Double head tank polishing machine

1. Product Overview

The Double-Head Tank Polishing Machine is designed for the efficient surface finishing of large-diameter tanks, with a processing range of φ500–5000mm (optional extension to 6000mm). It integrates a high-torque 5.5kW polishing head, dual-axis frequency-controlled system, and a heavy-duty rotary tank roller. Suitable for chemical containers, food-grade tanks, LNG vessels, and shipbuilding equipment, the system supports rapid tool switching and delivers mirror-grade finishes with Ra ≤ 0.4μm. Its modular design ensures low power consumption, reduced maintenance, and adaptability to various production environments.

2. Key Product Features

• Exceptional Processing Range
  Handles workpieces from φ500mm to φ5000mm, one of the widest ranges in the industry. Optional beam extension supports tanks up to 6 meters long.

• High-Torque Polishing Head
  5.5kW 2-pole motor with 35N·m torque output. Maintains smooth operation even at 500rpm low-speed setting for steady grinding.

• Smart Control Architecture
  Dual inverter synchronization with <0.5% speed deviation, intelligent overload protection (<0.1s response), and a user-friendly HMI interface.

• Energy-Efficient Modular Design
  Operates at just 8kW total power—40% lower than industry average. Modular structure reduces maintenance time by 50%.

• Flexible Model Options
  Available in Basic, Advanced, and Custom configurations, supporting automation, dust extraction, robotic integration, and ultra-heavy load upgrades.
