CNC machine tools are usually the key equipment in the mold enterprise. With the upgrading of the technical equipment of modern mold manufacturing enterprises in China, the application of medium and high-grade CNC machine tools is more and more extensive. What follows is how to fully guarantee the effective utilization of the equipment. When the equipment fails, it is necessary to restore the equipment to normal use as soon as possible. Therefore, in the daily workshop management of the mold company, the management and maintenance of CNC machine tools becomes more and more important. CNC equipment management is a very comprehensive comprehensive project, which requires both scientific equipment management and good equipment maintenance.
CNC equipment management and maintenance requirements for personnel
CNC machine tool is a typical mechatronics product that integrates computer technology, automatic control technology, precision measurement technology and modern manufacturing technology. Its control system is complex and expensive, so it puts forward the quality of equipment management and maintenance personnel. The higher requirements of common equipment, these requirements mainly include the following aspects:
1. Have a wide range of electromechanical knowledge
Because CNC machine tools are advanced equipment integrating mechanical, electrical, hydraulic and pneumatic, the quality of personnel directly determines the efficiency and effectiveness of management and maintenance. This requires that the management and maintenance personnel of numerical control equipment should have high quality and require rich professional knowledge, such as mechatronics technology, computer principle, numerical control technology, PLC technology, automatic control technology, drag principle, hydraulic technology, etc. Also master the common knowledge of machining and simple programming of numerical control devices.
2. Good at thinking and learning
The structure of the CNC machine tool is complex, the connection between the various parts is close, and the fault involves a wide range. The management and maintenance personnel of CNC machine tools should be “more motivated and cautiousâ€, not only paying attention to analysis and accumulation, but also being diligent in learning and good at learning. CNC machine tools, especially CNC systems, have more manuals, including operation, programming, connection, installation and commissioning, maintenance manuals, function descriptions, and PLC programming. It is not a day's work to fully grasp these technical materials. According to actual needs, intensive reading of some key chapters related to maintenance, clarifying ideas, grasping key points, and detailing the need to find a needle in a haystack, it is impossible to start, and at the same time, due to more and more The mold enterprises have adopted imported equipment, and the supporting manuals and materials often use the original texts. The alarm text display of the numerical control system is also mostly outside the text. Therefore, it is necessary to have a professional foreign language foundation.
3. Strong hands-on ability
Hands-on is the quality that maintenance personnel must possess. It can be used to operate machine tools and use maintenance tools. The maintenance of CNC machine tools is inseparable from the actual operation. For precision and key equipment such as CNC machine tools, it must have clear purpose, complete ideas and meticulous operating. Especially during the maintenance process. Maintenance personnel usually have to enter special operation modes that cannot be performed by ordinary operators, such as setting and adjusting machine parameters, online debugging through computer and software, and monitoring with PLC programmer. In addition, in order to analyze and judge the cause of the failure, it is often necessary to prepare a corresponding machining program during the maintenance process, and perform necessary running tests on the machine tool and test cutting of the workpiece. Therefore, in a sense, a high-level management and maintenance personnel should operate at a higher level than the operator, and the ability to use programming instructions should be stronger than the programmer.
The main content of CNC equipment management
For mold enterprises, the possession of CNC machine tools is the embodiment of the company's competitive strength. Maximizing the use of CNC equipment is very beneficial to the company to improve efficiency and competitiveness. Mold expert Luo Baihui said that mold companies can not only pay attention to the utilization and optimal functions of numerical control equipment, but also must pay attention to the maintenance and repair of equipment. It is the key to directly affect the long-term normal operation of numerical control equipment. In order to maintain the technical status of several devices and make full use of them, the following aspects should be paid attention to in the basic management and technical management of equipment:
1. Improve equipment management organization
The manufacturing department should set up numerical control equipment and maintenance positions, and undertake the management and maintenance of CNC equipment in the workshop. Employing some experienced professional technicians and mechanical and electrical engineers with strong professional knowledge, responsibility and practical work ability, specializing in the daily management and maintenance of CNC equipment.
2. Formulate and improve rules and regulations
For the characteristics of CNC machine tools, gradually develop corresponding management systems, such as numerical control equipment management system, safety operation procedures of numerical control equipment, operation and use procedures of numerical control equipment, technical management methods of numerical control equipment, maintenance and maintenance procedures of numerical control equipment, etc. Equipment management is more standardized and systematic.
3. Establish a complete equipment file
Establish CNC equipment maintenance files and handover records, record the operation status and fault conditions of CNC equipment in detail, especially record the time, location, cause, solution and resolution process of equipment failure, so as to be recorded in the future. References for reference in the operation and maintenance work.
4. Strengthen the acceptance of CNC equipment
In order to ensure the quality of new equipment, strengthen the installation, commissioning and acceptance of equipment, especially the equipment acceptance, strictly control the indicators related to the important performance and accuracy of the machine tool, and compare the contract, technical agreement, international and domestic standards and the acceptance criteria. The items are checked item by item. After the machine tool is debugged, use the RS232 interface to transfer the machine parameters as a backup to prevent the machine file (parameters) from being lost.
5. Strengthen the maintenance team construction
CNC equipment is a high-tech product that combines machine, electricity, liquid (gas) and light. It has high technical content and is difficult to operate and maintain. Therefore, a high-quality maintenance team must be established to meet the needs of equipment maintenance. The equipment operation technology and maintenance technology training for the operation, maintenance, programming and management of numerical control equipment are carried out in various forms such as equipment installation and commissioning and internal workshops.
