In the field of metal processing, metal CNC parts precision machining not only improves production efficiency but also significantly enhances product quality. The advantages of CNC machining technology allow it to perform exceptionally in various application scenarios. This article will detail the processing characteristics of metal CNC parts and the CNC process design for complex parts to help you better understand and apply this technology.
The main characteristics of metal CNC parts processing include efficiency, precision, and automation. These characteristics make CNC machining one of the indispensable technologies in modern manufacturing.
Metal CNC parts processing can handle multiple surfaces simultaneously, saving production time compared to traditional lathe processing methods. CNC technology can reduce processing steps and manual intervention, improving processing efficiency. Additionally, the stability of CNC machining is superior to ordinary lathe processing, ensuring better quality of parts.
In the development of new products, metal CNC parts processing's flexibility is particularly prominent. Through programming, various complex part shapes can be easily handled. Modifications and updates to product designs only require program adjustments, eliminating the need to redesign tools or equipment, thereby greatly shortening the product development cycle.
Metal CNC parts processing is highly automated, significantly reducing the physical labor intensity of workers. During operation, workers do not need to control the equipment throughout the entire process as in traditional lathe operations; they only need to supervise and adjust the equipment. Nevertheless, CNC machining requires a high level of technical proficiency and operating skills to ensure the equipment runs smoothly.
Although metal CNC parts processing requires a high initial investment due to the high cost of CNC lathes and maintenance, its long-term efficient production and stable quality usually bring higher returns. Investing in CNC machining equipment not only increases production efficiency but also enhances market competitiveness.
For complex metal CNC parts, process design and analysis are crucial steps in ensuring successful machining. Below are the key points for the analysis and design of CNC machining processes for complex parts.
When designing the processing technology of metal CNC parts, the first step is to determine the appropriate raw material. The selection of raw material includes determining the type, manufacturing method, and allowance. For steel parts, treated steel is usually chosen to ensure it is suitable for cutting. The raw material selection should consider the structure and shape dimensions of the part to ensure that the main processing steps can be completed in one go.
The reference for positioning of metal CNC parts is a key factor in determining processing precision. The choice of rough reference should ensure that the dimensions and position between the processed surface and the unprocessed surface meet the drawing requirements. For the processing of grooves or holes, the plane or bottom surface of the raw material is usually selected as the rough reference to ensure machining accuracy.
When formulating the process route, various stages and sequences of processing must be considered. The process route for metal CNC parts should include selecting appropriate processing methods, dividing processing stages, and determining the feed processing route. Whether this step is done correctly directly impacts the quality and efficiency of the part.
Different types of metal CNC parts should be processed on corresponding CNC machine tools. Based on the design requirements of the parts, the appropriate machine tools are selected:
CNC lathes are suitable for processing complex-shaped shaft parts and rotary molds.
CNC vertical boring and milling machines and vertical machining centers are suitable for processing boxes, templates, and complex flat or three-dimensional parts.
CNC horizontal boring and milling machines and horizontal machining centers are suitable for processing complex boxes, pump bodies, valve bodies, etc.
