How to do CNC processing with high efficiency
1. Implement scientific management in CNC processing
CNC machine tools are very different from ordinary machine tools, so the management method of ordinary machine tools cannot be applied to CNC machine tools. Through years of practice, the management method of CNC machine tools using "professional management and centralized use" is more effective. The preparation of process technology can be carried out by the process technology department of the factory, and the production tasks can be assigned uniformly. For some enterprises with good conditions, computer integrated management system can be used for production mode management. The effective information is counted and planned, and the purpose of improving production is achieved by reducing production preparation time and optimizing logistics routes.
2. Reasonable selection of cutting tools
Cutting tool is an important link in machining, especially in ensuring machining quality and improving machining efficiency. With the development of CNC machine tools towards high speed, high rigidity and high power, the requirements for cutting tools are also raised. In order to meet the development trend of CNC machine tools, tools are also developing towards high-performance stability. Therefore, when selecting tool materials, it is generally necessary to select cemented carbide tools according to the processing conditions. If conditions permit, you can also choose to use coated tools with better wear resistance and more stable performance, cubic nitriding tools, ceramic tools and so on.
3. Application of tool clamping
The choice of tool clamping mode directly affects the installation time and measurement time of the workpiece, and also has a certain impact on the errors in product processing. Therefore, the following aspects should be paid attention to in the selection and application of workpiece clamping methods:
(1) Popularizing and improving the assembly of combined fixture and vacuum fixture can effectively shorten the auxiliary time.
(2) Improve the unity of positioning standards, reduce the workload in the positioning process and the number of fixtures.
(3) Using the force fixing fixture can effectively deform the workpiece, which is of great help to improve the machining accuracy.
(4) For tooling fixtures, computer-aided management system can also be used.
4. The preparation of processing program should be reasonable
The use level of CNC machine tools has raised the technical requirements for equipment operators. It is necessary to understand not only the technical content, but also the programming skills and machining process level. A good program should have the minimum program segments and the shortest processing cycle of the workpiece on the premise of ensuring the processing quality. This is a challenge for equipment operators.
5. Machine tool maintenance
Because the cost of CNC machine tools is very high, machine tool maintenance is of great help to improve the service life of equipment and reduce costs to a certain extent. The maintenance protection of machine tools mainly includes three aspects:
(1) Preventive maintenance: this kind of maintenance can ensure the normal operation of the machine tool.
(2) Fault maintenance: troubleshooting and clearing when the machine tool breaks down.
(3) Restore the normal operation of the equipment: transform the old CNC machine tools to improve the efficiency of the equipment.
6. Innovative process methods
With the progress of science and technology, technological methods are also developing. In current general companies, process methods can not effectively improve the processing efficiency of CNC machine tools, so enterprises should strengthen innovation training, innovate in process technology, and improve the processing efficiency of CNC machine tools.
