Automatic Tank Polishing Machine

---

I. Product Overview

The Double-Head Automatic Tank Polishing Machine is a high-end CNC equipment specifically developed for the intelligent finishing of medium to large-scale tanks. With a processing range of φ500–5000mm (expandable to 6000mm), it features a collaborative dual-head system, a dual-axis intelligent frequency drive platform, and a heavy-duty roller structure to achieve fully automated, high-consistency, and continuous polishing.

Standard Configuration:

• 5.5kW High-Torque Spindle System

• Dual-Inverter Synchronous Drive System

• Intelligent PLC Control + HMI (Human-Machine Interface)

• Heavy-Duty Load-Bearing Roller Station

• Modular Quick-Change Abrasive System

Applications: Widely used in chemical equipment, food engineering, shipbuilding, energy, and LNG sectors for automatic weld grinding, uniform mirror polishing, and continuous finishing of internal and external walls.

Core Philosophy: "Minimize manual intervention, Maximize processing consistency."
