Edge Finishing & Profiles
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.
• Longer service life
• Less waste
• Less problems
• Lower costs
The dynamic zone
Sharp edges in the dynamic zone causes the breakage of the doctor blade.
Doctor blades with longitudinal grinding pattern are exposed to break where the longitudinal streaks overlap with the crystalline lines of fracture.
Unlapped doctor blades negatively influence the function during the start-up of printing job (waste of printing substrate).
The dynamic zone
The lamella parallel zone endsin a smooth radius to the full thickness base material.
The fine cross grinding pattern of ECOGRAPH Doctor Blades results into the best possible surface quality of the lamella.
ECOGRAPH Doctor Blades have lapped lamella tips. With the use of especially fine lapped edge the doctor blade wipes the cylinder 100% clean from the first meters of each printing job.
