Technical Specifications

Key Features

• High-Voltage Penetration Power: This electrolytic polishing rectifier generates up to 350V to overcome high electrical resistance. Therefore, it is uniquely capable of processing parts with complex internal channels, long pipes, or when using specialized low-conductivity electrolytes, where standard low-voltage systems fail.
• Precision Control for Critical Finishes: With programmable VI (Voltage-Current) curves and pulse capabilities, it allows meticulous control over the polishing profile. As a result, users can achieve precise surface leveling on critical aerospace or medical components without over-etching or burning delicate features.
• Robust & Intelligent System Design: Built for industrial 24/7 operation, it features arc detection and insulation monitoring to protect both the workpiece and the rectifier during high-voltage processes. Moreover, automatic compensation for changing bath conditions maintains consistent results throughout long production runs.
• Versatility Beyond Standard Polishing: The wide output range makes it suitable for high-voltage anodizing, electrophoretic processes, and other specialized electrochemical treatments. Furthermore, this multifunctionality provides exceptional value for R&D centers and job shops handling diverse, high-value projects.

Applications & Advantages

This high-power rectifier solves unique challenges in advanced manufacturing and surface engineering.

In Aerospace & Defense, it polishes and deburrs internal channels in titanium and nickel-alloy turbine blades, fuel system components, and complex manifolds. Importantly, the high voltage ensures current reaches all interior surfaces, which is vital for part performance and fatigue resistance.

For Medical Implant Manufacturing, it processes porous titanium structures and complex spinal implants, creating a biocompatible surface finish deep within the matrix. Additionally, the precise control prevents hydrogen embrittlement and preserves the structural integrity of vital implants.

In Semiconductor & High-Purity Manufacturing, it polishes the interiors of high-alloy stainless steel gas delivery systems and chamber components. Ultimately, this achieves the ultra-clean, particulate-free surfaces required to prevent contamination in sensitive fabrication processes.

Finally, this 200A 350V rectifier is a cornerstone technology for pushing the boundaries of electrochemical finishing. For this reason, it is the definitive power solution for industry leaders who must process the most challenging geometries and materials to the highest possible standards.
