How much does the Ganesh GEN MILL 4024 cost?
Price estimate
We do not have a price for the Ganesh GEN MILL 4024 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
With 40.55 in (1,030 mm) of X travel and a spindle rated 25 HP peak, the GEN MILL 4024 is where Expand Machinery's vertical machining centers turn from light, fast machines into heavier ones. Y travel is 23.62 in (600 mm), Z travel 25.59 in (650 mm), and the machine weighs 15,708 lb (7,120 kg), well above the 11,023 lb (5,000 kg) of the GEN MILL 3120.
The extra iron shows in the ratings. Table load is 3,530 lb (1,600 kg) for full accuracy. Ballscrews are 40 mm, against 32 mm on the GEN MILL 3120, and each axis has a 5 HP (3.5 kW) drive motor. The 12,000 rpm inline direct-drive spindle delivers 90 ft-lb at 1,500 rpm, with 20 HP on the 30 min rating, enough for real roughing in steel with a CAT 40 tool. A 15,000 rpm spindle is an option.
One figure deserves a second look. The table is 45.66 x 19.68 in (1,160 x 500 mm), narrower than the 23.62 in (600 mm) Y stroke. The spindle can therefore travel past both table edges, which helps with overhanging fixtures but means wide plates need support. Z clearance is generous at 5.1 to 30.56 in (130 - 775 mm) from spindle nose to table, and the maker wires the machine for 4th and 5th axes.
Speed is not given up for the mass. Rapids remain 1,417 ipm (36 m/min) in X and Y, the 30+1 twin-arm changer swaps tools in 2.2 sec, and coolant is delivered through the tool at 300 psi (20 bar) from a 97 gallon (367 liter) tank. Accuracy is listed at ±0.0002 in over 12 in. Installation needs 33 kVA and a floor area of 115 x 82 in, with 48 in more on the left for the conveyor.

Frequently Asked Questions
01
The spindle motor is 25 HP peak and 20 HP on the 30 min duty rating, with S1 / S2 / S3 ratings of 11 / 15 / 18.5 kW. Torque is 90 ft-lb at 1,500 rpm. The spindle is an inline direct-drive CAT 40 unit at 12,000 rpm, with BT 40 and 15,000 rpm optional.
02
Travels are 40.55 in (1,030 mm) in X, 23.62 in (600 mm) in Y and 25.59 in (650 mm) in Z. The table is 45.66 x 19.68 in (1,160 x 500 mm) with 5 T-slots of 0.709 in (18 mm) on 100 mm centers, and the maximum table load is 3,530 lb (1,600 kg) for full accuracy.
03
Expand Machinery lists 4th and 5th axis wiring as a feature, and the travel table gives the Z clearance as spindle nose to rotary table surface. The rotary table itself is not part of the listed specification, so the unit and its drive need to be quoted.
04
Coolant capacity is 97 gallons (367 liters) and pressure is 300 psi (20 bar). The feature list names a 300 psi through-the-tool coolant system and a spindle chiller for thermal stability.
05
Listed accuracy for X, Y and Z is ±0.0002 in over 12 in (±0.005 mm over 300 mm travel) and repeatability ±0.0001 in over 12 in (±0.003 mm over 300 mm travel), both to JIS6338. Spindle runout is given as 0.000040 in or less.
