How much does the Hurco HBMx55i cost?
Estimated price range
Our best estimate for a cnc boring machine in this class — not a quote from Hurco. Configuration moves it a long way.
Overview
The Hurco HBMx55i is a boring mill, smaller than the HBMx80i and HBMx120i, with 1,400 x 1,390 x 1,100 mm (55.12 x 54.72 x 43.31 in) of X, Y and Z travel, a 500 mm (19.68 in) W axis and a 1,120 x 1,250 mm (44.09 x 49.21 in) table that indexes through 360° on B and carries 4,000 kg (8,819 lb). The spindle is CAT 50, 2,500 rpm, 30 kW (40.2 hp) and 1,500 Nm (1,106.3 ft-lb).
That torque figure is what a boring mill is for. 1,500 Nm (1,106.3 ft-lb) at low speed drives large boring bars, big face mills and heavy drills through steel and cast iron, where a high-speed spindle such as the 118.9 Nm (87.7 ft-lb) unit on the BX50i would stall. The 2,500 rpm ceiling is the other side of that choice: small cutters and aluminium are not what this machine is for.
The B axis turns the table through 360°, so four sides of a housing, gearbox case or valve body can be bored and faced in one setup, with bores on opposite faces lined up off the same datum. The W axis adds 500 mm (19.68 in) of reach along the spindle line on top of the 1,100 mm (43.31 in) of Z, which helps on deep bores.
The 60-tool magazine handles tools up to 300 mm (11.8 in) long and 25 kg (55.1 lb). Tool-to-tool time is 15 sec, which is slow for short operations but small against the long cuts typical of boring-mill work. The HBMx80i steps up to 2,000 x 1,780 x 1,650 mm (78.74 x 70.08 x 64.96 in), a 1,440 x 1,600 mm (56.69 x 62.99 in) table for 6,300 kg (13,889 lb) and 400 mm (15.7 in) tools on the same spindle. The HBMx55i weighs 19,200 kg (42,328 lb) and runs Hurco's WinMax control, with conversational and NC programming.

Strengths & Limitations
Strengths
- 1,500 Nm (1,106.3 ft-lb) from a CAT 50 spindle rated 30 kW (40.2 hp)
- 360° B-axis table of 1,120 x 1,250 mm (44.09 x 49.21 in) for four-sided work in one setup
- 500 mm (19.68 in) W axis in addition to 1,100 mm (43.31 in) of Z for deep bores
- Table rated for 4,000 kg (8,819 lb)
- 60-tool magazine taking tools up to 25 kg (55.1 lb)
Limitations
- Top speed of 2,500 rpm rules out small cutters and high-speed aluminium work
- Tool-to-tool time of 15 sec adds up on jobs with many short operations
- Maximum tool length is 300 mm (11.8 in), against 400 mm (15.7 in) on the HBMx80i
- Weighs 19,200 kg (42,328 lb), so it needs a prepared foundation and rigging

Frequently Asked Questions
01
Both have the same CAT 50, 2,500 rpm spindle with 1,500 Nm (1,106.3 ft-lb) and 60 tools. The HBMx80i has 2,000 x 1,780 x 1,650 mm (78.74 x 70.08 x 64.96 in) of travel and a 1,440 x 1,600 mm (56.69 x 62.99 in) table for 6,300 kg (13,889 lb). The HBMx55i has 1,400 x 1,390 x 1,100 mm and a 1,120 x 1,250 mm table for 4,000 kg (8,819 lb).
02
It is a separate 500 mm (19.68 in) axis along the spindle line, on top of the 1,100 mm (43.31 in) of Z travel. The extra reach matters on deep bores and on features far from the face the part is set up against.
03
The magazine holds 60 CAT 50 tools, each up to 300 mm (11.8 in) long and 25 kg (55.1 lb). Tool-to-tool time is 15 sec.
04
The BX50i is a high-speed machine, with a 20,000 rpm HSK-63A spindle giving 118.9 Nm (87.7 ft-lb) and no rotary axis. The HBMx55i runs to 2,500 rpm with 1,500 Nm (1,106.3 ft-lb), indexes on a 360° B axis and carries 4,000 kg (8,819 lb) against 2,000 kg (4,409 lb) on the BX50i.
