2020 Bumotec S-191H 7-axis Turn-Mill Center

Description

The machines of the s191H series are suitable for turning, milling and grinding of
individual parts or from bar (diameters: 32, 50 and 65 mm) in a single setting. The series
has an extremely versatile modular structure, which means that it is possible to build any
kind of machines from standardized modules for various machining tasks – including a
machining center with seven axes and three spindles.
The CNC Bumotec s191H Linear turn-mill center is suitable for complete machining of very
complex six sided parts. Linear motors ensure maximum precision and reliable
repeatability in the machining of parts. Thanks to the combination of the rapid linear
drive (acceleration: 1.1 g; speed: 50 m/min) with a high-resolution Renishaw measurement
system (resolution: 1/100 µm) and a stabilized cooling circuit for all heat-generating
elements, the s191H Linear achieves excellent productivity. A unique feature is the
high-speed spindle (150,000 rpm), on which it is possible not only to turn and mill
ceramic parts but, using different grinding discs (measuring 0.5 to 80 mm), they can also
be dry-ground.
