锯床液压传动系统由泵、阀、油缸、油箱、管路等元辅件组成的液压回路，在电气控制下完成锯梁的升降，工件的夹紧。通过调速阀可实行进给速度的无级调速，达到对不同材质工件的锯切需要。电气控制系统由电气箱、控制箱、接线盒、行程开关、电磁铁等组成的控制回路，用来控制锯条的回转、锯梁的升降、工件的夹紧等，使之按一定的工作程序来实现正常切削循环。
润滑系统开车前必须按机床润滑部位（钢丝刷轴、蜗轮箱、主动轴承座、蜗杆轴承、升降油缸上下轴、活动虎钳滑动面夹紧丝杆）要求加油。蜗轮箱内的蜗轮、蜗杆采用30号机油油浴润滑，由蜗轮箱上部的油塞孔注入，箱面备有油标，当锯梁位于最低位置时，油面应位于油标的上、下限之间。试用一个月后应换油，以后每隔3－6个月换油1次，蜗轮箱下部设有放油塞。
锯床锯条传动安装在蜗轮箱上的电动机通过皮带轮，三角胶带驱动蜗轮箱内的蜗杆和蜗轮，带动主动轮旋转，再驱动绕在主动被动轮缘上的锯条进行切削回转运动。锯条进给运动由升降油缸和调速阀组成的液压循环系统，控制锯梁下降速度从而控制锯条的进给（无级调速）运动。锯刷旋转在锯条出屑的地方，并随着锯床锯条走锯的方向旋转，并由冷却泵供冷却液清洗，清除锯齿上的切屑。冷却液在底座的右侧冷却切削液箱里，由水泵直接驱动供冷却液。

系统的模拟输入输出模块，使锯削过程的监控具有广泛的意义，如：锯床只要增加锯条变形的反馈，即可对锯削速度进行自适应调整。增加伺服阀，即可对锯削过程的速度和位置控制进行优化。系统的管理功能使材料和工件的管理更方便。系统的中文界面和实时的图形状态显示，使操作更友好更直观。
The hydraulic transmission system of sawing machine is composed of pump, valve, oil cylinder, oil tank, pipeline and other auxiliary parts. The lifting of saw beam and clamping of workpiece are completed under electrical control. The stepless speed regulation of feed speed can be realized through the speed regulating valve, so as to meet the sawing needs of different materials. The electric control system consists of electric box, control box, junction box, travel switch, electromagnet, etc. it is used to control the rotation of saw blade, lifting of saw beam, clamping of workpiece, etc., so as to realize normal cutting cycle according to certain working procedures. Before the start-up of the lubrication system, the lubricating parts of the machine tool (wire brush shaft, worm gear box, driving bearing seat, worm bearing, upper and lower shafts of lifting cylinder, clamping screw rod of sliding surface of movable vice) must be lubricated. The worm gear and worm in the worm gear box are lubricated with No. 30 oil bath. The oil is injected through the oil plug hole on the upper part of the worm gear box. There is an oil mark on the box surface. When the saw beam is at the lowest position, the oil level should be between the upper and lower limits of the oil level. The oil should be changed after one month of trial, and then every 3-6 months. The lower part of worm gear box is equipped with oil drain plug. The saw blade drives the motor installed on the worm gear box through the belt pulley and V-belt to drive the worm and worm gear in the worm gear box to drive the driving wheel to rotate, and then drive the saw blade around the active / passive flange for cutting and rotating. The feed motion of saw blade is composed of lifting cylinder and speed regulating valve, which controls the descending speed of saw beam and thus controls the feed (stepless speed regulation) movement of saw blade. The saw brush rotates at the place where the saw blade comes out of chips, and rotates along with the saw blade of the saw machine in the direction of sawing, and the coolant is supplied by the cooling pump to clean the chips on the saw teeth. The coolant is in the coolant tank on the right side of the base and is directly driven by the water pump to supply coolant. Press the emergency stop (stop) button and rotate clockwise. The oil pump motor works and the gear pump works. The oil enters the pipeline through the filter screen. Adjust the relief valve to make the system working pressure meet the requirements. Otherwise, press the button inward, all motors stop working. Press the clamp button to clamp the workpiece, the solenoid valve works, the hydraulic oil enters the left side of the clamping cylinder, the right side hydraulic oil returns to the oil tank, and the left clamp clamps the workpiece. When the saw beam of the sawing machine is lowered, press the working clamp, and the hydraulic oil enters the rod chamber of the lifting cylinder through the solenoid valve; the hydraulic oil in the rod free chamber flows through the solenoid valve, and the one-way speed regulating valve returns to the oil tank. When the saw beam is lowered quickly, the hydraulic pressure works through the solenoid valve. The oil enters the rod cavity of the lifting cylinder, and the oil in the non rod chamber returns to the oil tank through the solenoid valve. When the saw beam rises, press the up button, and the hydraulic oil enters the rod less chamber of the lifting cylinder through the solenoid valve; the oil in the rod chamber returns to the oil tank through the solenoid valve. When the workpiece is released, press the clamp release button, and the hydraulic oil enters the right side of the clamping cylinder through the solenoid valve; the left hydraulic oil can return to the oil tank through the solenoid valve, and the left jaw moves to the left, and the workpiece is released. The analog input and output module of the system makes the monitoring of sawing process have a wide range of significance. For example, as long as the feedback of saw blade deformation is increased, the sawing speed can be adjusted adaptively. The speed and position control of sawing process can be optimized by adding servo valve. The management function of the system makes the management of materials and workpieces more convenient. The Chinese interface and real-time graphical state display of the system make the operation more friendly and intuitive.
