CNC machining accuracy can be up to how much

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

CNC machining with high precision, high efficiency, high automation and high flexibility, stable and reliable processing quality and other advantages of the workhorses. CNC machine tool technology level and its high and low in metal cutting processing machine tool production and the percentage of total ownership is a measure of a country's national economic development and the overall level of industrial manufacturing is one of the important symbols.

CNC lathe is one of the main varieties of CNC machine tools, which occupies a very important position in the CNC machine tools, over the past few decades has been universally recognized by the countries of the world and has been the rapid development. It has a wide range of plus process performance, can be processed linear cylindrical, oblique cylindrical, circular arc and a variety of threads. With straight line interpolation, arc interpolation various compensation functions, and in the mass production of complex parts to play a good economic results.

Expanded information:

CNC machining has the following advantages:

1, Massive reduction in the number of fixtures, processing complex shape of the parts do not need complex fixtures. If you want to change the shape and size of the parts, you only need to modify the parts machining program, suitable for new product development and retrofitting.

2, stable processing quality, high processing accuracy, high repeatability, adapt to the processing requirements of the aircraft.

3, multi-species, small batch production in the case of higher production efficiency, can reduce the production preparation, machine tool adjustment and process inspection time, and due to the use of the optimal amount of cutting and reduce the cutting time.

4, can be processed by conventional methods difficult to process complex surfaces, and can even process some unobservable processing parts.
