我国的模具,无论是在寿命、制造周期,还是在模具本身精度和制造成本等方面都还比较落后。造成这种局面的因素固然很多,但是模具钳工的技术水平偏低也是重要环节之一。 本人根据多年从事工模具设计制造的体会和广泛的社会调查认为,近年来由于新工 China’s mold, both in life expectancy, manufacturing cycle, or in the mold itself, precision and manufacturing costs are still relatively backward. Although there are many factors that cause this situation, the low technical level of the fitter is also one of the important aspects. According to my experience in mold design and manufacture for many years and extensive social survey that in recent years due to new workers
