Common faults ofbridge disc stone sawing machineare: the worktable can not rise, can not rotate left and right, the bed deviates during the cutting process, the feed of saw blade is out of control, the bed moves with abnormal sound or stuck, etc. In general, we can use flow chart analysis and troubleshooting.

　　Next let's talk about the maintenance and maintenance of ourbridgedisc stone sawingmachine.

　　1.Button box and electrical appliances

　　The button box which controls the turning and turning of the worktable will inevitably splash water when cutting the plate. Over time, it will cause the button contact rust. It is necessary to check regularly to remove the rust spots. The device uses 18 miniature relays in the PLC control system. The contact capacity is small and the action is frequent. As a result, the relay often has bad contact, so it should be checked or replaced in time. The replaced relay can generally be restored to use as long as the contact is removed and lightly polished. The plugs of solenoid valves will also have bad contact loosening failure, which should also be reproduced.

　　2. Lubricating Oil and Hydraulic Oil Pool

　　The rack support oil pools at both ends of the bed should be kept sealed and oil surface height. The V-shaped guide rail and rack of the cutter in the oil tank of the bed should also keep the oil level high, and the oil should be changed in time when the oil deteriorates or the water enters. The manual pump for the lubrication system of the lifting circular guide should be 30 Frequently observe the oil level of the moving reducer, the cutter reducer and the spindle oil window before and after the bed, and change the oil at least once a year.

　　For each lubrication point of the overturning shaft, the overturning cylinder support, the piston rod support shaft and the rotary gear transmission mechanism of the overturning table, lubricating oil or grease must be added once per shift. When the machine stops at the end of the work, the workbench must be raised so that the overturning mechanism can move once, avoid rust, and be conducive to the drying of the workbench and prevent the decay of the boards on it.
