How much does the Ganesh GEN MILL 5X-8 cost?
Price estimate
We do not have a price for the Ganesh GEN MILL 5X-8 that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.
Overview
The GEN MILL 5X-8 puts a tilting rotary table with an 8.34 in (210 mm) platter inside a 40-taper vertical machining center. Expand Machinery calls it a high-speed VMC with a built-in 8 in trunnion. Linear travels are 25.59 in (650 mm) in X, 19.68 in (500 mm) in Y and 17.71 in (450 mm) in Z, so the machine has the envelope of a small 3-axis mill with two rotary axes added on the table.
Part size is set by the trunnion, not by the travels. Maximum part swing is 12.5 in and the table carries 165 lb (75 kg) for rated accuracy. The spindle nose reaches down to the table surface, with a range of 0 - 17.71 in (0 - 450 mm), which lets short tools get to a part tilted on its side.
The spindle is a 12,000 rpm inline direct-drive Big-Plus unit rated 20 HP peak and 15 HP on the 30-minute rating, with 50 ft-lb at 1,500 rpm. Spindles of 15,000 and 24,000 rpm are optional. The maker also lists synchronous rigid tapping and a 300 psi through-the-spindle coolant system with a rotary coupling. X and Y rapid at 1,417 ipm (36 m/min); Z is slower at 944 ipm (24 m/min).
Tool changes take 1.7 sec tool-to-tool with an inverter-driven twin-arm changer. The published tool count for this model is not consistent, so confirm the magazine size when quoting. The machine weighs 12,760 lb (5,788 kg) and occupies 87 x 81 x 113 in (221 x 206 x 288 cm), with 48 in more for the conveyor. The GEN MILL 5X-12 is the next size up, with a 12.6 in (320 mm) platter and 34.64 in (880 mm) of X travel.
