NAKAMURA-TOME STW-40 HORIZONTAL MACHINING CENTER

Technical Description

The Nakamura-Tome STW-40 Horizontal Machining Center is a versatile twin-spindle turn-mill center featuring two main spindles, each with 40 HP power and 3,500 RPM max speed, capable of handling a turning diameter up to 22.44" and bar capacity of 2.79". It incorporates dual turrets, each supporting 12 turning and 12 rotary tools, with rotary tools powered at 7.5 HP and 3,600 RPM, enabling up to three simultaneous cutting tools for complex multi-axis machining. The machine operates on 11 programmable axes, including standard milling and drilling functions with ‘C’ and ‘Y’ axis capabilities, providing highly precise, multi-functional machining. The X, Y, and Z axes offer travels of 24.41", 7.87", and 21.65", respectively, each with rapid traverse rates up to 985 ipm, supporting high-speed production. The system uses a FANUC 16i control unit optimized for tool and motion coordination, facilitating efficient setup and execution of intricate parts. Its adaptability includes secondary milling/drilling on and off-center, and a high-performance turret system enhances tool change speed and capacity. The machine is designed to deliver dynamic, twist-resistant machining with comprehensive tool capacity and power to handle demanding turning and milling tasks in a single compact footprint. This combination makes the STW-40 ideal for precision manufacturing environments requiring integrated turning and machining operations with high productivity and flexibility.
