Structural Steel Frame Automatic Electropolishing Equipment With Anti Corrosion Coating

Automatic Elaectropolishing Machine

This electropolishing equipment is designed for industrial metal surface finishing, particularly for large or structural metal components that require improved surface smoothness, cleanliness and corrosion resistance. The system uses an electrochemical polishing process to selectively remove microscopic surface irregularities from conductive metal workpieces.

Electrolytic Polishing

Electrolytic polishing is a surface-finishing process in which metal workpieces are connected as anodes and selectively dissolved in an electrolyte to remove surface roughness and improve smoothness.

It can enhance corrosion resistance, reduce electrical contact resistance, improve surface reflectivity and dimensional accuracy, and provide a clean decorative finish. The process is suitable for stainless steel, aluminum, copper, nickel, and various alloys.

Equipment Features

• Main Frame: A3 structural steel with epoxy anti-corrosion coating.
• Transport System: Horizontal and vertical jig movement driven by geared brake motors for stable operation and easy maintenance.
• Positioning: Induction-based deceleration and positioning for accurate workpiece transfer.
• Lifting System: Acid-resistant, aging-resistant belt with geared motor and coupling.
• Speed Control: PLC and frequency converter with low, medium, and high speed settings to minimize vibration and improve positioning accuracy.
• Safety: Emergency stop devices are integrated throughout the line.

Control System

The line uses Mitsubishi PLC and inverters, a Kunlun Tongtai touchscreen, and Omron sensors and control components. Automatic and manual modes are available for process timing, transfer speed, lifting speed, and workpiece positioning. The control system also supports power-failure memory and interruption recovery.

Specifications

Quality Control

Each electropolishing system is inspected before shipment to verify equipment structure, electrical connections, control functions and key process components.

Quality checks may include:

• Tank and structural assembly inspection
• Electrical wiring and control cabinet inspection
• Rectifier output verification
• Pump and circulation system inspection
• Transfer or lifting mechanism testing
• PLC/control function testing
• Trial operation before shipment
• Final inspection against approved specifications

For customized projects, inspection items can be agreed with the customer according to the equipment configuration and production requirements.
