Duplex EcoGrind Machine
High-Precision Double Disc Grinding Machine for Brake Discs
A New Standard in Brake Disc Double Disc Grinding
The Duplex EcoGrind Machine is a double disc surface grinding machine that simultaneously grinds both faces of automotive brake discs. It is Korea's first self-produced model with a PM motor applied. Leading R&D in laser cladding and coated disc grinding, it achieves both energy efficiency and high-precision machining through direct PM motor drive.
Competing with Differentiated Technology
Leading brake disc post-processing with 25 years of accumulated grinding expertise and cutting-edge technology
High Performance
Capable of precisely processing high-hardness, difficult-to-cut materials such as laser-clad and hard metal-coated brake discs — ready for next-generation eco-friendly brake component manufacturing lines.
Reliability
Double bellows covers and AIR PURGE structures are applied to key areas for enhanced durability, ensuring long-term stable operation.
Efficiency
Direct PM motor drive reduces power consumption by 15–50% compared to conventional AC motor grinders. Servo loader automation shortens brake disc grinding cycle times and reduces labor costs.
