Supplied in the UK by Starrag UK, the s100multi is complemented by a range of machining centres, turn-mill centres and horizontal transfer machines. All utilise the high rigidity, vibration damping and static counterweight characteristics of machine construction based on a cast iron base and frame for the high-accuracy production of components for industry sectors that also embrace connector, dental and automotive.


The Bumotec range includes: S-191 mill-turn machines — 15 kW main spindle/8 kW milling spindle; bar capacities of 32 mm to 65 mm and axes strokes of 410 mm (X), 200 mm (Y) and 400 mm (Z), rapids up to 50 m/min (with linear drives option) and 30-tool ATC as standard (60 or 90 optional). The target is the single set-up machining of up to six- sided complex parts.


The mill-turn range also embraces S-128 five-axis units and S-189 twin-turret machines with bar capacities of 42 mm and 65 mm, eight axes and sub-spindle.


S-191V machining centre is available in three-, four- and five-axis versions for complex one-hit machining. It features linear drives and motors, up to 13 kW main spindle motors, 50 m/min traverse rates on axes of up to 410 mm by 200 mm by 400 mm and 30-, 60 or 90-tool automatic toolchangers.


S-1000 horizontal transfer machines have multi stations and axes: stations 1-7 for four-axis machining ; station 8 for cut-off ; station 9 for three-axis ‘re-taking’ for machining of six-sided workpieces; and station 10 a two-axis bar feed. The automatic bar feed can accommodate nine bars, and the two horizontal and two vertical spindles can both accommodate 47 mm diameter bar.


S-90 three-/four-axis multi-spindle milling machines have up to nine tools and simultaneous C axis having automatic tilt from 0 to 20 degrees.
