Do you know the types of precision shafts and the overview of processing development?

Since the development of micro-precision shafts in my country, with the continuous development of electronic products and office supplies automation, the application fields of micro-precision shaft processing have continued to expand, especially the development of the micro-motor industry has promoted the development and production of micro-motor shafts in China. .



With the development of automation of electronic products and office supplies, the application field of micro-precision shaft processing has been expanding. The development of micro-motor industry in particular has promoted the development and production of micro-motor shaft in China .







With the development of video recorder production in my country in the 1990s, especially the establishment and commissioning of a joint venture with China, it has also promoted the development of precision micro-shafts for video recorders. In recent years, due to the modernization of electronic computers, communications and office The types of precision miniature axles used in this area are increasing from the original three or five kinds to the current hundreds of kinds, and the form has also been developed from the original straight rod optical shaft to the current car slot. , Milling, knurling, drilling and gear hobbing.



With the development of production of video recorders in China in the 1990s, especially the establishment and commissioning of joint ventures with China, the development of precision micro-axes for video recorders has been promoted. In recent years, more and more types of precision micro-axes have been used in this field due to the development of computer, communication and office modernization. Three or five kinds have developed to hundreds of kinds at present, and their forms have also changed from straight rod optical axis to slot, milling flat, knurling, drilling and hobbing.









In general, the diameter range of precision micro shaft machining is roughly: from 12 mm to 6 mm, and the length is from 10 mm to 60 mm. However, with the continuous miniaturization and high performance of products, the precision of micro shafts The size and accuracy have also changed a lot from ten years ago, and the diameter and length range have been expanded to 0.6 mm to 8 mm and 4 mm to W mm, respectively. The diameter tolerance has changed from the original 6 microns to the current 1 micron. The roundness requires less than 0.5 microns, the straightness requires less than 0.5 microns, and the surface roughness requires RmaXO. Below 3S.



Generally speaking, the diameter range of precision micro-axis 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-axis have changed a lot compared with ten years ago, and the diameter and length range have expanded to 0.6mm, respectively. Meters to 8mm and 4mm to Wmm. Diameter tolerance is changed from 6 microns to 1 micron, roundness is less than 0.5 microns, straightness is less than 0.5 microns, and surface roughness is less than RmaXO. 3S.







The application field of miniature precision shafts is very wide, and more than half of the world's precision shaft production is in Asia, and China accounts for 1/4 of the production. Therefore, domestic precision shaft production is promising.



Miniature precision shafts are widely used in many fields, and more than half of the world's precision shafts are produced in Asia, and China accounts for 1/4 of them. Therefore, the production of domestic precision shafts has made a great contribution .
