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 ELDRo 100 is a rolling machine for shafts: the listed figures give a maximum shaft diameter of 100 mm and a maximum shaft length of 1,000 mm, with up to 4 simultaneous rolling heads each applying up to 30 kN. EMAG does not list it in its current lineup, so it is most likely to turn up as an older or used machine, and every figure below should be confirmed on the actual machine.
The process it is listed for is about the surface rather than the shape. The rolling heads press against the turning shaft with a closed-loop hydraulic force control, listed at ±1% accuracy, to leave a surface finish of Ra 0.1–0.4 µm and compressive stress up to 2 mm below the surface, depending on the material. Workpiece speed runs from 10–500 rpm and parts can weigh up to 30 kg.
For a buyer of a used unit the points to check follow from those rows. Rolling force and force control decide the depth of the compressive layer, so a test piece and a look at the hydraulic system say more than the nameplate. The control is listed as a Siemens SINUMERIK 840D sl, and the automation interface as EMAG standard conveyor / TrackMotion compatible, which matters if the machine is meant to join an existing EMAG line.

Strengths & Limitations
Strengths
- Up to 4 rolling heads working at the same time, each listed at up to 30 kN
- Closed-loop hydraulic force control, listed at ±1% accuracy
- Listed surface finish of Ra 0.1–0.4 µm and compressive stress up to 2 mm below the surface
- Siemens SINUMERIK 840D sl control with an EMAG conveyor / TrackMotion compatible interface
Limitations
- Not in EMAG's current lineup, so support and the listed figures need checking on the machine itself
- Shafts are limited to 100 mm in diameter, 1,000 mm in length and 30 kg in weight
- Compressive stress depth is material dependent, so the 2 mm figure is an upper limit, not a guarantee

Frequently Asked Questions
01
EMAG does not list it among its current machines. If you are looking at one, treat the listed figures (100 mm shaft diameter, 1,000 mm shaft length, up to 4 rolling heads at 30 kN each) as a starting point and confirm them on the machine.
02
It rolls the surface under controlled force. The listed results are a surface finish of Ra 0.1–0.4 µm and compressive stress reaching up to 2 mm below the surface, depending on the material. Workpiece speed runs from 10–500 rpm.
03
By a closed-loop hydraulic system, listed at ±1% accuracy, with up to 30 kN available per rolling head. On a used machine, check that the hydraulics hold the set force before relying on the listed accuracy.
04
The control is listed as a Siemens SINUMERIK 840D sl. The automation interface is listed as EMAG standard conveyor / TrackMotion compatible, so it can be linked to EMAG loading systems of that type.
