High-precision five-axis CNC lathe knurled copper machining and customization production

Ganyuan Factory has focused on knurled copper parts machining for over twenty years. Relying on high-precision CNC machine tools, we precisely control the knurling depth, texture uniformity, and overall dimensions, ensuring that parts possess both clear anti-slip textures and excellent electrical and thermal conductivity.

Product description

CNC Machining Enhances the Performance and Aesthetics of Knurled Copper Parts

In the fields of precision hardware and high-end instrument components manufacturing, knurled copper parts, with their unique texture, excellent electrical and thermal conductivity, and elegant appearance, have become a key carrier connecting function and aesthetics. Faced with the special processing characteristics of copper and the high precision requirements of the knurling process, traditional processing methods often struggle to simultaneously achieve texture consistency, dimensional accuracy, and surface integrity. Based on over twenty years of CNC precision machining experience and innovative process accumulation, we have successfully applied digital machining technology to the manufacturing of knurled copper parts, achieving a triple breakthrough in function, precision, and aesthetics.

I. Consistent Reproduction of Precision Knurling Textures

The core value of the knurling process lies in providing a stable and reliable visual texture. We employ ultra-high precision CNC lathes and a customized knurling tool system, digitally controlling the depth, angle, and spacing of each texture to ensure that complex textures such as straight knurling and cross knurling are evenly distributed on the surface of the part.

II. Composite Process Integration: Multiple Processing Steps in a Single Clamping

Copper knurled parts often need to integrate multiple functional features such as precision threads, stepped surfaces, and irregularly shaped holes. Through multi-axis CNC machining centers, we can sequentially complete turning, milling, drilling, and knurling processes in a single setup, ensuring a relative positional accuracy of ±0.005mm between features. This integrated machining strategy not only effectively avoids the cumulative errors caused by multiple setups but also improves machining efficiency by over 40%, making it particularly suitable for high-precision applications such as optical equipment.

III. Surface Integrity Control: From Microstructure to Macrotactile Feel

Copper is prone to burrs and material adhesion during machining, affecting the clarity of the knurling texture and tactile comfort. By optimizing tool geometry, employing micro-lubrication and cooling technology, and precisely controlling cutting speed and feed rate, we achieve a burr-free and adhesion-free ideal surface while completing precision knurling. Combined with post-processing techniques such as vibration finishing and electropolishing, the knurled surface achieves an ultra-fine Ra of less than 0.2μm.

In the high-end manufacturing field, where quality and precision are equally important, knurled copper parts are evolving from simple functional components into important carriers integrating ergonomics and visual aesthetics. Through continuous innovation in CNC machining technology, we have not only achieved a leap in precision of traditional knurling processes, but also built new bridges between materials science, surface engineering, and user experience.
