近一、二十年来,机床向着高精度、高转速、高生产率、自动化、低能耗、安全可靠的方向发展的趋势十分明显。机床产品要在国际市场具有足够的竞争能力,必须满足现代代生产和劳动组合的要求,因而对机床性能、精度和生产率提出了更高的要求。 六十年代初,日本成立了机械和金属检验 Nearly one or two decades, the machine toward the high-precision, high speed, high productivity, automation, low energy consumption, safe and reliable direction of the trend is obvious. Machine tool products in the international market to have sufficient competitiveness, must meet the modern generation and labor requirements of the portfolio, thus the machine performance, accuracy and productivity put forward higher requirements. In the early 1960s, Japan established mechanical and metal inspection
