Haas Automation vs Haas Automation · CNC Lathes
Summary
The Haas ST-10Y is the ST-10 compact lathe with Y-axis milling added. Both have 7.88 in (200 mm) of X and 16 in (406 mm) of Z travel, 16 in (406 mm) of turning length, 1.75 in (44 mm) bar capacity, a 6.5 in (165 mm) chuck and the same 6,000 rpm, 15 hp (11.2 kW) A2-5 spindle with 75 ft-lbf @ 1,300 rpm. Both list a 6,000 rpm sub-spindle and weigh 7,900 lb.
The ST-10 swings slightly more, 12 in (305 mm) against 11 in (279 mm), and its listed rapids are 1,200 ipm (30.5 m/min) against 472 ipm (12 m/min). The ST-10Y adds off-center milling for cross-holes, flats and keyways. Haas lists the ST-10 at US$64,995 and the ST-10Y at US$102,995.

Advantages
Haas ST-10
- Lower published list price, US$64,995 against US$102,995
- 1,200 ipm (30.5 m/min) rapids against 472 ipm (12 m/min)
- 12 in (305 mm) max turning diameter against 11 in (279 mm)
Haas ST-10Y Turning Center
- Y-axis for off-center cross-holes, flats and keyways in one setup
- Completes milled features that would otherwise need a second-op VMC
Verdict
Buy the ST-10Y only if your small bar parts carry off-center features such as cross-holes, flats or keyways that now go to a mill; done-in-one machining is what the extra cost buys. For plain ID/OD turning and threading of small-diameter bar, the ST-10 does the same work on the same spindle with faster listed rapids and a US$64,995 list price.
