Blade Grinding
Blades, fitted on the chipping wheel, are double-sided, i.e. reversible if one side is
blunt.
Blades edge regrinding requires high demands for keeping cutting edge shape.
While grinding it is necessary to keep its optimal geometry, see following figure.
Proper shapes prolong blade service life.
While regrinding it is necessary to keep the same weight of particular
blades because of balance of their rotating mass. For grinding use
always a grinder with its magnetic table and a special jig.
Detailed geometry of blade edge
Grind every blade only up to minimum distance from edge to its fixing
bolt. i.e. 37,5 mm. This distance on a new blade is 100 mm, see
following figure.
