Mill-Turn Center Features High-Torque Spindle

Starrag UK has released the Bumotec 191neo seven-axis mill-turn center, said to offer low-cost machining of complex, higher-value parts for industries such as medical devices, luxury goods and micromechanics. The company says this machining center offers a 15% reduction in tool change time, 12% faster back-working movement and a higher torque milling spindle (175 Nm).

The Bumotec 191neo features ergonomic design that includes large window areas so operators can see all working zones, as well as intentionally positioned doors for ease of access. The machine can accommodate bar lengths of 42, 50 and 65 mm, and has 50 m/min traverse rates for its X, Y and Z axes with travels of 410, 200 and 400 mm, respectively.

Main spindle options extend up to 22 kW with a torque rating of 175 Nm, while the 15 kW/36 Nm subspindle operates at 6,000 revs/min. The machine is designed to also be used for grinding, polishing, skiving, gear hobbing and diamond cutting with no setup or fixture changes.

Starrag UK offers four options — P model with vice; PRM with multipurpose pickup vice; R with back-working spindle; and RP version with combined vice and back-working spindle.

Like its predecessor, the machine is designed for extreme stability during production. With a 90-position tool magazine that operates in parallel with integrated tool breakage probing, plus a pallet system and configurations for a robotic, modular or custom-made automated cell, users have access to 24/7 production regimes. Other options include temperature-controlled, high pressure chip conveyor and bar loading.

The machine also features a touch display with an interface designed for ease of use that enables users to swipe between screens to, for instance, monitor the progress of current machining operations, configure programming or track production in real time.
