Precision machining: It is realized by using precision machine tools and precision measuring tools/measuring instruments under strictly controlled environment. Machining accuracy up to and above 0.1 microns is called ultra precision machining.
With the development of modern industry and the constant change of demand, precision machining has been developed in many ways. The direction of its development is more and more wide, the direction is also more and more fine, and the direction of its development is more and more showing its specialization. With the development of science and technology, its technology is also constantly improving, the quality and precision of processing. Accuracy is also getting higher and higher. The development of science and technology and economy has also grasped the direction of precision machining development.
In the precision machining process effect:
(1) the accuracy of parts geometry and position is up to micron or sec.
2. The tolerance of parts or dimensions is below microns.
(3) the surface roughness (the average height difference of surface roughness) is less than 0.1 microns.
4. Mutual accessories can meet the requirements of combining ability.
_Some parts can also meet the requirements of accurate mechanical or other physical characteristics, such as the torsional stiffness of the torsion bar of the float gyroscope, the stiffness coefficient of the flexible elements, etc.
With the development of mechanical industry, new design theories and methods, new materials and new technology appear, mechanical parts have entered a new stage of development. Therefore, in the future, precision machining will only be more and more integrated, it is no longer just a simple mechanical processing mode, it is seamless links with high-tech at the moment, but can better play its role, especially in the mechanical processing industry, the digitization of its development has produced a qualitative leap, can be better.
