The BM-Q model is fitted with a Ø200mm W axis quill for improved reach and has a BBT50 face/taper contact spindle running at 6000rpm, developing 1600N.m of torque using a 30kW motor. The spindle is cooled using a chiller unit and a high power spindle is available for heavier cutting.

The BM-U model is fitted with a rotary A axis head with a spindle speed of 12000rpm, driven by a 64kW motor developing 236N.m of torque. The head indexes at ±95º from the horizontal plane presenting an angular approach to workpieces for compound work and providing improved tool clearance.

The BM-H high speed model is fitted with an HSK63A spindle running at a speed of up to 20000rpm. The spindle is driven by a 51kW motor developing 89N.m of torque.

The 35000kg machine mass is indicative of its robust and rigid structure and, as a result of careful structural design based on overt 40 years of experience on building machining centres, Toshiba have kept the BM-Q size down to 5.5M wide and 8M deep resulting in a low 800kg/M² floor loading.
