Bumotec lathe boasts Swiss precision

Working within a compact envelope of 410 by 200 by 400 mm in X, Y and Z-axis, respectively, the S191 has an accuracy of +/-0.0001 mm. A rotational C-axis and a swivelling B-axis have angular travel of -25 to +120° and an accuracy level of 0.001°. The combination of accuracy and multi-axis capability delivers a machine tool with the ability to machine the most complex of parts to the tightest of tolerances, making the S191F the machine of choice for medical, aerospace, automotive, mould and die, and micro-machining applications. The S191 is available in four configurations with an F, FL, FT and FTL version available. The S191F and S191FL are multi-axis milling centres, while the S191FTL and S191FT are mill/turn centres, with an A-axis that sits under the workpiece, as opposed to the W-axis on the S191F and S191FL machines. Further highlights are 40 m/min travel in X, Y and Z axis, with an acceleration of 8m/s. For increased material removal and the machining of difficult components, the 36,000 rpm swivelling B-axis has a 4.3 kW motor, while the main C-axis spindle has 90,000 rpm rotational speed with a direct drive power of 7.5 kW. This combination of power and speed makes the S191 well suited to mould and die machining, and the production of small intricate components. The A-axis on the on the FT and FTL versions has a 7.5 kW motor, with a spindle speed of up to 5,500 rpm and a robust clamping force of 8,500N. The W-axis on the S191F and S191FL delivers 310 mm axis travel at a speed of 40 m/min. To further increase productivity and capability, the S191 has 30 tool carousel with the option of 60 tools feeding an HSK40 spindle. The machine has a tool change time of 3.2 seconds.
