一、概述传统机床加工机械零件,主要由机床的传动丝杠来保证其精度,也可称之为丝杠副的精度。对分度加工,是依靠蜗轮副的精度来保证。如加工阶梯多的轴类零件,有时由于操作不当,再加上丝杠精度的影响,往往不易保证零件精度,还容易出差错造成零件的报废,而且零件的尺寸在加工后才能用量具和仪器测量得知,这是一种被动测量。如果在车床、磨床、铣床、齿轮加工机床、螺纹磨床,以及坐标镗床等机床导轨附近或者在测量工具上,装上一套数显装置,即可在加工过程中,不断显示出零 First, an overview of traditional machine tool machining parts, mainly by the transmission screw machine to ensure its accuracy, but also can be called the accuracy of the screw pair. The division of processing, is to rely on the accuracy of the worm gear to ensure. Such as the processing of multi-axis shaft parts, and sometimes due to improper operation, coupled with the accuracy of the screw, often not easy to ensure the accuracy of the parts, but also prone to errors caused by the scrap parts, and the size of the parts can be used in the processing of measuring instruments and equipment Measured that this is a passive measurement. If the lathe, grinder, milling machine, gear processing machine tools, thread grinders, and coordinate boring machine tool rail or in the vicinity of measuring tools, equipped with a digital display device, you can continue to show in the process of zero
