Improve the comprehensive quality of operation personnelThe use of the nc machine tool is bigger than the difficulty of using ordinary machine tool, because the numerical control machine tool is a typical electromechanical integration products, it involves a wide range of knowledge, namely the operator should have machine, electricity, liquid, gas and other broader professional knowledge;Again, because of its electric control system of CNC system upgrade, the upgrade is faster, if not regularly attend professional theory training and study, are not fluent in the new CNC system applications.Therefore put forward to operating personnel's quality requirements are very high.Therefore, must carry on the training for CNC operators, make its principle, performance, lubrication part and way of nc machine tools, to systematically study and lay a foundation for better use of machine tools.At the same time in terms of the use and management of nc machine tools, formulated a series of practical and effective measures.For the use of the nc machine tools to create a good environmentBecause of nc machine tools is contained in a large number of electronic components, they are most afraid of direct sunlight, also afraid of moisture and dust, vibration, etc, these all can make the electronic components from corrosion bad or cause short circuit between the components, cause the machine doesn't run properly.Therefore, the use of nc machine tool environment should be kept clean, dry, constant temperature and no vibration;For the power supply voltage shall be maintained, generally only allowed plus or minus 10%.Strictly follow the correct proceduresNo matter what type of nc machine tools, it has its own set of operating rules, it is one of the important measures to ensure operator safety, and ensure the safety of the equipment, the use of product quality and other important measures.Therefore, users must, in accordance with procedures correct operation, if the machine in use or not for a long time for the first time, should first make it idle for a few minutes.And pay special attention to the use of attention to the order of the start-up, shutdown and matters needing attention.A, safe operation:1. CNC milling machine is a sophisticated equipment, so need to be armed to the operation of the CNC milling machine (a person, machine, create positions);2. The operator must be trained and proficient in operating, non-professional workers do not move;3. Have to confirm everything is ok before operation, then the clamping workpiece.Second, the daily maintenance and maintenance:1. The operator at the end of each processing, should clean the scattered working platform, guides and chip, oil dirties;Before the end of the work, should will stop after each servo axis to return to the origin;2. Check the oil amount is in line with the requirements of the lubricating oil tank.The manual go points, according to the rules go;3. Observe the machine guideway and screw surface presence of lubricating oil, keep the good lubrication;4. Check the workings of the hydraulic clamp, the workings of the main shaft; 5. Observe the conditions of the devolop in work, cutting fluid system work is normal, the devolop serious should stop cleaning;6. If leave the machine for a long time to turn the power off, in case of non-professional operation.Third, the weekly maintenance and maintenance:1. To thoroughly clean the machine every week.The guide surface and slip surface and the screw filling lubricating oil;2. Review and adjust the belt, pressure plate and strip the consistence;3. Check and twisted sliding block is fixed screw, feeding transmission mechanism, the handwheel, workbench bracket screw, wire;4. Check whether the filter is clean, if is dirty, must wash;5. Check the electric cabinet filter, clean the adhesion of dust.Four, the monthly and quarterly maintenance:1. Check the oil pipe to clear, bright window, and check the presence of sediment tank;2. Internal chip, oil dirties cleaning machine;3. All lubricating points come on; 4. Check all the transmission part whether is loose, check the status of gear and rack joint, when it is necessary to adjust or change;5. Check the high voltage cabinet and operating platform, the fastening screw is loose, use cleaner or cleaning dust contained in the blower.Check whether the terminal is loose (see electrical manual);6. Check all button and select the performance of the switch, the contact point is good, no leakage, damage to the replacement.Five, the annual maintenance:1. Check the ball screw, the screw on the old grease, change new grease;2. Replace the X, Z axis feed section of the bearing grease, replacement, be sure to clean the bearing;3. Cleaning all kinds of valves, filters, the tank bottom, in accordance with the provisions, an oil change;4. The main shaft lubrication box clean, replace lubricating oil;5. Check the motor commutator surface, deburring, blow net carbon powder, excessive wear of carbon brush replacement in time;6. Adjust the motor belt tightness;7. Cleaning clutch plate, the cooling tank and replace the coolant, replacement of cooling oil pump filter.
