Makino N2-5XA

The Makino N2-5XA is a small 5-axis horizontal machining center designed for near-net-shape components: medical parts such as orthopedic implants and surgical support devices, and aero-engine components. It works on a 200 mm ø (7.87 in Ø ) pallet with 300 mm (11.8 in) of X, 300 mm (11.8 in) of Y and 230 mm (9.1 in) of Z, and Makino states it occupies 54 square-feet of floor space.

The two rotary axes are direct drive and sit in a trunnion casting: A covers 160° (-120° ~ +40°) and B turns 360° (unlimited). Makino's case for the layout is access to the workpiece and the chance to consolidate operations into fewer setups. The listed maximum workpiece is 300 mm Ø x SR270 mm (with limitations), 11.8 in Ø x SR10.6 in, and no more than 30 kg (66 lb), which fixes the machine firmly on implant- and blade-sized parts.

The spindle is a 20,000 rpm HSK-A40 unit that, according to Makino, reaches maximum speed in 0.8 seconds, and it comes with a standard 320 psi through-spindle coolant system. Makino also lists as standard the Pro6 control with Super Geometric Intelligence (SGI) for contour machining, and quotes 1.4G of Z-axis acceleration. Rapids are 42,000 mm/min on X and Y and 56,000 mm/min on Z (1,653 ipm (X / Y), 2,205 ipm (Z)), and cutting feed reaches 32,000 mm/min (1,259.8 ipm).

The magazine holds 36 tools, each up to Ø50 x 180 mm (Ø 1.97 in x 7.09 in) and 2 kg (4.4 lb). Chip-to-chip time is 4.9 sec. A lift-up chip conveyor with a permanent media drum filter and a cyclonic coolant filter is standard.
