STAR SB-20R CNC LATHE

Technical Description

This CNC lathe is engineered for high-precision turning operations with dual spindles, supporting efficient and versatile machining of small to medium-sized parts. The main spindle delivers a maximum cutting/turning diameter of 0.79 inches and features a matching spindle bore, enabling the processing of bar stock up to this size. It operates at speeds up to 10,000 RPM, powered by a robust 5 HP motor, ensuring rapid material removal and fine surface finishes. The second spindle, with a bore of 0.79 inches and a maximum speed of 9,000 RPM, is driven by a 1.5 HP motor, allowing for secondary operations such as backworking or part transfer without manual intervention. The machine is equipped with a 6-position tool turret, facilitating a range of cutting, drilling, and threading operations with minimal setup changes. The headstock stroke extends to 80.8 inches, providing ample travel for long workpieces and supporting complex machining sequences. Integrated with an Edge Technologies Scout320 barfeeder, the lathe enables continuous, automated production of bar-fed parts, enhancing throughput and reducing operator involvement. The combination of high spindle speeds, dual-spindle capability, and automated barfeeding makes this machine ideal for high-volume, precision applications in industries such as automotive, medical, and aerospace. The technical specifications reflect a balance of power, speed, and flexibility, ensuring consistent accuracy and repeatability for demanding production environments.
