Ganesh GEN MILL 3120

Q: How much does the Ganesh GEN MILL 3120 cost?

The price estimate for the Ganesh GEN MILL 3120 is uncertain: we have no price for it that we can cite and no estimate we can stand behind, so we give no figure. Configuration, tooling, automation and installation move the final price substantially. A specific price can be requested at https://machinetoolindex.com/machines/ganesh-gen-mill-3120#price; the request is passed to Ganesh or an authorised dealer.

Q: What size work fits the GEN MILL 3120?

Travels are 31.496 in (800 mm) in X and 19.685 in (500 mm) in Y and Z. The table is 37.40 x 19.68 in (950 x 500 mm), has 3 T-slots of 18 mm on 100 mm centers and carries 1,323 lb (600 kg). Spindle nose to table is 4.72 - 24.40 in (120 - 620 mm).

Q: Which control does it use?

Expand Machinery lists a Mitsubishi M830 CNC control with 2,700 block look-ahead for this model. Look-ahead of that depth matters on 3D surfacing programs made of many short moves, where the control must plan feed across blocks to hold a steady speed.

Q: What equipment does the feature list name for the GEN MILL 3120?

A 30-tool high-speed twin-arm tool changer, 300 psi through-the-spindle coolant with a rotary union, a chip wash-down system, a belt-type chip conveyor with a 38 in barrel-height discharge and a full enclosure with top covers and a precut exhaust duct.

Q: How does it compare with the GEN MILL 4024?

The GEN MILL 4024 is larger and heavier: 40.55 in (1,030 mm) of X, 23.62 in (600 mm) of Y, a 3,530 lb (1,600 kg) table load and 15,708 lb (7,120 kg) of machine weight. The GEN MILL 3120 has 31.496 in (800 mm) of X, carries 1,323 lb (600 kg) and weighs 11,023 lb (5,000 kg). Both have 30+1 tools and a 2.2 sec tool change.

Q: What are the tool limits?

Maximum tool diameter is 5.90 in (150 mm), reduced to 3.15 in (80 mm) when adjacent pockets are occupied. Maximum tool length is 11.81 in (300 mm) from the gage line and maximum tool weight is 15 lb (7 kg). The shank is CAT 40, with BT 40 optional.

Price estimate

Uncertain

We do not have a price for the Ganesh GEN MILL 3120 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 3120 is a 40-taper vertical machining center with travels of 31.496 in (800 mm) in X and 19.685 in (500 mm) in both Y and Z. It is the general-purpose size of the line: large enough for two vises or a fourth-axis setup, and it keeps the 2.2 sec tool change of the compact GEN MILL 2416.

Its table is 37.40 x 19.68 in (950 x 500 mm) and rated for 1,323 lb (600 kg). The spindle nose sits between 4.72 and 24.40 in (120 - 620 mm) above the table, and the throat is 20.27 in (515 mm). The table is as wide as the Y stroke, so the whole surface can be reached.

Expand Machinery spells out the equipment of this model in its feature list. The spindle is a 12,000 rpm direct-drive beltless unit, with 15,000 rpm optional. Through-the-spindle coolant at 300 psi with a rotary union is named, along with a chip wash-down system, a belt-type chip conveyor that discharges at a 38 in barrel height, and a full enclosure with top covers and a precut exhaust duct. The control is a Mitsubishi M830 with 2,700 block look-ahead.

The 30+1 twin-arm changer accepts tools up to 11.81 in (300 mm) long and 15 lb (7 kg). X and Y rapid at 1,417 ipm (36 m/min) and Z at 1,260 ipm (32 m/min). The table here carries no spindle power or torque figure, so ask for the motor rating in writing before ordering. The machine weighs 11,023 lb (5,000 kg) and needs 25 kVA.
