SW BM 1250 HORIZONTAL MACHINING CENTER

Technical Description

The SW BM 1250 is a reconfigurable multi-spindle horizontal machining center engineered for high-precision drilling and milling operations on complex components. This machine features a working envelope of 74.803 inches (X-axis), 49.213 inches (Y-axis), and 19.685 inches (Z-axis), providing substantial capacity for medium to large workpieces. The system is controlled by a SIEMENS SINUMERIK 840D CNC platform, delivering advanced programmability and real-time process optimization. Designed with modular architecture, the BM 1250 accommodates multiple synchronized spindles and reconfigurable milling units, enabling simultaneous multi-axis machining operations including 4 and 5-axis capabilities. The machine incorporates fluid-cooled motor spindles with hybrid bearing technology, ensuring thermal stability and extended tool life during demanding production cycles. Rapid traverse rates reach 60 m/min with axis acceleration capabilities up to 10 m/s², facilitating efficient cycle times and reduced non-cutting time. The workpiece carrier dimensions of 550 mm x 350 mm accommodate diverse component geometries, while hydraulic and pneumatic supply systems (NG 6, max. 250 bar) power auxiliary functions. With positioning tolerance control across X, Y, and Z axes and total machine weight approximately 28,000 kg, the BM 1250 delivers rigidity necessary for precision applications. Originally developed in collaboration with Daimler, this machine represents sophisticated manufacturing technology suitable for automated production environments and complex component geometries requiring exceptional accuracy and repeatability.
