ecoLine 300 / 410A

The patented 3-axes concept significantly simplifies the entire system for maximized reliability and uptime. The patented movable workrest axis (W-Axis) allows for additional grinding processes and even complex profiles can be ground.  The loading and unloading of the workpieces is always outside of the grinding zone, allowing simplified and safe automation or safe manual loading.

The ecoLine 300 CNC centerless grinder the ideal system for a high productivity of workpieces with a diameter as small as just 0.1 mm and popular for very frequent change overs or for the use with diamond grinding wheels.

The ecoLine 410 A is built as an angle head grinding machine for the simultaneous grinding of diameters AND shoulders.


The use of natural granite for the machine base and the spindle blocks,  the ecoLine machines guarantee a high process capability and maximum output. This results in  low cost per piece.


Simplicity as the prerequisite for reliability and precision.


Machine concept – less parts means more reliability

Grinding process – consistency by mastering the thermal growth



Set up process – digitally stored setting data to recall

Operation process – anyone can reproduce identical results
