Our best estimate for the Makino G7 is $380,000 - $520,000. This is an estimate for a cnc grinding machines in this class, not a quote from Makino; configuration, tooling, automation and installation move the final price substantially. A specific price can be requested at https://machinetoolindex.com/machines/makino-g7#price; the request is passed to Makino or an authorised dealer.
Makino names Inconel grinding, nickel-based alloy grinding, root-form grinding and other materials common to aerospace turbine blade-and-vane grinding operations. The machine also mills, drills and taps, so a part can go from milling to grinding without leaving the machine.
Choose by part size. The Makino G5 travels 520 mm (20.5 in) in X, 560 mm (22.0 in) in Y and 600 mm (23.6 in) in Z. The G7 has 690 x 650 x 730 mm (27.2 x 25.6 x 28.7 in), a 535 Ø x 400 SR envelope and 420 mm (16.5 in) HSK tools. Both share the 250 mm (9.8 in) pallet, 12,000 rpm and 120 kg (265 lb) limit.
Rapid traverse and cutting feed are the same: 48,000 mm/min (1,890 ipm) on X and Y, and 43,000 mm/min (1,693 ipm) on Z. Z is the slower axis, which matters most on long Z-direction strokes.
60 tools, each up to 12 kg (26 lb). Diameter is 70 mm (2.8 in), or 220 mm (8.7 in) with limitation. Maximum length is 360 mm (14.2 in) with a CAT shank and 420 mm (16.5 in) with HSK.
