Creating a good “working environment” for CNC machine tools and achieving mutual coordination between “people, CNC machine tools and environment” are necessary conditions for users to use CNC machine tools well.
1) CNC machine tools have strict requirements on power supply, and generally require an operating voltage of 22OV±10%;
2) Configuring a suitable automatic programming system for CNC machine tools and quickly and accurately compiling programs is an important part of improving the utilization rate of CNC machine tools;
3) Necessary accessories and tools must be equipped. It should be noted that the unit price of accessories purchased by signing a separate contract is much higher than the unit price of accessories supplied with the main machine. Enterprises with conditions should purchase some vulnerable parts and other accessories together with the main machine as much as possible. In enterprise production, both process and product structure may change;
4) Before processing, the CNC processing processability of parts should be reviewed, and production technology preparation should be emphasized, including CNC processing processability analysis of parts, processing program compilation, tooling and tool configuration, raw material preparation and trial processing, etc., to shorten production preparation time. Reasonably arrange various workpieces suitable for processing on CNC machine tools, and arrange the rhythm of each production link required for CNC machine tool processing and operation.
Strengthening the daily maintenance of CNC machine tools and establishing a “repair center” for CNC machine tools are important guarantees for the long-term and reliable use of CNC machine tools.
1) Pay attention to ensuring the operation rate of CNC machine tools in the early stage of use. Once the CNC machine tool is accepted, it must be put into operation immediately. It will enter the effective operation period (stable construction period) after 9 to 14 months of operation. The CNC machine tool can be put into normal use after a trial period of about 6-12 months. During the warranty period and trial period, the machine tool should be used as much as possible to allow the machine tool to have a sufficient “aging” process.
2) Increase the machine tool’s operating rate so that the hidden dangers of failure can be eliminated as much as possible during the warranty period. Generally speaking, the CNC system should be strengthened with daily maintenance of CNC machine tools. In particular, it should be noted that CNC machine tools should not be sealed and unused for a long time. If you are reluctant to use a CNC machine tool, it will accelerate the deterioration or damage of electronic components due to moisture and other reasons. If the company has no production tasks, the CNC machine tool should be powered on regularly when it is not used for a long time. It is best to power it on 1 to 2 times a week, and run it for about 1 hour each time to prevent the electrical components from getting damp. At the same time, it can also promptly detect whether there is a battery alarm to prevent the loss of system software parameters.
3) Establish a high-level maintenance team. Enterprises with a certain number of CNC machine tools have established a maintenance organization composed of high-level technical personnel to be responsible for CNC machine tool repair tasks. The maintenance organization is directly led by the factory director in charge of the equipment. The members of the CNC machine tool maintenance center should be composed of experienced technicians, electrical engineers, mechanical engineers, maintenance fitters and personnel with strong professional knowledge. Users must use various forms to train them, especially to improve their ability to identify and troubleshoot faults of CNC machine tools.
Strengthening the comprehensive business quality training of CNC machine tool technicians and cultivating a technical team for CNC machine tool applications are the key to users using CNC machine tools well.
To this end, users should pay attention to the following points:
1) Strictly select CNC technicians. CNC machine tools are technology-intensive machine tools, and their operation and maintenance are relatively complex. Therefore, operators, programmers, and maintenance personnel must be carefully selected. In general, the first batch of operators, programmers, and maintenance personnel should select technicians with certain qualifications in related majors as training objects.
2) Strengthen the comprehensive quality training of CNC technicians. The improvement of the comprehensive business quality of CNC technicians depends on technical training and long-term practical training. Users should start to consider the selection and training of personnel when purchasing CNC machine tools. Operators, programmers, and maintenance personnel must undergo professional training before they can take up their posts.
3) Vigorously cultivate a technical team that uses CNC machine tools and take measures to stabilize this team. The utilization rate of CNC machine tools depends not only on the operator’s hands-on ability, but also on the programming skills of programmers and the maintenance skills of maintenance personnel.
