proLine - The fourth dimension

ecoLine/proLine 400 CNC

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 TSCHUDIN proLine system additionally features a fourth CNC axis (Y-axis, Patent US 9,085,059) to move the regulating wheel vertically in order to eliminate the need to adjust the workrest blade height and to keep the grinding geometry consistent throughout the entire grinding process.

For highest demands on profile accuracy, a grinding spindle housing made from Invar to further reduce thermal influence and ultra-precise (UP) linear slides are optionally available.

Almost completely digitalized processes will facilitate a technology transfers to other manufacturing locations.

 

Simplicity as the pre-requisite 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
