In modern manufacturing, the maintenance and maintenance of metal processing equipment is a key link to ensure production efficiency and product quality. Through reasonable maintenance strategies, enterprises can not only extend the service life of equipment, but also reduce operating costs, improve equipment reliability and production efficiency.
1. Regular inspection and maintenance plan
Daily maintenance:
Check the lubricating oil level to ensure machine lubrication.
Check whether there is enough coolant in the coolant tank and add it in time.
Clean the exposed limit switches and bumpers.
Check the air pressure to ensure that the pressure is within the normal range.
Clean the cutting and oil stains on the workbench, machine tool, and three-axis telescopic cover.
Weekly maintenance:
Clean the air filter of the heat exchanger, the cooling pump, and the lubricating oil pump filter.
Check whether the tool pull bolt is loose and whether the tool handle is clean.
Check whether the three-axis mechanical origin is offset.
Check whether the tool magazine tool change arm movement or tool magazine tool disk rotation is smooth.
Monthly maintenance:
Check the lubrication of the X, Y, and Z axis rails to ensure that the rail surfaces are well lubricated.
Check and clean the limit switches and bumpers.
Check whether the oil in the oil cup of the tool cylinder is sufficient, and add oil in time if it is insufficient.
Half-year maintenance:
Disassemble the three-axis chip guard, clean the three-axis oil pipe joints, ball screws, and three-axis limit switches, and check whether they are normal.
Check whether the hard rail scraper of each axis is effective.
Check whether the servo motors and heads of each axis are running normally and whether there are any abnormal sounds.
Replace the oil of the hydraulic unit and the oil of the tool magazine deceleration mechanism.
Annual maintenance:
Check whether all buttons are sensitive and normal.
Clean the cutting water tank and replace the cutting fluid.
Check the vertical accuracy of each axis and decide whether it needs to be adjusted.
2. Parts replacement and troubleshooting
Parts replacement:
Regularly check key parts, such as belts, gears, bearings, etc., and replace damaged or severely worn parts in time.
When replacing parts, choose the appropriate model that matches the original part and install it according to the equipment manual.
Troubleshooting:
Regularly check the connection wires and interfaces of the equipment to ensure that they are firmly connected and not loose or broken.
Check whether the electrical part of the equipment is normal, and repair it in time if there is any abnormality.
Perform regular electrical inspection and maintenance on the equipment to ensure the stable operation of the electrical system of the equipment.
3. Maintenance strategy and technology
Preventive maintenance (PM):
Preventive maintenance is a strategy adopted by most companies, including asset offline, regular inspection, and repair when necessary.
Although the cost of preventive maintenance is relatively high, in the long run, it can effectively reduce the occurrence of equipment failures and extend the service life of equipment.
Predictive maintenance (PdM):
Predictive maintenance is a condition-based asset management method that is usually connected to CMMS through monitoring equipment and generates work orders based on monitoring data.
The advantages of predictive maintenance are that it can save maintenance man-hours, save costs, and provide a deeper understanding of the performance and potential problems of the machine.
Reliability-centered maintenance (RCM):
Reliability-centered maintenance is an in-depth analysis process designed to customize maintenance strategies for each piece of equipment.
This approach can more effectively identify potential failure points of equipment and develop corresponding maintenance plans.
4. Maintenance records and management
Establish a maintenance record system:
Establish a maintenance record for equipment to record the time, content, and responsible person of each maintenance.
Maintenance records are archived for easy access and analysis of equipment operation.
Optimize maintenance resources:
By purposefully sending maintenance information and quickly troubleshooting machine tool equipment failures, users can shorten equipment downtime and accelerate investment recovery.
Optimized spare parts inventory and reduced on-site repair times can further reduce maintenance costs.
Maintenance and maintenance of metal processing equipment are the key to ensuring long-term stable operation and extending the service life of equipment. By formulating reasonable maintenance plans, regular inspections, parts replacement, and troubleshooting, enterprises can significantly improve equipment reliability and production efficiency and reduce operating costs. In the future, with the continuous advancement of technology, intelligent and automated maintenance management systems will provide greater support for enterprises and further improve the efficiency and benefits of equipment management.
