SW (SCHAUBLIN) BX 621 HORIZONTAL MACHINING CENTER

Technical Description

The SW BX 621 is a 4-axis horizontal machining center featuring robust precision engineering for demanding industrial applications. This machine delivers impressive operational capabilities with X-axis travel of 23.622 inches, Y-axis travel of 20.669 inches, and Z-axis travel of 15.748 inches, accommodating workpieces up to Ø630mm x 1420mm with a maximum weight of 600kg. The system is powered by dual liquid-cooled motorized spindles operating in AC synchronous technology, each generating 69.7 horsepower and achieving maximum spindle speeds of 6,000 RPM. Rapid traverse capabilities reach 60 m/min, enabling efficient cycle times across precision machining operations. The machine accommodates a 40-tool automatic tool changer with HSK-A100 tool taper, supporting maximum tool diameters of 115mm and lengths of 300mm for versatile tool configurations. Control is managed through the SINUMERIK 840D SL CNC system, delivering advanced programming and automation capabilities. The swivelling table features a direct-driven horizontal NC rotary table with counter bearing, providing precision A-axis rotation with exceptional repeatability. The side-by-side spindle arrangement with 600mm spacing enables simultaneous dual-spindle operations for enhanced productivity. This horizontal machining center is ideally suited for aerospace, automotive, and precision component manufacturing where tight tolerances and high-volume production are critical requirements.
