我国研制微型精密轴开始的，随着电子产品、办公用品自动化的，不断发展，微型精密轴类加工的应用优先域不断扩大，尤其是微电机工业的发展促进了微电机轴在国内的研制和生产。

 

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.

 

 

 

随着九十年代录像机在我国生产的发展，特别是与中国的合资公司的建成和投产，又推动了录像机用精密微型轴的发展，近几年，由于电子计算机、通讯和办公现代化的发展应用在这一方面的精密微型轴的种类越来越多由原来的三五种发展到目前的几百种，形式也由原来的以直杆光轴为主，发展到现在的车槽、铣扁、滚花、钻孔和滚齿等多种形式。

 

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.

 

 

 

 

一般情况下，精密微型轴类加工的直径范围大致：是从12毫米到6毫米，长度从10毫米到60毫米，但随着产品的不断小型化，高性能化，精密微型轴的尺寸和精度也较十年前发生了很大变化，直径和长度范围都扩大了，分别是0.6毫米到8毫米和4毫米到W毫米。直径公差由原来的6微米变成现在的1微米，圆度要求0.5微米以下，直度要求0.5微米以下，表面粗糙度要求RmaXO．3S以下。

 

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.

 

 

 

微型精密轴应用的优先域非常广泛，而全世精密轴产量的一半以上在亚洲，中国又占据 其中1／4的产量，因此，国内精密轴的生产有作为。

 

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.
