1 Position the knife at the lamellar grinding machine so that
the knife edge [1] points in the direction of rotation of the
lamellar grinding wheel [2] or the polishing wheel.
2 Align the workpieces horizontally so that they are positioned
roughly perpendicular [3] to the lamellar grinding wheel.
3 Position the knife blade [4] on the lamellar grinding wheel at
an angle of approx. 10 degrees [5].
4 When grinding, grind the sides of the workpiece alternately,
until a burr has formed over the entire area.
