Overview
The Hurco VMX84i is the largest machine in the VMX series, offering a massive 2,134 x 864 x 610 mm (84 x 34 x 24 in) travel envelope. At 84 inches of X-axis travel and 34 inches of Y, this machine handles workpieces that most job shop VMCs can't touch — 7-foot-long parts, wide mold bases, and multi-fixture setups that would need a horizontal boring mill on a smaller platform.
The spindle runs 12,000 RPM through a Big Plus CAT 40 taper producing 13.4 kW (18 hp) and 213 Nm (157 ft-lbs) of torque. Putting a 40-taper spindle on an 84-inch machine is a clear signal about intended use: this is an aluminum and light-material machine. If you need to hog steel across 84 inches, step up to the VMX84i-50T. For aerospace aluminum, long extrusions, and large plate work, the 40-taper's 12K RPM is an advantage.
Table dimensions are 2,134 x 864 mm (84 x 34 in) with a 3,000 kg (6,614 lb) max load. That 84x34-inch table is genuinely huge — large enough for full fixture plates serving an entire product family. The 40-tool ATC keeps changeovers fast despite the massive travel distances.
The VMX84i uses roller linear guides on X and Y with box way on Z. Rapids are 30 m/min (1,181 ipm) on X, 27 m/min (1,063 ipm) on Y, and 24 m/min (945 ipm) on Z. Moving the spindle 84 inches at these rapids takes about 4.5 seconds, which adds up in cycle time for parts that use the full travel.
At approximately 13,000 kg (28,660 lb), the VMX84i is a major installation. It requires a dedicated concrete pad, rigging equipment for positioning, and careful leveling across the full 84-inch base. Thermal stability across a base this long requires a temperature-controlled shop environment for tight tolerance work. WinMax control is standard.
Pricing runs $200,000-$260,000 new. Used machines are uncommon due to lower production volumes, but when available, 2016-2021 models trade in the $120,000-$180,000 range.

Strengths & Limitations
Strengths
- 2,134 mm (84 in) X-travel handles 7-foot-long workpieces in a single setup
- 864 mm (34 in) Y-travel enables wide multi-vise setups and large plate machining
- 3,000 kg table load supports heavy fixtures and large workpieces
- 40-taper tooling keeps operating costs manageable on a machine this large
- 12K RPM spindle speed optimized for high-speed aluminum cutting across the full envelope
- 13,000 kg machine weight provides stability across the massive travel range
Limitations
- 18 hp spindle is significantly underpowered for heavy steel work on a machine this large
- 13,000 kg weight requires a dedicated concrete foundation pad and professional rigging
- Enormous footprint demands substantial shop floor space — plan for 6+ meters in X
- Thermal management across an 84-inch base requires a temperature-controlled shop for tight work
- 40-taper limits material removal rate — the 50T version is necessary for steel-heavy applications

Frequently Asked Questions
01
New base price starts around $200,000. Fully configured with through-spindle coolant, probing, chip conveyor, thermal compensation, and options, expect $230,000-$260,000. Used machines are uncommon but trade in the $120,000-$180,000 range.
02
For aluminum, absolutely. At 12K RPM with small to mid-size carbide endmills, 18 hp moves aluminum efficiently across the full travel range. For steel, no — the VMX84i-50T with 25 hp and CAT 50 torque is the right choice. The 40-taper VMX84i is purpose-built for light-material, high-speed work.
03
At 13,000 kg, plan for a minimum 12-inch reinforced concrete pad, isolated from surrounding floor vibration. The pad should extend 2-3 feet beyond the machine footprint on all sides. Professional rigging is required for installation — this is not a machine you move with a forklift.
04
The VMX84i uses a standard C-frame VMC architecture with a moving table, while bridge and gantry mills use a fixed table with a moving bridge. The C-frame design is more affordable and rigid for this travel range. Bridge mills start making sense above 120 inches of travel or for very heavy workpieces.
05
Yes, with proper installation and thermal management. The one-piece base casting maintains geometric accuracy across the full travel, but thermal growth from shop temperature changes can introduce positional error over 84 inches. Keep shop temperature within ±3°F during machining for best results.
