Description

The Robins SG12 Smart is a heavy-duty seat and guide machine built to handle everything from small motorcycle heads to large multi-valve diesel heads in one setup. Its full-rotation roll fixture gives complete access for seat cutting, drilling, tapping, injector tube work, and thread repair.

The Smart model adds the Robins Touchscreen Interface, allowing fast control of spindle speed, feed, and depth while switching instantly between manual and Smart-screen operation. The built-in Dual Centering System and Robins Guide Honing Kit ensure precise guide geometry and near-zero runout for consistent seat quality across all engine types.
