Overview
The Hurco HBMx120i is the largest horizontal boring mill in Hurco's lineup, built for shops machining the biggest castings, weldments, and structural components that require extreme table capacity and spindle reach. With a 2,200 x 1,800 mm (86.6 x 70.9 in) table, 75 kW (100 hp) spindle, and 700 mm W-axis quill travel, it's the machine for workpieces that exceed the capacity of the HBMx80i.
The horizontal spindle delivers 75 kW (100 hp) at up to 2,000 RPM through a BT50 taper, providing maximum torque for the largest boring bars, face mills, and roughing operations. At 2,000 RPM max speed, the spindle is optimized for heavy cutting rather than high-speed finishing — this is a machine built to move metal on massive parts. The 700 mm (27.6 in) W-axis quill extends deep into large castings and housings.
X-axis travel is 2,200 mm (86.6 in), Y-axis is 1,600 mm (63 in), and Z-axis is 1,300 mm (51.2 in). The rotary B-axis table indexes for multi-face machining, and the table supports up to 10,000 kg (22,046 lb) of workpiece weight. This load capacity handles the heaviest castings and weldments found in mining, energy, marine, and heavy equipment manufacturing.
The 60-tool automatic tool changer provides capacity for complex multi-operation jobs that involve many boring, milling, drilling, and tapping tools across multiple faces. Rapid traverse runs at 15 m/min on linear axes. Machine weight is approximately 35,000 kg (77,162 lb), requiring serious foundation planning.
The WinMax conversational control is arguably most valuable on a machine this size, where single parts can require full-day programming sessions in G-code. WinMax's conversational approach lets experienced operators define complex multi-face boring operations in a fraction of the time. The HBMx120i competes with the Kuraki KBT-15A, TOS WHN 130, SNK BP-130.40, and similar large-table horizontal boring mills.

Strengths & Limitations
Strengths
- 10,000 kg table load capacity handles the heaviest castings and weldments in industrial manufacturing
- 100 hp spindle with 700 mm W-axis quill provides maximum power and reach for deep boring on the largest workpieces
- 2,200 mm X-travel and 1,600 mm Y-travel accommodate workpieces too large for standard boring mills
- 60-tool ATC handles complex multi-face jobs without running out of tool positions
- WinMax conversational control saves the most time on the largest, most complex boring mill jobs
- B-axis rotary table enables complete multi-face machining of large castings in a single setup
Limitations
- Major capital investment requires consistent heavy workload to justify the machine cost
- 35,000 kg machine weight requires engineered foundation and heavy crane infrastructure
- 2,000 RPM max spindle speed is optimized for heavy boring — not suitable for high-speed finishing
- 15 m/min rapid traverse adds significant non-cutting time on programs with many positioning moves
- Large floor space requirement may exceed available space in smaller facilities

Frequently Asked Questions
01
A new Hurco HBMx120i typically sells between $650,000 and $850,000 depending on options including probing, through-spindle coolant, right-angle heads, chip conveyors, and enhanced chip management systems. Installation and foundation costs add to the total investment.
02
At 35,000 kg, the HBMx120i requires an engineered reinforced concrete foundation capable of supporting the machine weight plus 10,000 kg of workpiece load. Foundation design must account for dynamic cutting forces. Hurco provides detailed foundation drawings. Installation requires 15-ton or larger crane capacity.
03
The HBMx120i steps up with a larger table (2,200 x 1,800 mm vs 1,800 x 1,500 mm), more axis travel, 100 hp spindle (vs 84 hp), 700 mm quill (vs 600 mm), 10,000 kg table load (vs 6,000 kg), and 60-tool ATC (vs 40). It handles significantly larger and heavier workpieces at a higher price point.
04
Yes. Right-angle milling heads extend the machine's capability to surfaces perpendicular to the main spindle axis. On a machine this size, right-angle heads are often essential for reaching features inside deep cavities and on surfaces that the horizontal spindle cannot access directly.
05
The HBMx120i is a table-type boring mill with a 10,000 kg table load limit. Floor-type boring mills can handle even larger workpieces by mounting them on a stationary floor plate. For workpieces exceeding 10,000 kg, a floor-type machine is required. The HBMx120i offers the advantage of integrated table rotation for indexed multi-face machining.
06
Mining, energy (oil and gas, power generation), marine, heavy construction equipment, and defense. These industries produce the large castings and weldments that require the HBMx120i's table capacity, spindle power, and quill reach. Many shops running this class of machine are contract manufacturers serving multiple heavy industries.
