Important information

SLIDE 30

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

SLIDE 31

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.
