Our best estimate for the Haas GR-712 is $193,995 - $250,000. This is an estimate for a vertical machining centers (vmc) in this class, not a quote from Haas Automation; configuration, tooling, automation and installation move the final price substantially. A specific price can be requested at https://machinetoolindex.com/machines/haas-gr-712#price; the request is passed to Haas Automation or an authorised dealer.
Haas no longer lists the GR-712. Its product page has been removed from the Haas website, and the figures on this page were read from that page before it was taken down. For a new machine with the same 144 × 72 in table size, the GM-2 is the model to look at.
Both have a 144 × 72 in table rated for 6,000 lb. The GR-712 is listed with 145 × 85 × 11 in of travel, a 15 hp spindle and a 10-tool carousel. The GM-2 has 145 × 87.5 × 22 in (3,683 × 2,223 × 559 mm) of travel, a 30 hp (22.4 kW) spindle and a 30+1 tool changer. On X the GR-712 is listed at 800 ipm and the GM-2 at 472 ipm (12 m/min).
The listed tool changer is a 10-tool carousel for CT or BT 40 holders. Maximum tool diameter is 3.5 in and maximum tool weight is 12 lb. The table gives no maximum tool length, so check that against the 11 in of Z travel and the 2.5 in minimum distance from spindle nose to table.
The listed shipping weight is 24,000 lb, or 24,200 lb with the EC option and 24,600 lb with the EZ24 option; the table does not explain what those options are. The domestic pallet is listed at 226 × 137 × 116 in. Power is 220 VAC three-phase at 40 A or 440 VAC at 20 A, and air is 4 scfm at 100 psi with an 80 psi minimum.
