Double Column Horizontal Band Saw GH4240

The hydraulic transmission system is a hydraulic circuit composed of components such as pumps, valves, oil cylinders, oil tanks, pipelines, etc. It completes the lifting of the saw beam and the clamping of the workpiece under electrical control. The stepless speed control of feed rate can be achieved through the speed control valve to meet the cutting needs of different materials of workpieces.

The electrical control system consists of a control circuit consisting of an electrical box, control box, junction box, travel switch, electromagnet, etc. It is used to control the rotation of the saw blade, lifting of the saw beam, clamping of the workpiece, etc., to achieve normal cutting cycles according to a certain working program.

Before starting the lubrication system, oil must be added according to the requirements of the lubrication parts of the machine tool (wire brush shaft, worm gear box, active bearing seat, worm bearing, upper and lower shafts of the lifting oil cylinder, and clamping screw of the sliding surface of the movable vice). The worm gear and worm gear inside the worm gear box are lubricated with No. 30 engine oil bath, injected through the oil plug hole on the upper part of the worm gear box. The box surface is equipped with an oil mark. When the saw beam is in the lowest position, the oil level should be between the upper and lower limits of the oil mark. After one month of trial use, the oil should be changed, and then every 3-6 months. There is an oil drain plug at the bottom of the worm gear box.
