How much does the Hanwha STL-12 cost?
Estimated price range
Our best estimate for a swiss-type lathe in this class — not a quote from Hanwha. Configuration moves it a long way.
Overview
The Hanwha STL-12 is a small Swiss-type lathe for bar up to 12 mm (0.472 in), with a main and a sub spindle that both reach 10,000 rpm and up to 16 tool positions. The listed figures give a maximum turning length of 150 mm (5.91 in).
Power is in keeping with the bar size: 2.2 kW (3.0 hp) on the main spindle and 1.5 kW (2.0 hp) on the sub spindle. Both spindles have a C axis and the live tools run to 8,000 rpm, so cross holes, flats and slots can be finished on either end of the part before it leaves the machine.
The table lists 5 axes as standard, with a Y axis as an option. Anyone who needs off-centre milling or drilling should confirm that a particular machine has the Y axis fitted, because it is not part of the base configuration. The guide bushing is standard and a GBL option is listed beside it. The control is a FANUC 32i-B.
This is a light machine on a small footprint, 1,800 kg (3,968 lb) and 1,900 x 1,200 mm (74.8 x 47.2 in). The XD20 II, for comparison, weighs 2,700 kg (5,952 lb) and takes 20 mm (0.79 in) stock. Listed positioning accuracy for the STL-12 is ±0.003 mm.

Strengths & Limitations
Strengths
- Main and sub spindle both run to 10,000 rpm, which small-diameter bar needs to reach a workable surface speed
- C axis on both the main and the sub spindle, with live tools to 8,000 rpm for milled and cross-drilled features
- Compact: 1,900 x 1,200 mm (74.8 x 47.2 in) footprint and 1,800 kg (3,968 lb)
- Up to 16 tool positions, and a guide bushing as standard with a GBL option listed
- Listed positioning accuracy of ±0.003 mm
Limitations
- Bar capacity stops at 12 mm (0.472 in); larger stock needs a bigger machine such as the XD20 II at 20 mm (0.79 in)
- The Y axis is an option on top of the 5 standard axes, so off-centre work depends on how a given machine was ordered
- Spindle power is 2.2 kW (3.0 hp) main and 1.5 kW (2.0 hp) sub, which rules out heavy cuts in tough alloys
- Maximum turning length is 150 mm (5.91 in), so longer parts are outside its range

Frequently Asked Questions
01
The listed maximum bar capacity is 12 mm (0.472 in) and the maximum turning length is 150 mm (5.91 in). A guide bushing is standard, and the table also lists a GBL option.
02
Only as an option. The listed figures give 5 axes as standard with the Y axis optional, plus a C axis on both the main and the sub spindle. If a job needs off-centre drilling or milling, confirm that the specific machine has the Y axis.
03
The main spindle and the sub spindle are both listed at 10,000 rpm, with 2.2 kW (3.0 hp) on the main and 1.5 kW (2.0 hp) on the sub. Live tools run to 8,000 rpm. The table gives no live tool power figure.
04
The listed footprint is 1,900 x 1,200 mm (74.8 x 47.2 in) and the machine weighs 1,800 kg (3,968 lb). That figure is for the machine alone; allow extra length for a bar feeder behind the headstock.
