Wet Metal Polishing Machine: A Dual Breakthrough in Environmental Protection and Efficiency, the Secret Weapon for Premium Metal Surface Finishes

Metal processing enterprises are facing dual pressures: on one hand, market requirements for product surface finish are increasingly stringent—products such as automotive shells, medical devices, and high-end hardware need a smooth texture with surface roughness controlled below Ra0.4μm; on the other hand, environmental supervision is intensifying. Metal dust generated by traditional dry polishing not only poses explosion risks but also leads to penalties for enterprises due to excessive dust emissions. According to the 2025 Industrial Dust Removal Equipment Industry White Paper, 21.5% of metal processing enterprises were forced to suspend production for rectification due to non-compliance with environmental standards. The advent of the wet metal polishing machine perfectly resolves the conflict between "precision demand" and "environmental pressure", becoming the preferred solution for metal surface treatment.
Centered on "water-based environmental media + precision polishing technology", this equipment impacts workpiece surfaces with abrasives carried by water flow, removing burrs and oxide layers while completing polishing. No dust is emitted throughout the process, workshop air quality meets national environmental standards, and dust explosion risks are eliminated at the source. Compared to dry polishing, wet processing effectively lowers workpiece temperature, avoiding material deformation and surface burns caused by high temperatures—especially suitable for heat-sensitive materials such as aluminum-magnesium alloy and titanium alloy. A 3C electronics enterprise in Shenzhen previously used dry polishing for mobile phone frames, facing frequent environmental interviews due to dust pollution and frequent scratches and color differences on finished products. After switching to the wet metal polishing machine, it not only completely solved the dust problem but also reduced product surface roughness from Ra1.6μm to Ra0.3μm, with the defect rate dropping from 8% to below 0.1%, successfully securing supply orders from Huawei and Xiaomi.
The intelligent servo system of the equipment is a major highlight, capable of real-time monitoring of workpiece positions during processing and automatic adjustment of water flow to ensure processing quality remains within the ideal range. In addition, the machine is equipped with a servo positioning automatic compensation system, which automatically adjusts product positions according to processing progress to guarantee the consistency and stability of polishing effects. When processing new energy vehicle battery shells, the equipment ensures surface finish while effectively eliminating oxidation marks from welding, greatly enhancing product appearance quality and market competitiveness.
The wet metal polishing machine achieves a "dual upgrade in quality and efficiency" in polishing efficiency and effect. Adopting a modular design integrating rough polishing, fine polishing, and cleaning, it completes the entire process with one clamping, boosting efficiency by 300% compared to traditional step-by-step processing. Its intelligent control system adapts to different workpiece materials and requirements, delivering uniform polishing for ordinary metals such as carbon steel and stainless steel, as well as difficult-to-process materials like titanium alloy and high-temperature alloy. It removes oxide layers, rust, and oil stains while forming a smooth and delicate surface texture, improving adhesion by 50% compared to traditional processes and providing a perfect base for subsequent painting and electroplating.
Diversified customized solutions are available for different application scenarios: small models adapt to small-batch precision parts such as hardware accessories, and large units meet mass production needs for new energy vehicle battery trays and aerospace structural parts; explosion-proof designs adapt to harsh environments with dust concentrations up to 500g/m³, and vacuum adsorption models solve deformation problems in ultra-thin sheet processing. In terms of cost, the equipment uses a circulating water supply system with over 95% water resource utilization, reducing abrasive loss by 60% compared to dry polishing and cutting comprehensive long-term use costs by 40%. Currently, wet polishing has become a mainstream trend in high-end metal processing, with increasing penetration in automotive manufacturing, medical devices, high-end decoration, and other industries.
