RAFAMET KKB 150 N VERTICAL BORING MILL

The RAFAMET KKB 150 N Vertical Boring Mill is a single-column Vertical Turning and Boring Mill, also classified as a Vertical Wheel Lathe, engineered primarily for the productive machining of railway wheels. This machine is characterized by its robust and rigid construction, featuring a monolithic structure where the machine column and cross-rail are combined into a single piece. Major body components are high-grade grey iron castings, heavily ribbed and box-type, designed to provide maximum vibration damping during the cutting process. Key technical specifications include a Table Diameter of 57.09 inches (1450 mm), a Swing/Maximum turning diameter of 78.74 inches (2000 mm), and a Main Drive Power of 487.36 horsepower (362.5 kW), offering continuously variable speed control via a modular torque motor, with a maximum speed of 400 RPM. Operation is managed by a CNC control system. The machine is equipped with a solid forged steel railhead ram, which includes a Coromant CAPTO quick-change tool adapter for efficient tooling changes and potential extension of capabilities to operations such as machining solid wheels, wheel centers, and boring tyres.
