Overview

The EMAG ECO 200 is a compact, cost-effective conventional cylindrical grinder designed for straightforward OD, ID, and shoulder grinding operations without full CNC complexity. Unlike EMAG's production-oriented vertical machines, the ECO 200 is a traditional horizontal-spindle between-centers grinder aimed at tool rooms, prototype shops, and small-batch production environments where simplicity and quick setup matter more than automation throughput.

The machine accepts workpieces up to 100 mm in external grinding diameter with a maximum grinding length of 400 mm. The grinding headstock delivers 3.7 kW (5 hp) at 100% duty cycle with a 350 mm grinding wheel capacity and peripheral speeds up to 33 m/s. The workpiece headstock uses an MK4 socket with continuously adjustable speed up to 500 RPM, while the MK3 tailstock provides 25 mm of quill stroke for secure between-centers clamping. Maximum workpiece weight is 10 kg floating on the MK4 center or 30 kg when supported between centers.

An optional internal grinding unit with a 60 mm spindle socket and 1.5 kW drive extends the machine's capability to bore grinding, making the ECO 200 a versatile single-platform solution for cylindrical work. The machine emphasizes ease of operation and quick tooling changes — operators can be trained on it in hours rather than days, which is a meaningful advantage in job shops with varying skill levels.

The ECO 200's minimal footprint and straightforward mechanical design translate to lower acquisition and maintenance costs compared to full CNC cylindrical grinders. It competes with entry-level machines from Studer, Kellenberger, and Junker, but positions itself as the accessible option for shops that need cylindrical grinding capability without the capital commitment of a production CNC grinder. New machines typically price between $80,000 and $150,000 depending on options.

For shops already running EMAG vertical turning machines and needing a complementary grinding platform for finishing operations, the ECO 200 provides a natural fit within the EMAG ecosystem, though it operates independently without the pick-up automation integration of EMAG's vertical grinders.

Strengths & Limitations

Strengths

Simple conventional design enables rapid operator training and quick setup changes ideal for tool rooms and low-volume shops that cannot justify full CNC grinding
Compact footprint minimizes floor space requirements while delivering precision cylindrical grinding capability for OD, ID, and shoulder work
3.7 kW grinding spindle with 350 mm wheel capacity handles a wide range of cylindrical grinding tasks on workpieces up to 100 mm diameter
Optional internal grinding unit with 1.5 kW spindle adds bore grinding capability without requiring a separate machine
Between-centers capacity of 30 kg and 400 mm grinding length covers most small-to-medium shaft and pin grinding applications
Lower acquisition and maintenance costs compared to full CNC cylindrical grinders from Studer, Kellenberger, or Junker

Limitations

Non-CNC operation limits the machine to manual or semi-automatic cycles not suitable for high-volume unattended production grinding
100 mm maximum grinding diameter restricts workpiece size to small components as larger shaft or bearing work requires stepping up to the UG or HG series
3.7 kW spindle power is modest and aggressive stock removal on hardened steel or high-alloy materials will be slower than on production CNC grinders
33 m/s maximum peripheral speed precludes the use of high-speed CBN grinding wheels that require 45-80 m/s for optimal performance

Best For

Tool rooms and prototype shops needing cylindrical grinding capability without the complexity and cost of full CNC grinders Small-batch manufacturers grinding pins, shafts, bushings, and cylindrical components up to 100 mm diameter and 400 mm length Training environments where operators need to learn cylindrical grinding fundamentals on a straightforward manually-operated machine Maintenance and repair shops requiring between-centers grinding for reconditioning worn shafts and spindle components Shops already running EMAG vertical lathes that need a complementary grinding platform for finishing small cylindrical parts

Frequently Asked Questions

01 Is the EMAG ECO 200 a CNC machine?

No. The ECO 200 is a conventional (non-CNC) cylindrical grinder designed for manual and semi-automatic operation. It uses handwheels and simple controls rather than a CNC system, which makes it faster to set up and easier to operate for small batches and tool room work, but it lacks the programmability needed for automated production grinding.

02 What is the maximum workpiece size the ECO 200 can grind?

The ECO 200 grinds external diameters up to 100 mm with a maximum grinding length of 400 mm. It handles workpieces up to 10 kg floating on the MK4 headstock center, or up to 30 kg when supported between centers using both the headstock and tailstock.

03 Can the ECO 200 do internal grinding?

Yes, with the optional internal grinding unit. This adds a 60 mm spindle socket with a 1.5 kW drive, enabling bore grinding operations in addition to the standard OD and shoulder grinding capability. This makes the ECO 200 a versatile single-platform cylindrical grinder.

04 How does the ECO 200 compare to a Studer S20 or S31?

The ECO 200 is a conventional manual grinder while the Studer S20 and S31 are full CNC universal grinders with significantly more automation, axis travels, and spindle power. The ECO 200 costs roughly 30-50% less but lacks CNC programmability, automatic wheel dressing, and the production throughput of the Studer machines. Choose the ECO 200 for tool room and low-volume work; choose a Studer for production grinding.
