Abstract
A saw blade sharpening machine includes 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; and a grinding device which has a first and a second grinding head for grinding opposite tooth flanks of a saw tooth of the saw blade and an arrangement for moving the first and second grinding heads independently from one another towards and away from the saw blade plane in a direction perpendicularly thereto.
Claims16
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.
A saw blade sharpening machine 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;
- 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;
- (3) a third grinding head spaced from said first and second grinding heads and being provided with a grinding disk;
- (4) means for moving said third grinding head independently from said first and second grinding heads;
- said means for moving said third grinding head including means for moving said third grinding head in a first direction and in a second direction perpendicular to said first direction;
- said first and second directions lying in said plane.
A saw blade sharpening machine 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 including
- (1) a clamping device for receiving and clamping the saw blade;
- (2) means for rotatably supporting said clamping device;
- and
- (3) drive means for stepwise moving said clamping means for stepwise positioning the saw blade;
- 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;
- and
- (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.
