Haas Mini Mill vs Haas Super Mini Mill
Haas Automation vs Haas Automation · Vertical Machining Centers (VMC)
Summary
The Haas Super Mini Mill is the faster version of the Haas Mini Mill. Both have the same 16 x 14 x 15 in (406 x 356 x 381 mm) travels, the same 36 × 12 in table, a 500 lb (227 kg) load limit and a 40-taper spindle. What the step up buys is speed and tool capacity.
The Haas Super Mini Mill runs to 10,000 rpm against 8,000 rpm with 15 hp (11.2 kW) against 10 hp (7.5 kW), carries 30+1 tools against 10 or 20, changes tools in 2.8 s against 4.2 s and rapids at 1,200 ipm (30.5 m/min) against 800 ipm (20.3 m/min). The Haas Mini Mill has the higher torque figure, 45 ft-lbf @ 500 rpm against 22 ft-lbf @ 5,000 rpm. Haas lists the Mini Mill at US$47,995 and the Super Mini Mill at US$55,995.

Advantages
Haas Mini Mill
- Higher spindle torque at low speed: 45 ft-lbf @ 500 rpm against 22 ft-lbf @ 5,000 rpm
- Lower published list price, US$47,995 against US$55,995
Haas Super Mini Mill
- 10,000 rpm spindle against 8,000 rpm, with 15 hp (11.2 kW) against 10 hp (7.5 kW)
- 30+1 tools against 10 or 20
- 2.8 s tool-to-tool and 4.2 s chip-to-chip against 4.2 s and 5 s
- 1,200 ipm (30.5 m/min) rapids against 800 ipm (20.3 m/min)
Verdict
Buy the Haas Super Mini Mill for short-run production of small aluminum parts, where 10,000 rpm, 30+1 tools and 1,200 ipm (30.5 m/min) rapids pay back the higher list price, US$55,995 against US$47,995. Buy the Haas Mini Mill for prototype, toolroom, training and second-operation work, where cycle time matters less, and for cuts with larger tools at low speed that use its 45 ft-lbf at 500 rpm.
