Precision Machined Shaft

The machining characteristics of precision shafts mainly include the following aspects:

High precision machining: The machining accuracy of precision shafts is very high, usually measured in micrometers or even sub micrometers. For example, the diameter accuracy of the journal can reach IT5-IT9, and the accuracy of precision journals can even reach IT5. Geometric accuracy such as roundness and cylindricity also have strict requirements, usually limited to the diameter tolerance range.

Strict process requirements: Precision shaft machining requires the use of highly precise machine tools and equipment, as well as strict process parameters. During the processing, it is necessary to strictly control each link to ensure that the size and surface quality meet the precision requirements. For example, the surface roughness requirement is extremely low, usually within Ra ≤ 0.01 µ m. In addition, processes such as heat treatment and surface hardening also require precise control to ensure the strength and wear resistance of the shaft.

High cost: Due to the need for high-precision equipment and process technology, the cost of precision shaft machining is usually high. This includes higher manpower, material resources investment, and more complex processing procedures.

Wide application areas: Precision shafts are widely used in high-end equipment and products, such as aerospace, defense and military industry, automobile manufacturing, and other fields. These fields have very high requirements for the accuracy and quality of components, therefore precision machining technology is needed.

Comprehensive technical requirements: Precision machining is a multidisciplinary advanced technology that involves processed materials, processing equipment and process equipment, testing methods, working environment, and human skill level. In addition, precision machining is closely related to microfabrication and ultrafine machining, and the development of these technologies has promoted the application of precision machining.

We can make many types of machined parts, either precision or rough, including drive shaft, gear shaft, pin, and connecting bar. 

The materials can be carbon steel, stainless steel, aluminum alloy, etc.

shaft the main parts in the machine,and the tolerance is very critical,looks like a simple parts,

but we always need to spend much time and process on it,

we have the experience to produce the high quality shaft for our customer,
