<p>A cutter wheel for cutting fragile material and manufacturing method thereof, the cutter wheel includes a V-shape cutting blade part (1), a disc (2) and a centric shaft hole (3). The cutting blades (4) and the depressed structures (5) are distributed alternatively in the circumference of the ridge line l at the outer edge of the V-shape cutting blade part (1). Every cutting blade (4) has part of curving a1,a2, four flanks a3, a4, a5 and a6 and three V-shape cutting blades. Fixing the cutter wheel on the worktable, focusing the laser bean on the edge of the V-shape cutting blade; irradiating the edge of the blade part with the laser bean, removing the material with certain thickness to machine the depressed structures; rotating the cutter wheel with certain angle, repeating the above steps and getting the cutting blades (4) and depressed structures (5) which are distributed alternatively in the circumference of the ridge line at the edge of the cutting blade part.</p> |
