What is the precision of CNC machining

Many customers have some doubts about the effect of CNC machining. This article will introduce the machining accuracy of CNC to you.

In terms of machining accuracy, the machining accuracy of ordinary CNC machine tools has been increased from 10 μm to 5 μm, and the precision machining center has increased from 3 to 5 μm to 1 to 1.5 μm, and the ultra-precision machining accuracy has begun to enter the nano level (0.01 μm). 

CNC machining has the advantages of high precision, high efficiency, high automation and high flexibility, and stable and reliable processing quality. The technical level of CNC machine tools and their percentages in the output and total ownership of metal cutting machine tools are one of the important indicators to measure the development of a country's national economy 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. It has been widely valued by countries all over the world for decades and has developed rapidly. It has a wide range of processing capabilities, 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 is 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 precision is high, and the repeatability is high, which is suitable for the processing requirements of aircraft.

3. The production efficiency is high in the case of multi-variety and small batch production, which can reduce the time for production preparation, machine tool adjustment and process inspection, and the cutting time is reduced due to the use of the optimal cutting amount.

4. It can process complex profiles that are difficult to process by conventional methods, and even process some unobservable processing parts.
