1.数控机床发展概况 “产品多样化”和产品的更新快,是当前机械制造业的明显特点,因而多品种,中、小批量生产现在越来越占优势。即使以大批量生产著称的美国,加工批量在50件以下的也占75%。日本的中、小批量生产则高达80%。这就要求设备具备很大的灵活性。而新型产业如航空、宇
1. Overview of the development of CNC machine tools “Product diversification” and product updates fast, is the obvious characteristics of the current machinery manufacturing, multi-species, medium and small batch production is now more and more dominant. Even the United States, known for its mass production, accounts for 75% of all processing volumes below 50. Japan’s medium and small batch production is as high as 80%. This requires equipment with great flexibility. The new industries such as aviation, Yu
