Haas EC-500 Horizontal Machining Center vs Haas EC-500/50
Haas Automation vs Haas Automation · Horizontal Machining Centers
Summary
The Haas EC-500 and EC-500/50 share the same frame: 32 in (813 mm) of X, 25 in (635 mm) of Y and 28 in (711 mm) of Z travel on 19.69 × 19.69 in (500 × 500 mm) pallets, with 30 hp (22.4 kW) at the spindle. The difference is the taper: 40 on the EC-500, 50 on the EC-500/50.
The EC-500/50 trades speed for cutting force. It delivers 340 ft-lbf @ 700 rpm of torque against 90 ft-lbf @ 2,000 rpm and carries 50+1 tools against 30+1. The EC-500 spins to 8,100 rpm against 7,500 rpm, changes tools in 2.8 s against 4.2 s, cuts chip-to-chip time to 3.6 s from 6.3 s and rapids at 1,400 ipm (35.6 m/min) against 710 ipm (18 m/min). Haas lists them at US$310,995 and US$349,995.

Advantages
Haas EC-500 Horizontal Machining Center
- 2.8 s tool change and 3.6 s chip-to-chip against 4.2 s and 6.3 s
- 1,400 ipm (35.6 m/min) rapids against 710 ipm (18 m/min)
- 8,100 rpm spindle against 7,500 rpm
- Lower published list price, US$310,995 against US$349,995
Haas EC-500/50
- 340 ft-lbf @ 700 rpm (460 N·m) of torque against 90 ft-lbf @ 2,000 rpm
- CT or BT 50 taper for heavy roughing
- 50+1 tools against 30+1
Verdict
Pick by material. The EC-500 suits medium-volume prismatic parts in aluminum and lighter steel cuts, where 1,400 ipm rapids and 3.6 s chip-to-chip time shorten every cycle. The EC-500/50 suits shops roughing steel and cast iron on tombstones, where 340 ft-lbf of low-speed torque, a 50 taper and 50+1 tools matter more than the faster non-cutting time.
