CGT “CROSS GRINDING TECHNOLOGY“ KEY TO PERFECTION
At Ecograph AG we developed the unique “Cross Grinding Technology”. This technology allows to manufacture lamella & bevel edges with the finest surface finishing.
With Ecograph’s Cross Grinding Technology CGT the ground edge surface is smooth & totally “marks free”.
Grinding marks (parallel or transversal) are causing faster blade wear and originate blade cracks.
The CGT super smooth “silver like” Ecograph’s edge eliminates such marks granting the most consistent printing quality & the longest blade life.
