Mfg4: High-Speed Air-Driven Spindle

Air-driven spindles achieve variable rotational speed of 100,000-120,000 rpm, enabling existing machines to be cost-effectively upgraded to perform high-speed micro-machining. Tool is driven by air supplied through a stop block or through the machine spindle. Rotation of the machining center spindle isn’t required so the spindle can be used without wear. Due to its ceramic ball bearings and ultra-precise collet system, the runout accuracy of the RBX12 enables ultra-thin wall cutting. The AA-grade Mega Micro Collet guarantees 1//mu//m runout at the collet nose, and the 0.004” (0.100 mm) collapsibility assures a near-perfect concentric clamping of a micro-tool shank. The RBX12 is available with BCV40, BBT30/40 and HSK-A63/F63/E32 interfaces. Models not requiring a stop block have an extremely small body diameter of Ø32mm. For further cost savings, automatic tool change is possible.
