Products Description
The CNC knurling stainless steel shaft is made of SUS304, CNC-turned (CNC lathe-machined), and then knurled. Its core feature is the precision knurling process on the shaft surface, creating a uniform, durable, and non-slip texture. The product offers extremely high dimensional accuracy, excellent coaxiality, and superior surface consistency, ensuring reliability and stability during assembly and operation. Whether it's a standard rhombus (diamond) pattern, a straight line pattern, or a custom pattern based on customer drawings, we can achieve it through advanced CNC programming and machining. This product is a key component for precise transmission, adjustment, and gripping functions in modern machinery.
Product-Related Processes
Product technology
The manufacturing of CNC knurling stainless steel shaft combines a number of precision processing technologies to ensure that every link from raw materials to finished products meets the highest standards.
CNC precision turning
First, the stainless steel bar is finely machined using a CNC lathe to ensure that the basic dimensions of the shaft, such as outer diameter, length, and chamfer, reach micron-level tolerances and guarantee excellent surface finish.
Precision Knurling
Knurling, as a mechanical processing technique,
is mainly applied to the handles or mating parts of cylindrical metal components,aiming to create various patterns through rolling.It not only serves an anti-slip function but also has a decorative effect.Its basic forms include straight lines, twill lines and net lines. Each form has its own characteristics and is suitable for different application scenarios.
Deburring and Surface Treatment
After machining, the shaft is thoroughly deburred to eliminate sharp edges and ensure safe handling. Depending on the application, various surface treatment options are available, including mechanical polishing, passivation for enhanced corrosion resistance, and electrochemical polishing for a mirror-like finish.
Manufacturing Process
According to production requirements, select appropriate stainless steel materials and carry out necessary preparations such as straightening, cutting and pre-treatment.
Use equipment such as lathes and milling machines to roughly process stainless steel materials to form approximate shapes and dimensions.
On the basis of rough machining, further processing is carried out on stainless steel materials to make their surface quality and dimensional accuracy meet certain requirements.
According to requirements, stainless steel materials are subjected to heat treatment to enhance their mechanical properties and hardness, etc.
Use knurling tools to perform finishing on stainless steel materials to form the required knurling patterns and dimensional accuracy.
Inspecting on the finished stainless steel knurled shafts to ensure compliance with relevant standards and customer requirements. Finally, appropriate packaging and labeling should be carried out to facilitate transportation and storage.
Understand the material properties of this product - 304 stainless steel
304 stainless steel is a classic chromium-nickel austenitic stainless steel with excellent corrosion resistance, formability, and mechanical strength. Its low carbon content (<0.08%) makes it excellent in generally corrosive environments, making it suitable for most industrial, food, and medical equipment applications. This material also exhibits excellent machinability, ensuring a clear and durable knurled pattern. Furthermore, the inherent high strength, hardness, and wear resistance of stainless steel ensure that the knurled shaft effectively resists wear and maintains its functionality over long-term use.
application
Typical Application Scenarios
CNC knurling stainless steel shaft is widely used in situations where manual adjustment, reliable torque transmission or enhanced friction are required due to its anti-slip, precise and durable characteristics.
