The Robins Rubi Surf 1.7 is a precision resurfacing machine built for cylinder heads and engine blocks from automotive, diesel, and industrial engines. Its rigid cast-iron construction and ball-screw table feed ensure stability and perfectly flat sealing surfaces on both aluminum and cast iron.
Powered by Robins’ proprietary SMART operator software, designed for the RubiSurf Series, the RS 1.7 delivers 30% to 50% higher productivity with superior surface finish and flatness. All traditional switches are eliminated, with key functions digitally integrated, including:
The inverter-driven spindle motor supports CBN, PCD, and carbide tooling for MLS-quality finishes. With CNC-style automation, faster setup, and consistent precision, the Robins RS 1.7 provides engine rebuilders a high-performance alternative to traditional resurfacing machines in this class.
