Technical Description
The BUMOTEC S-191 Linear Horizontal Machining Center is a high-precision, multi-tasking mill-turn solution designed for complex, six-sided part production in a single setup. Featuring a main spindle with a maximum turning diameter of 4.000" and a bar capacity of 2.550", it supports turning lengths up to 15.000" and is equipped with a 4.000" chuck. The main spindle delivers 20 HP at 6,000 RPM, while the sub-spindle offers 10 HP at 5,500 RPM, enabling efficient secondary operations. The machine integrates a swivel tool spindle as the primary tool carrier, supporting up to 30 turning and 30 rotary tools, with the rotary tool capable of 17.3 HP and 40,000 RPM for high-speed milling and grinding. With 5 standard axes (expandable to 6), the S-191 Linear provides X, Y, and Z axis travels of 15.700", 7.870", and 16.100" respectively, all driven by linear motors for rapid traverse and feed rates of 1,965 ipm, ensuring exceptional speed and accuracy. The system allows for one simultaneous cutting tool, optimizing process reliability. Advanced thermal management, high-resolution measurement systems, and a stabilized cooling circuit contribute to micron-level precision and repeatability. The S-191 Linear is ideal for complete machining of complex components from bar or blanks, supporting turning, milling, grinding, drilling, and deburring with minimal operator intervention and maximum productivity.
