Recently, a customer team specializing in automotive precision bearing parts visited Chongqing Chuke Intelligent Machinery Equipment Co., Ltd. (hereinafter referred to as "Chuke Intelligent") to conduct on-site laser marking sample testing of components. Technical engineers accompanied the operation and debugging throughout the process, and the finished product with 360° circular serial number engraving received full recognition from the customer.
The visiting company mainly deals in precision bearing components for automotive transmission and chassis, and its products have stringent requirements for metal marking processes. Traditional processes such as inkjet printing, chemical etching, and steel stamping present multiple production challenges: inkjet printing is prone to flaking off when exposed to oil, making full-process traceability of parts difficult; etching causes significant pollution and can damage the precision plating of bearings; steel stamping has low processing efficiency, producing inconsistent character depth and making it unsuitable for automated production line quality inspection. With increasingly stringent product traceability regulations in the automotive parts industry, the customer specifically came to the site to verify the machine and find a high-precision laser marking solution suitable for curved pipe fittings.
To address the customer's requirement for marking the outer edge of bearing pipe fittings, the team selected and tested the Chuke Intelligent self-developed fiber laser marking machine on-site. This marking machine produces a fine and uniform laser spot, capable of printing a complete circle of continuous serial numbers on the outer wall of cylindrical pipe fittings, with clear, burr-free character edges. The processing force is gentle and does not damage the original substrate plating of the bearing. The machine is compatible with various commonly used metal materials in automotive parts, such as stainless steel, alloy steel, and chrome-plated parts. The engraved markings are abrasion-resistant, high-temperature resistant, and resistant to acid and alkali corrosion. The markings will not become blurred even after long-term use of the parts, achieving full life-cycle traceability of the product.
Engineers matched a specialized rotating fixture to the outer diameter of the pipe fitting, achieving 360° uniform speed positioning and rotation of the workpiece. The control system imported the customer's customized traceability code template, generating a circular marking path with a single click. During the hands-on demonstration, visiting customers observed the entire process, meticulously reviewing software parameter adjustments, workpiece fixation, and the complete laser engraving procedure. Engineers held a finished bearing pipe fitting on-site, comparing the engraving quality at different power levels and processing speeds, and simultaneously answering customer questions regarding production line integration, 24/7 uninterrupted mass production, and subsequent equipment maintenance costs. The entire process is simple and convenient to operate; processing a single pipe fitting's circular serial number takes only seconds, far exceeding the production efficiency of traditional methods. The entire process requires no ink and generates no chemical waste, meeting the factory's green production standards.
Chuke Intelligent has nearly 20 years of technological expertise in the research and development and production of laser precision processing equipment. Focusing on the entire process of marking, cleaning, and engraving automotive and motorcycle parts, they can provide customized services for single-machine equipment and automated systems based on workpiece specifications and factory production line conditions. Going forward, Chuke Intelligent will continue to optimize its core processes for curved surface marking and high-speed online labeling, providing stable, efficient, and environmentally friendly intelligent processing equipment for a wide range of auto parts manufacturers, and promoting the digital traceability and intelligent manufacturing upgrade of the auto parts industry.
