Customized prototype model is a very important part of the new product design process, so the accuracy of the prototype will directly affect the quality of the product. Generally, products require high precision, and CNC is the preferred processing method. Then, why is CNC processed products with high precision? ?
In terms of machining accuracy, the machining accuracy of ordinary Cnc Machine tools has been increased from 10μm to 5μm, and the precision machining center has increased from 3~5μm to 1~1.5μm, and the ultra-precision machining accuracy has begun to enter the nanometer level (0.01μm) .
cnc machining has the advantages of high precision, high efficiency, high automation, high flexibility, and stable and reliable processing quality. The technical level of CNC machine tools and their percentage of metal cutting machine tool output and total ownership is one of the important indicators to measure a country’s national economic development and the overall level of industrial manufacturing.
CNC lathe is one of the main varieties of CNC machine tools. It occupies a very important position in CNC machine tools. For decades, it has been generally valued by countries all over the world and has been rapidly developed. It has a wide range of processing properties, and can process straight cylinders, oblique cylinders, arcs and various threads. It has various compensation functions of linear interpolation and circular interpolation, and has played a good economic effect in the mass production of complex parts.
CNC machining has the following advantages:
1. The number of tooling can be greatly reduced, and complex tooling is not required for processing parts with complex shapes. If you want to change the shape and size of the part, you only need to modify the part processing program, which is suitable for new product development and modification.
2. The processing quality is stable, the processing accuracy is high, and the repeat accuracy is high, which is suitable for the processing requirements of aircraft.
3. The production efficiency is higher in the case of multi-variety, small batch production, which can reduce the time of production preparation, machine tool adjustment and process inspection, and reduce the cutting time due to the use of the best cutting amount.
4. It can process complex profiles that are difficult to process by conventional methods, and even process some unobservable processing parts. Compared with traditional processing technology, CNC processing is more convenient and practical.
