Starrag’s Bumotec 191 Neo Turn-Mill Reduces Tool Change Time

Starrag says its Bumotec 191 Neo seven-axis turn-mill is designed for lean manufacturing, offering  reduced tool change time, faster backworking movement and a higher torque (175 Nm) milling spindle. The result is a machine that is said to enable users to achieve lower piece part costs.

The turn-mill features an ergonomic design that includes large window areas, so operators can clearly see all working zones, as well as well-positioned doors for easy access. The machine can accommodate bar of 42 mm, 50 mm and 65 mm, and has 50 m/min traverse rates for its X, Y and Z axes travels of 410 mm, 200 mm 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 rpm. In addition to milling and turning routines, the 191 Neo can also be used for grinding, polishing, skiving, gear hobbing and diamond cutting with no setup or fixture changes.

The turn-mill is available in four options, including the P model with vice, PRM with multipurpose pickup vice, R with backworking spindle and an RP version with combined vice and backworking spindle.

The company says the machine is very stable during production and offers a 90-position tool magazine that operates in parallel with integrated tool breakage probing. It also features a pallet system and is configured for a robotic, modular or custom-made automated cell. Other options include a temperature-controlled, high-pressure chip conveyor and bar loading.

The machine is said to offer compatibility with the latest production technologies and remote access management, including a touch display with user-friendly and intuitive interface that can be easily and quickly used to swipe between screens. This enables users to monitor the progress of current machining operations, configure programming or track production in real time.
