FAQ

Is the CG3 compatible with industry-standard tooling?

Absolutely. Engineered on a globally recognized platform, all core wear parts are 100% interchangeable with standard 450mm models. The universal tool holder seamlessly supports Redi-Lock systems, allowing fleet owners to utilize existing stock with zero risk

Why choose variable speed over fixed speed grind？

Versatility and control. Fixed-speed models handle basic grinding, but the Yaskawa VFD edition expands the operating window. Adjust RPM precisely to run a heavy-duty concrete grinder for epoxy removal at low speeds, or high-gloss resin polishing at high speeds without motor stalling

How reliable is the electrical system for heavy-duty job sites?

Built for elite uptime. Premium Schneider Electric switchgear and Yaskawa VFDs protect the internal architecture against unstable job site voltage—minimizing downtime and reducing maintenance for any planetary concrete grinder for rental fleet operations
