A Special Note on the GC12 Series
All GC12 series machines have a 10° slant table which is easy to clean and guide the coolant fluid back to the machine reservoir. The 10° slant provides the gravity force to keep the workhead and tailstock stand on the table and against the grinding normal force, enhancing the rigidity and efficiency of grinding. The Z-axis positioning accuracy and repeatability is assured with an AC servo motor and a high precision ball screws. The lubrication design is similar to the wheel head guideways the multi-point flow adjustable lubrication system together with the high accuracy hand scraped ways ensures the table travel movement without any stick-slide on full table speed range even when the speed is low to 4 inches per minute. The table also has a built-in swivel system with a stand for the dial indicator for the tapered adjustment of the parts.

Turn-key/automation for high production applications, Ecotech offers solutions with several automation possibilities, fitting the customer´s requirements. The loading system varies depending on the part´s specifications.
GC12 - This is our best production cylindrical grinder. The design is based on our most popular manual cylindrical grinder GM12. Achievable roundness 0.0001"(0.0025mm) for standard test part ground between center.
