Machine Comparison
Haas CL-1 vs Haas SB-28
Haas Automation vs Haas Automation · CNC Lathes
Summary
The Haas CL-1 and Haas SB-28 are both Haas lathes running the Haas Next Generation Control, but they do very different work. The CL-1 is a compact chucker for small parts, with a 5C collet nose, 1 in (25 mm) bar capacity and a 4.95 in (126 mm) turning diameter. The SB-28 is a heavy production lathe with an A2-8 nose, 2.9 in (74 mm) bar and 13.5 in (345 mm) turning diameter.
The SB-28 has 40 hp (29.8 kW) against 5 hp (3.7 kW), 23.2 in (590 mm) of Z travel against 8 in (203 mm), and 12 stations against 8. The CL-1 spins to 6,000 rpm against 3,200 rpm, rapids at 757 ipm against 630 ipm, and lists at US$54,995 against US$94,995.

Advantages
Haas CL-1
- 6,000 rpm spindle against 3,200 rpm for small diameters
- 757 ipm (19.2 m/min) rapids against 630 ipm (16 m/min)
- 12 in (305 mm) X travel against 9 in (230 mm)
- Lower list price, US$54,995 against US$94,995
Haas SB-28
- 40 hp (29.8 kW) spindle against 5 hp (3.7 kW)
- 13.5 in (345 mm) turning diameter and 2.9 in (74 mm) bar against 4.95 in (126 mm) and 1 in (25 mm)
- 23.2 in (590 mm) Z travel against 8 in (203 mm)
- 12 stations against an 8-station turret
Verdict
These lathes serve different jobs. The Haas CL-1 is for high-volume small parts under 1 in of bar, such as dental screws, fasteners and electronic fittings, where 6,000 rpm and a low list price matter. The Haas SB-28 is for stainless, titanium and alloy steel parts up to 13.5 in in diameter, such as valve components and flanges, that need 40 hp and 23.2 in of Z travel.
