The only grinder exclusively designed for machining sleeves and rollers coated in rubber and/or technopolymers. The double function of initial roughing (removal using a specific surface layer tool) and final precision grinding make the product excellent for every type of work, allowing all the machining phases by positioning the piece just once. Maximum precision and high performance guarantee perfection in all machining processes: trapezoidal-conical profile, de-layering, edge trimming, turning and grinding. The compact size of the machine, the elimination of intermediate warehouses (no longer necessary because the piece is finished directly on the machine),the reduced maintenance and the fast ROI are just some of the advantages offered by this innovative product.

• Solid structure in painted steel • Linear precision guides with a reduced range for working head sliding • Two independent working heads for roughing and grinding • Quality mechanical and electronic parts • Measurements digital display • Tools developed to guarantee high production yield
