools, accounting for 5% of the total amount of machine tools. Although the quantity is small, it plays a certain role in ensuring the production of new products and improving the quality of old products, and also obtains some experiences and lessons worth learning from. Now refer to the situation of foreign machine tools to update the aviation industry machine several issues put forward a superficial view.
