性能特点： 选用两台WY67Y系列同规格主机，配置双机联动同步装置。两台机床联动可加工特长工件。两台机床还可以同时单独使用，提高生产效率，配有挠度补偿机构。同步机构采用机液伺服和机械挡块。上滑块行程和后挡料架位置采用机动快速调节，手动微调，电子数控显示。 Features Two WF67Y series in same sepecification are chosen as main machine with double motor linkage synchro-device,which may work together to process overlong workpiece or operate separately to incerase production efficiency.Defection copensation device is fifted ,too. Meachanic and fluid servos with meachanic slider are utilized in synchronous device. The stroke of upper slider and the position of rear apron are regulated quickly by machine and miro-regulated quickly by machine and micro-regulated by hand with electronic NC display.
