How much does the EMAG ECO 200 cost?
Estimated price range
Our best estimate for a cnc grinding machine in this class — not a quote from EMAG. Configuration moves it a long way.
Overview
The EMAG ECO 200 is a compact cylindrical grinding machine for shafts up to 100 mm (3.9 in) in grinding diameter and 400 mm (15.5 in) in grinding length, with a center height of 100 mm (4 in). Work is held between centers, where it may weigh up to 30 kg (66 lb), or floating, where the limit drops to 10 kg (22 lb). The workpiece headstock takes an MK4 taper and the tailstock an MK3, with a quill stroke of 25 mm (1.0 in).
The grinding wheel is 350 mm (14 in) in diameter and runs at a peripheral speed of up to 33 m/s, driven by a 3.7 kW (5 hp) spindle rated at 100% duty. That duty rating is the useful part: the stated power is available continuously, not only for short peaks. Even so, 3.7 kW (5 hp) and 33 m/s describe a conventional grinder for small parts, sized for modest stock removal rather than heavy plunge work.
The workpiece speed is continuously adjustable up to 500 RPM, and the headstock motor is listed as 0.28/0.37 kW. The table does not say what the two power figures refer to, so ask EMAG whether they mark two speed ranges or two motor versions.
Internal grinding is an option. With it fitted, the machine carries an internal grinding spindle of 60 mm (2.4 in) diameter rated at 1.5 kW (2 hp), so bores can be ground in the same setup as the outside diameter. Without it, the ECO 200 grinds outside diameters only. The G 160 and the other G machines from EMAG are gear grinders; the ECO 200 is a plain cylindrical machine and lists no module or helix figures.

Strengths & Limitations
Strengths
- Grinding spindle of 3.7 kW (5 hp) rated at 100% duty, driving a 350 mm (14 in) wheel at up to 33 m/s
- Workpieces up to 30 kg (66 lb) between centers, or 10 kg (22 lb) floating
- Workpiece speed continuously adjustable up to 500 RPM
- Optional internal grinding spindle, 60 mm (2.4 in) and 1.5 kW (2 hp), for bores in the same setup
- MK4 headstock and MK3 tailstock sockets, with a 25 mm (1.0 in) tailstock quill stroke
Limitations
- Grinding diameter stops at 100 mm (3.9 in) and length at 400 mm (15.5 in)
- Peripheral speed of 33 m/s and 3.7 kW (5 hp) of spindle power limit stock removal rates
- Internal grinding needs the optional spindle
- Floating workpieces are limited to 10 kg (22 lb)

Frequently Asked Questions
01
Up to 100 mm (3.9 in) in grinding diameter and 400 mm (15.5 in) in grinding length. Between centers the part can weigh up to 30 kg (66 lb); held floating, up to 10 kg (22 lb). The center height is 100 mm (4 in).
02
Only with the optional internal grinding unit. It adds an internal grinding spindle of 60 mm (2.4 in) diameter rated at 1.5 kW (2 hp). Without that option the machine grinds outside diameters.
03
3.7 kW (5 hp) at 100% duty, driving a 350 mm (14 in) wheel at a peripheral speed of up to 33 m/s. Because the rating is for continuous duty, that power is available for the whole grind, not just for short bursts.
04
The workpiece headstock has an MK4 socket and the tailstock an MK3 socket. The tailstock quill has a stroke of 25 mm (1.0 in), which sets how far it can retract when loading parts between centers.
05
It is continuously adjustable up to 500 RPM. The headstock drive is listed as 0.28/0.37 kW; the table does not say what the two figures stand for, so confirm with EMAG which applies to a given machine.
