The hydraulic transmission system consists of a hydraulic circuit composed of pumps, valves, cylinders, oil tanks, pipelines, and other components. Under electrical control, it controls the raising and lowering of the saw beam and the clamping of the workpiece. The feed speed can be infinitely adjusted via a speed control valve to meet the sawing needs of workpieces of different materials. The electrical control system consists of a control circuit composed of an electrical box, control box, junction box, limit switches, electromagnets, etc., used to control the rotation of the saw blade, the raising and lowering of the saw beam, and the clamping of the workpiece, ensuring a normal cutting cycle according to a specific work procedure.
Before starting the machine, the lubrication system must be lubricated according to the requirements of the lubrication points (wire brush shaft, worm gear box, drive bearing housing, worm bearing, upper and lower shafts of the lifting cylinder, and sliding surface of the movable vise clamping screw). The worm gear and worm in the worm gear box are lubricated with No. 30 machine oil bath lubrication, injected through the oil plug hole at the top of the worm gear box. An oil level indicator is provided on the box surface; when the saw beam is in the lowest position, the oil level should be between the upper and lower limits of the indicator. The oil should be changed after one month of trial use, and then every 3-6 months thereafter. An oil drain plug is located at the bottom of the worm gear box.
The saw blade drive is powered by a motor mounted on the worm gear box, which drives the worm and worm wheel inside the box via a pulley and V-belt. This drives the drive wheel to rotate, which in turn drives the saw blade, wound around the rims of the drive and driven wheels, in a cutting rotational motion. The saw blade feed is controlled by a hydraulic circulation system consisting of a lifting cylinder and a speed control valve, which controls the descent speed of the saw beam and thus the saw blade feed (steplessly adjustable). The saw brush rotates at the chip removal point and follows the saw blade's cutting direction. A coolant pump supplies coolant to clean the brush, removing chips from the saw teeth. The coolant is located in a cutting fluid tank on the right side of the base and is directly supplied by a water pump.
