Hurco HBMx120i vs Hurco HBMx55i
Hurco vs Hurco · CNC Boring Machines
Summary
The Hurco HBMx120i and Hurco HBMx55i are CNC boring machines from the same Hurco range, but they are different size classes and serve different jobs. Both use a CAT 50 spindle with 2,500 rpm, 30 kW (40.2 hp) and 1,500 Nm (1,106.3 ft-lb), 60 tools and a 15 sec tool change.
The HBMx120i is the long-bed machine: 3,000 mm (118.11 in) of X travel against 1,400 mm (55.12 in), 1,780 mm (70.08 in) of Y against 1,390 mm (54.72 in), and 1,650 mm of Z against 1,100 mm (43.31 in). It carries a 1,440 mm (56.69 in) × 1,600 mm (62.99 in) table against 1,120 mm (44.09 in) × 1,250 mm (49.21 in), rated for 6,300 kg (13,889 lb) against 4,000 kg (8,819 lb). The HBMx55i is the lighter machine at 19,200 kg (42,328 lb) against 25,500 kg.

Advantages
Hurco HBMx120i
- 3,000 mm (118.11 in) of X travel against 1,400 mm (55.12 in)
- 1,780 mm (70.08 in) of Y and 1,650 mm of Z against 1,390 mm (54.72 in) and 1,100 mm (43.31 in)
- 6,300 kg (13,889 lb) table load against 4,000 kg (8,819 lb)
- 1,440 mm (56.69 in) × 1,600 mm (62.99 in) table against 1,120 mm (44.09 in) × 1,250 mm (49.21 in)
Hurco HBMx55i
- Lighter machine: 19,200 kg (42,328 lb) against 25,500 kg
- The same 1,500 Nm (1,106.3 ft-lb) spindle and 60 tools in a machine sized for housings up to 4,000 kg (8,819 lb)
Verdict
Choose by part length. The Hurco HBMx120i is for long frames, beds and weldments that need boring along 3,000 mm (118.11 in) of X, or several parts set along X and machined in one cycle, up to 6,300 kg (13,889 lb). The Hurco HBMx55i suits large steel and cast iron housings up to 4,000 kg (8,819 lb) that fit within 1,400 mm (55.12 in) of X. Spindle and tooling are identical, so size is the whole decision.
