These high precision surface grinders have been specially developed and improved in recent years. The optimum span of double V crossfeed guideways is designed based on bending moment, Kinematics and supporting force. All essential castings are made of high grade of cast iron that is stress relieved through annealing to eliminate internal stress. With the greatest stiffness and stability of the castings, these machines are suitable for precision surface grinding. These grinders are offered with one-full-year limited warranty for mechanical and electrical parts.
