Hurco VMX84i-50T

The Hurco VMX84i-50T is the flagship of Hurco's VMC lineup — the largest travel envelope paired with the most powerful spindle the company offers in a vertical machining center. With 2,134 x 864 x 610 mm (84 x 34 x 24 in) of travel and a CAT 50 spindle, it's built for shops that need to move serious steel across very large workpieces.

The spindle runs 10,000 RPM through a Big Plus CAT 50 taper producing 18.5 kW (25 hp) and 358 Nm (264 ft-lbs) of torque. On an 84-inch machine, that torque is essential — face milling a 3-foot-wide steel mold base with a 5-inch shell mill requires sustained torque that a 40-taper can't deliver. The Big Plus dual-contact interface adds rigidity at the spindle nose, which is critical when running large-diameter inserted cutters.

Table dimensions are 2,134 x 864 mm (84 x 34 in) with a 3,500 kg (7,716 lb) max load. The 84x34-inch table with 3.5-ton capacity handles serious iron. The 40-tool ATC manages CAT 50 toolholders, though at this machine size, some shops add a second tool storage unit for extended unattended operation.

Construction follows the hybrid guide design — roller guides on X and Y, box way on Z. Rapids are 27 m/min (1,063 ipm) on X, 24 m/min (945 ipm) on Y, and 22 m/min (866 ipm) on Z. These are slower than the 40-taper version due to the heavier spindle head, but for the applications this machine serves, rapid traverse speed is rarely the cycle time bottleneck.

At approximately 14,000 kg (30,865 lb), the VMX84i-50T is a 15-ton machine that requires professional installation planning. Foundation design, floor loading, rigging access, and utility connections all need to be engineered before the machine arrives. WinMax control is standard, though at this level, most programming is done in CAM.

Pricing runs $220,000-$280,000 new. Used machines are rare in the secondary market. When available, 2016-2021 models trade in the $140,000-$200,000 range. This machine competes with large-format VMCs from Mazak, Okuma, and Johnford.
