A novel cutting edge cutter is a hard alloy milling cutter. The novel cutting edge cutter of this embodiment includes cutter arbor 1 and tool bit 2, and tool bit 2 is connected in 1 one end of cutter arbor. The machined tool bit 2 comprises a front tool face, a rear tool face and a cutting edge. The back knife face is connected with the front knife face, and the cutting edge is formed between the front knife face and the back knife face. In order to ensure that the surface of a workpiece processed by the cutter reaches certain cleanliness and different roughness and improve the mechanical property of the surface of the workpiece, thereby improving the fatigue resistance, the adhesion strength and the prolonged durability of a metal workpiece, being beneficial to metal leveling and the like, a sand blasting surface 3 formed by sand blasting is arranged on the rear cutter surface. Specifically, the surface of the rear cutter face, which is opposite to the plane to be cut of the workpiece, is provided with a sand blasting surface 3 formed by sand blasting. Referring to fig. 1, preferably, when the new cutting edge tool is machined from a raw material, the portion of the new cutting edge tool where the cutting edge 2 is located is subjected to sand blasting and then further machined to form the flank face. After the surface of the raw material is subjected to sand blasting, the machined tool blade is the reserved material surface, the blade surface is contacted with the machined material in the cutting process, and the surface smoothness of the workpiece and the service life of the tool are greatly improved due to the fact that the material subjected to sand blasting is good in surface smoothness and high in strength. The sand blasting depth of the sand blasting surface 3 needs to be controlled between 0.002mm and 0.005 mm.

The sand blasting process adopts special sand blasting equipment, adopts compressed air as power, and carries out high-speed beam spraying on abrasive materials such as iron sand, ceramic sand, pickaxe sand and the like to be sprayed on the surface of a workpiece for processing. The surface treatment of the workpiece is changed to a certain extent. In different embodiments, the blasting material for blasting may be quartz sand, silicon carbide sand, etc., and the blasting depth of the blasting surface 3 is 0.002mm, 0.004mm, 0.005mm, etc.

In order to improve the use effect of the tool after sand blasting, in one embodiment, the area of the sand blasting surface 3 at least occupies 3/4 of the surface area of the flank face which is to be a surface to be cut and is an effective contact part for workpiece processing.

In one embodiment, the blasting depth of the blasting surface 3 is 0.004mm-0.005 mm. Preferably, the blasting depth of the blasting surface 3 is 0.005 mm.

In one embodiment, the entire outer surface of the flank face is the blasted surface 3, ensuring that the non-blasted surface 3 on the tool does not contact the workpiece to be machined. If the outer surface of the flank face after the raw material processing by the primary blasting is not entirely the blasted face 3, the secondary blasting process may be performed so that the entire outer surface of the flank face is the blasted face 3. Preferably, the outer surfaces of both the rake face and the flank face are the blasted surfaces 3.
