Japan Standard CNC Machining Processing
When the CNC machine tool replaces the processed parts, it is almost unnecessary to re-adjust the machine tool, which saves the time for installation and adjustment of the parts. The machining quality of CNC machine tools is stable, and generally only the first part inspection and the sampling inspection of key dimensions between the working procedures are used, so the downtime inspection time is saved. When processing on the machining center machine tool, one machine tool realizes the continuous processing of multiple procedures, and the production efficiency is improved more significantly.
(4) Complicated movement can be realized. Ordinary machine tools are difficult or impossible to realize the movement of curves or surfaces with a trajectory of more than three times, such as space surfaces such as propellers and steam turbine blades; while CNC machine tools can realize almost any trajectory motion and process any shape of space surface, which is suitable for For the processing of complex and special-shaped parts.
(5) Good economic benefits. Although the equipment of CNC machine tools is expensive, the equipment depreciation cost allocated to each part during processing is relatively high. However, in the case of single-piece and small-batch production, the use of CNC machine tools can save time for marking, reduce adjustment, processing and inspection time, and save direct production costs. CNC machine tool processing parts generally do not need to make special fixtures, which saves process equipment costs. The CNC machine tool has stable machining accuracy, reduces the scrap rate, and further reduces the production cost. In addition, the CNC machine tool can achieve multiple functions in one machine, saving plant area and plant investment. Therefore, the use of CNC machine tools can obtain good economic benefits.
(6) Conducive to the modernization of production management. CNC machine tools use digital information and standard codes to process and transmit information, especially the use of computer control on CNC machine tools, which lays the foundation for the integration of computer-aided design, manufacturing and management.
At present, as the leading industry of my country's national economy, machinery manufacturing is still the main support for my country's economic growth; as an important support for economic and social development, machinery manufacturing is the main channel for urban employment in my country and a concentrated expression of international competitiveness. However, judging from the current performance, the development of China's machinery manufacturing industry is still far behind that of Western manufacturing powerhouses.
First, total energy consumption is increasing. While the energy intensity has dropped significantly, the total energy consumption of the manufacturing industry in 2015 increased by 2.45 times compared with 2010, and the dependence on foreign oil consumption was close to 50%. While iron and steel, cement, fertilizers and other products are firmly ranked first in the world, a large amount of resources are consumed, and some resources have been seriously constrained by foreign countries; thirdly, the overall technical level is still backward, and core technologies are obviously in short supply; finally, the manufacturing industry continues to grow rapidly At the same time, the welfare benefits of front-line employees have been improved slowly.
