STARRAG GROUP has developed a new version of its Bumotec 191 mill/turn machining center – the Bumotec 191neo – building on its reliability, performance, and modularity and housing the operation in an ergonomic enclosure.
The Bumotec 191neo presents a large area of windows and perfectly positioned access doors, for high visibility of the different zones within the machine, and accessibility for all operators.
The touch-display man-machine interface, developed from a Windows-based PC application, can be used to swipe easily between screens. Among other functions, it can be used to monitor the progress of current machining operations, configure the programming, or track production in real time.
The new approach defined in conjunction with representative operators ensures training is user-friendly and intuitive also with the objective of reducing the level of skills of operators.
The Bumotec 191neo is available in four versions –
• "P" with a vice,
• "PRM" with multipurpose pickup vice,
• "R" with back- working spindle, and
• "RP" with a combined vice and back-working spindle
– and a choice of bar passage diameters of 42, 50 or 65 mm (1.6, 1.9, 2.5 inches.) There are twelve (12) separate machines based on a single platform, according to the developer.
The Bumotec 191neo provides an economical and technical solution to both current and future challenges arising from specific requirements relating to medical technologies and also the micromechanics sector.
Offering stable production without any intervention from operators, the 191neo achieves impressive productivity. Tool-changing time has been reduced by 15%, and to this is added a Starrag-developed/produced milling spindle with higher torque, as well as a back-working movement controlled by an electric motor, 12% faster and with rigid, precise position control.
As has long been standard for Bumotec, its tool magazine has 90 positions and integrates now a tool breakage probe that runs in parallel. Coupled with the now traditional Bumotec palletizer or with a robotic, modular or custom-made automated cell, this means the 191neo is available for "24/7" production, interrupted only by preventive maintenance.
Equipped with "à la carte" peripherals, such as a temperature-controlled, high-pressure chip conveyor, and a Bumotec or other commercially-available bar loader, the modular nature of the 191neo ensures all customer needs can be met. In addition to milling and turning, it can also be used for grinding, polishing, skiving, gear hobbing, and diamond cutting, thereby allowing complex, demanding parts to be completed without changing fixtures.Learn more at www.starrag.com
