Flammable and explosive materials shall not be placed near the deburring machine to prevent accidents caused by the discharge sparks caused by the temporary supply of working fluid. The operator must be familiar with the processing technology of the deburring machine, properly select the processing parameters, and operate according to the specified operation sequence to prevent failures such as broken wires.
The operator must be familiar with the operation technology of the deburring machine. Before starting the machine, oil should be injected into the relevant parts of the machine according to the lubrication requirements of the equipment (the lubricating oil must comply with the requirements of the machine manual).
Before the formal processing of the workpiece, it should be confirmed that the position of the workpiece has been installed correctly to prevent the collision of the wire frame and the excessive damage to the screw, nut and other transmission components. For workstations without over-range limits, over-range fall accidents should be prevented.
Try to eliminate the residual stress of the workpiece and prevent the workpiece from bursting and hurting people during cutting. The protective cover should be installed before processing.
When stopping, the high-frequency pulse power supply should be stopped first, and then the working liquid should be stopped, so that the electrode wire can run for a period of time, and then stop the wire after the reverse of the wire storage cylinder. After the end of the work, turn off the main power supply, wipe the table and fixture, and lubricate the machine. After handling the storage cylinder with the handle, the handle should be pulled out in time to prevent the handle from being thrown out when the storage cylinder is rotating. When loading and unloading the electrode wire, pay attention to prevent the electrode wire from sticking your hands. The replaced wire should be placed in the specified container to prevent mixing into the circuit and wire system, causing electrical short circuit, contact and broken wire accidents. Pay attention to prevent breakage of wire and collision of transmission parts due to inertia of wire cylinder. To this end, when stopping, press the "stop" button as soon as possible after the storage cylinder has just reversed.
Regularly check whether the protective grounding of the machine tool is reliable, pay attention to whether the parts are leaking, and try to use anti-electric shock light. After closing the processing power supply, do not touch the two output ends of the power supply (bed and workpiece) with hand-held conductive tools to prevent electric shock. Do not press the switch or touch the power supply with wet hands. Prevent working liquid and other conductive substances into the electrical part, once the electrical short circuit caused by fire, should first cut off the power supply, immediately use carbon tetrachloride and other appropriate fire extinguishers, do not use water to fight the fire. When overhauling machine tools, machine tool appliances, pulse power supplies, and control systems, attention should be paid to properly cut off the power supply to prevent electric shock and damage to circuit components.
