Overview of Types and Precision Development of Micro Precision Shaft Machining
developed in our countryMiniature precision shaftAt the beginning, with the continuous development of electronic products and office supplies automation, the application field of micro precision shaft processing is expanding. In particular, the development of the micro-motor industry has promoted the development and production of micro-motor shafts in China.
With the development of the production of video recorders in China in the 1990 s, especially the completion and commissioning of joint ventures with China, the development of precision miniature shafts for video recorders has been promoted. In recent years, due to the development of electronic computers, communications and office modernization, more and more types of precision miniature shafts have been applied in this area from the original three or five to the current hundreds of types, and the form has also changed from the original straight shaft. Development to the current car groove, milling flat, knurling, drilling and hobbing and other forms.
Under normal circumstances, the diameter range of precision micro-shaft processing is roughly: from 12mm to 6mm, and the length is from 10mm to 60mm. However, with the continuous miniaturization and high performance of products, the size and precision of precision micro-shafts have also changed greatly compared with ten years ago, with the diameter and length ranges expanded to 0.6mm to 8mm and 4mm to W mm respectively, the diameter tolerance has changed from the original 6 microns to the current 1 micron, the roundness is required to be below 0.5 microns, the straightness is required to be below 0.5 microns, and the surface roughness is required to be below RmaXO.3S.
Miniature precision shaftThe field of application is very wide, and more than half of the world's precision shaft production is in Asia. China accounts for 1/4 of the output, so the production of domestic precision shafts is promising.
