TORNOS SIGMA 20/6 CNC LATHE

Technical Description

This machine is equipped with a **Fanuc 31i-B CNC control**, a high-performance system ideal for multi-axis precision machining. It features a **Z-travel of 9.06 inches** and supports a **maximum turning/cutting length of 9.10 inches**, with a **maximum cutting/turning diameter of 1.00 inch** and a **bar capacity of 0.80 inch**. The spindle system includes a **primary spindle motor of 5 HP capable of speeds up to 10,000 RPM**, and a **secondary spindle motor also rated at 5 HP** with a maximum speed of **6,000 RPM**, enabling versatile multi-spindle operations. The tool turret supports **14 tool positions** to facilitate complex tooling setups. Additionally, the machine offers **live milling capabilities at speeds up to 10,000 RPM**, enhancing its multifunctional machining ability. The Fanuc 31i-B control is well-known for its ultra-high-speed processing and advanced motion control algorithms that improve accuracy and surface finish through nanometer-level resolution and high-speed interpolation. It supports simultaneous control of multiple axes and spindles, allowing for efficient and precise machining of complex parts. Integrated features such as advanced trajectory control and automatic filtering minimize cycle times and machining errors, optimizing both speed and quality. This CNC control system combines robust hardware performance with intelligent software to accommodate high-grade machining centers and advanced multi-axis applications.
