Abstract:
A saw blade sharpening machine for sharpening a circular saw blade; comprising(a) a receiving and positioning chuck assembly for setting a saw blade in a grinding position in a plane corresponding to a main saw blade plane; said chuck assembly defining a radial direction and a circumferential direction of the saw blade when installed in said chuck assembly; and(b) a grinding device including(1) a first and a second grinding head for grinding opposite tooth flanks of a saw tooth of said saw blade;(2) means for moving said first and second grinding heads independently from one another towards and away from said plane in a direction perpendicularly thereto; said means for moving said first and second grinding heads perpendicularly to said plane comprising(i) a first means for moving said first grinding head along a first linear path Y2.1; and(ii) a second means for moving said second grinding head along a second linear path Y2.2;(3) a third means for moving said first and second grinding heads along a third linear path Z2 parallel to said plane and parallel to said radial direction; and(4) a fourth means for moving said first and second grinding heads along a fourth linear path X2 parallel to said plane and tangentially to said circumferential direction.
