Verdict
Sheet size decides this one. The spindle, the 11 in of Z, the 10-pocket tool changer and the 800 ipm rapids are the same, so choose the Haas GR-712 if the work includes sheet or plate up to 144 × 72 in, and the Haas GR-510 if everything fits its 3,073 x 1,346 mm (121 x 53 in) table. A shop that needs more than 8,100 rpm for small cutters should note that the optional 15,000 and 30,000 rpm spindles are listed for the Haas GR-510 only.
