福特公司的这些柴油机缸体、缸盖加工自动线,有一个显著的特点,就是采用了400个可程控的伺服滑台。生产实践表明:它提高了生产率和可靠性,减少了维修,并具有相当的柔性。两年多以前,由于采用了这些伺服机构,代替了进刀箱、限位开关和控制进刀运动的液压缸,与改变皮带、皮带轮和齿轮这些方法相比,不仅使进刀速率和加工深度的控制 One of the distinguishing features of Ford’s diesel engine block and cylinder head machining automation line is the use of 400 programmable servo-sliders. Production practice shows that it increases productivity and reliability, reduces maintenance, and is reasonably flexible. More than two years ago, thanks to these servos, instead of the infeed case, the limit switches and the hydraulic cylinders that control the infeed movement, compared to changing belts, pulleys and gears, not only did the infeed rate and working depth control
