Advantages of CNC Machining

CNC machining equipment adopts centralized processes, reducing the impact of multiple clamping of workpieces on machining accuracy. The machining accuracy of the product is fully guaranteed by CNC, without the need for manual intervention, which not only reduces the labor intensity of personnel, but also eliminates the impact of human errors on product machining. It is particularly suitable for batch production processes that do not require high operational skills, and demonstrates the advantages of automatic machining.

CNC is superior to traditional machining methods in terms of machining accuracy, quality stability, and operator requirements. However, higher requirements have been put forward for the traditional manual operation mode, production management, process requirements, and working environment of CNC in terms of product capacity improvement, cost control, scientific production management, and humanized requirements. Solving a series of problems in the CNC machining process is not only beneficial for improving production efficiency and capacity, but also for the lean production management of CNC production and machining, enhancing the overall level and image of the enterprise.

The traditional single piece production and processing method results in low efficiency and capital utilization of CNC machining, requiring frequent adjustments during the production process, which consumes a lot of time. The workpieces shuttle back and forth between various processes, which not only has a long cycle but also increases waiting time, resulting in low production capacity, high production costs, and affecting production site management. In order to improve the economic benefits of CNC machining, it is necessary to utilize advanced and efficient production and processing methods, as well as adopt corresponding production organization and management methods.

By utilizing group processing technology, a series of production and management processes from group design, manufacturing to management are completed through the design of group processing technology for similar parts (structures, processes), group production layout, control and balance of group machine load, optimization and sorting of group processing time. Ultimately, the expanded group batch production method was used to improve production efficiency.

The group processing method has been well applied in a customer's product line. Combine three products with similar external dimensions and identical processes for process design and processing. Using a set of fixtures and jigs, complete the processing of the three products after one clamping and positioning. At the same time, the batch processing method of manually clamping multiple sets of grouped products at once (dual station, multi station processing) is adopted to reduce the time required for frequent automatic tool changes in the CNC tool library, thereby shortening the CNC machining CT time, improving the spindle utilization rate, and greatly enhancing the CNC machining efficiency. Reduced the frequency of CNC door opening and closing, reduced human-machine ratio, lowered the demand pressure on operators in production, reduced the frequency of tool changing in the tool magazine, and minimized the impact of oil mist escaping from CNC on the workshop production environment. Finally, through the group multi station processing method, the production efficiency was improved by 30% to 45%, and the number of CNC equipment could be saved by 8% to 10%, and labor could be saved by 45%.
