The utility model aims to solve the technical problem that to above-mentioned defect, provide a tungsten steel coating end mill, hardness is high, difficult wearing and tearing fracture, production efficiency is high.
The utility model provides a technical scheme that its technical problem adopted as follows:
the tungsten steel coating end milling cutter comprises a cutter handle and a cutting edge, wherein tungsten steel coatings are coated on the surfaces of the cutter handle and the cutting edge, one end of the cutter handle is connected with the cutting edge through a reducing section, and the other end of the cutter handle is provided with a chamfer; the cutting edge is provided with a spiral groove, and one end of the groove extends to the end part of the cutting edge; the surface of the variable diameter section is a sunken arc surface, and the radius of the arc surface is 12 +/-1 mm.
Further, the length of the knife handle is 50 +/-1 mm.
Further, the length of the blade is 6-6.5 mm.
Further, the length of the groove is 5.5-6 mm.
Further, the diameter of the knife handle is 4-4.01 mm.
Further, the diameter of the cutting edge is 3.18-3.2 mm.
The utility model has the advantages that:
(1) the utility model discloses a tungsten steel coating can improve end mill's hardness, makes it be difficult to by wearing and tearing so that the fracture, and the convex design is adopted on the surface of reducing section moreover, can improve end mill's structural strength, and the chip removal of being convenient for in the design of slot.
