Fully enclosed fiber laser engraving and marking equipment - An efficient solution for metal processing
In the field of metal processing, the surface markings of workpieces cut by traditional saw machines often become blurred or fall off due to oil stains, high temperatures, or mechanical contact. For precision components processed by grinding machines, text marking requires repeated positioning, which is inefficient and has unstable yield rates. To address these industry pain points, fully enclosed fiber laser engraving equipment uses non-contact laser technology to achieve permanent and fine marking on metal surfaces. Its built-in fiber laser and high-speed galvanometer system work together to meet the direct marking needs after multiple processes such as cutting, drilling (used in conjunction with tapping machines), and polishing. It is suitable for efficient marking on stainless steel, aluminum alloys, coated parts, and hard engineering plastics.
This equipment adopts a modular sealed design, effectively isolating processing dust and coolant interference, ensuring the long-term stability of the laser optical path. Its characteristic fundamental mode beam can precisely complete 0.1mm line width engraving, maintaining sharpness in special scenarios such as the quenched surface of automotive bearings and the packaging layer of electronic chips. Compared with traditional air-cooled laser equipment, the compact structure with an integrated air-cooling system saves 30% of production line space. When connected to an automated Grinding Machine, it can even form a flexible processing unit.
Tip
It is recommended to perform laser marking first after the material is cut by the Saw Machine to avoid the offset of the reference surface caused by the subsequent processing of the Tapping Machine. When engraving materials with zinc plating, it is advisable to use a combination of low frequency and high energy parameters to enhance the contrast.
FAQ
Q: Does the device require a water cooling system?
A: This machine is equipped with a patented air cooling structure and can operate continuously without an external cooling device when the ambient temperature is below 40℃.
Q: Is the blackening process supported for titanium alloy?
A: By adjusting the frequency and filling spacing, a permanent black oxidation mark can be achieved on the surface of titanium alloy.
Q: How is the marking depth controlled?
A: The depth is precisely controlled by the coordinated adjustment of three parameters: scanning speed, power, and focal length. The depth control accuracy reaches ±5μm, meeting the depth standards for traceability coding of military components.
Q: What is the after-sales maintenance cycle?
A: The designed lifespan of the laser is over 100,000 hours. Daily maintenance only requires regular cleaning of the optical windows. The annual average maintenance cost is 30% lower than that of similar equipment.
This equipment has now been successfully applied in fields such as automotive parts (for marking bolts in conjunction with Tapping Machines), medical devices (for engraving serial numbers on implants in collaboration with Grinding Machines), and 3C electronics (for marking QR codes on metal casings after cutting with Saw Machines), providing comprehensive solutions ranging from basic identification to precise traceability for metal products.
