POREBA TRB 135 CNC LATHES

Technical Description

This CNC lathe features a maximum swing of 53.15 inches (1,350 mm), allowing for the machining of large-diameter workpieces with high precision. The machining length extends up to 708.66 inches (18,000 mm), making it ideal for long shafts and extended components. Powered by a robust 53.63 hp (40 kW) main spindle motor, the machine delivers strong cutting performance suitable for a wide range of materials and demanding turning operations. The spindle achieves a maximum speed of 450 RPM, balancing high torque and efficient material removal rates for optimal productivity. The inclusion of a tailstock enhances workpiece support and rigidity during machining, especially for lengthy or slender parts, ensuring accuracy and surface finish. The machine is equipped with advanced CNC control via the SIEMENS SINUMERIK 840 D sl system, providing precise axis management, flexible programming, and seamless integration with modern manufacturing workflows. This control system supports complex turning cycles, tool management, and high repeatability, making the lathe suitable for both batch production and intricate single-part machining. The combination of generous swing, extended machining length, high power, and reliable CNC control ensures versatility and efficiency in heavy-duty turning applications.
