DN Solutions LYNX 2100 LSYB vs Haas ST-20Y
DN Solutions vs Haas Automation · CNC Lathes / Turning Centers
Summary
The DN Solutions LYNX 2100 LSYB and the Haas ST-20Y are Y-axis turning centers of the same size: about 300 mm (12 in) of turning diameter, an 8 in class chuck, 12 tool stations and a 15 kW (20 hp) class spindle. They differ in how the spindle and the live tools are geared.
The DN Solutions machine is the faster one: 4,500 rpm at the main spindle against 4,000 rpm, and 6,000 rpm live tools against 4,000 rpm. The Haas has more torque for roughing, 150 ft-lbf @ 500 rpm (203 N·m @ 500 rpm) against 169 N·m (125 ft-lb), and takes longer parts, with a 22.5 in (572 mm) turning length against 510 mm (20 in). Y travel is near equal at 105 mm (4 in) against ± 2 in (± 51 mm).

Advantages
DN Solutions LYNX 2100 LSYB
- 6,000 rpm live tools against 4,000 rpm
- 4,500 rpm main spindle against 4,000 rpm
- Lighter machine: 4,200 kg (9,259 lb) against 10,480 lb (4,754 kg)
Haas ST-20Y
- 150 ft-lbf @ 500 rpm (203 N·m @ 500 rpm) of spindle torque against 169 N·m (125 ft-lb)
- 22.5 in (572 mm) turning length against 510 mm (20 in)
Verdict
Choose the DN Solutions LYNX 2100 LSYB for parts with a lot of milling, drilling and tapping with small tools, where 6,000 rpm live tools and a 4,500 rpm spindle shorten the cycle. Choose the Haas ST-20Y for steel parts that are roughed hard or run longer than 510 mm (20 in): it has 150 ft-lbf @ 500 rpm at the spindle and 22.5 in (572 mm) of turning length. Size and tool count do not separate them.
