Machine Comparison
Hanwha STL-12 vs Hanwha XD42H
Hanwha vs Hanwha Precision Machinery · Swiss-Type Lathes
Summary
The Hanwha STL-12 and the Hanwha XD42H sit at opposite ends of Hanwha's Swiss-type range. The STL-12 is a small, light machine for miniature parts; the XD42H is a larger machine with a 5.5/7.5 kW main spindle against 2.2 kW (3.0 hp), weighing 4,100 kg (9,039 lb) against 1,800 kg (3,968 lb).
The STL-12 is the faster machine: its main and sub-spindles both reach 10,000 rpm against 6,000 rpm, and its live tools run to 8,000 rpm against 6,000 rpm. It also fits a 1,900 x 1,200 mm floor space where the XD42H needs 2,570 × 1,750 × 1,750 mm. The XD42H's case rests on its spindle power for larger, heavier cuts.
Specifications Comparison
| Specification | Hanwha STL-12 | Hanwha XD42H |
|---|---|---|
| Max Spindle Speed | 10,000 rpm ▲ | 6,000 rpm |
| Spindle Power | 2.2 kW (3.0 hp) | 5.5/7.5 kW ▲ |
| Sub-Spindle Speed | 10,000 rpm ▲ | 6,000 rpm |
| Live Tool Speed | 8,000 rpm ▲ | 6,000 rpm |
| Control | FANUC 32i-B | Hanwha Fanuc-i |
| Machine Weight | 1,800 kg (3,968 lb) | 4,100 kg (9,039 lb) |
| Floor Space | 1,900 x 1,200 mm (74.8 x 47.2 in) | 2,570 × 1,750 × 1,750 mm (101 × 68.9 × 68.9 in) |
Advantages
Hanwha STL-12
- 10,000 rpm main and sub-spindles against 6,000 rpm
- 8,000 rpm live tools against 6,000 rpm
- 1,900 x 1,200 mm (74.8 x 47.2 in) floor space against 2,570 × 1,750 mm
- Lighter machine at 1,800 kg (3,968 lb) against 4,100 kg (9,039 lb)
Hanwha XD42H
- 5.5/7.5 kW main spindle against 2.2 kW (3.0 hp)
- Heavier 4,100 kg (9,039 lb) build for larger-diameter turned parts
- Suited to hydraulic fittings, valve bodies and larger implant bodies
Verdict
These machines serve different jobs. The Hanwha STL-12 suits connector pins, watch parts and small medical screws, where 10,000 rpm spindles and 8,000 rpm live tools matter more than power, and a 1,900 x 1,200 mm footprint saves floor space. The Hanwha XD42H is the choice for larger hydraulic, automotive and orthopedic components that need its 5.5/7.5 kW main spindle. A shop making both kinds of part would likely run one of each.
