Service report Each service, either grinding on truck or ony laser measurement ends in a final report for the customer. Seite 28

Important information Seite 29

Wire life time Piano keying, cracks and sharp edges can destroy the wire. Optimum rounded edges prevent the wire from damages and increase the wire life time by apprximately 40 % Seite 30

The right time for regrinding? � Piano-keying > 0,1 mm � Damages with course stirps on the paper wire � Sharp edges � If the contact area between foils and the wire reaches 40 – 50 % of the whole ceramic surface. Seite 31

Regrinding intervall Influencing variables: � Speed � Amount of filler � Paper grade � Ceramic material � Type of filler � Installation position Standard values 3-4 years 2-3 years approx. 2 years 1-1,5 years Seite 32
