選用兩臺WC67Y/WC67K/ZYB型同規格或不同規格（僅針對ZYB系列）主機，配置雙機聯動同步裝置。兩臺機床聯動可以加工特長工件，兩臺機床還可以同時單獨使用，提高生產效率，
配有撓度襯償機構。同步機構采用機液伺服和機械擋塊。上滑塊行程和后擋料架位置采用機動快速調節，手動微調，電子數控顯示。

　　Two WC67Y/WC67K/ZYB series in same specification or different specification(only for ZYB series)are choosen as main machine with double motor linckage synchro-device,
which may work together to process overlong workpiece or operate separately to increase production efficiency. Deflection compensationdevice is fitted too. Mechanic and fluid
servos with mechanic slider are utlized in synchronous device. The stroke of upper beam and the position of rear stopper are regulated quickly by machine and micro-regulated
by hａnd with electronic display o CNC controllers.
