Rapid cutting type double-edged milling cutter

Abstract

The invention discloses a rapid cutting type double-edged milling cutter. The cutter comprises a cutter cylinder, a butt-joint column, clamping grooves, a butt-joint port, a connecting ring, a cutterbody, a fixing groove, a first fastening hole, a second fastening hole, a connecting hole, a chip discharging groove and a cutting blade. The rapid cutting type double-edged milling cutter has the beneficial effects that the six clamping grooves are formed with the butt-joint port as the center in an inwards concave mode, an angle formed between each clamping groove and the butt-joint port is 60 degrees, and incompact clamping during connecting between the clamping grooves and an external motor is avoided; the cutter body is formed by staggering two pieces, an included angle formed between thetwo pieces is 90 degrees, the chip discharging groove is formed in the back face of the fixing groove in a sagittal symmetry mode, and the cutting sharpness of the milling cutter is guaranteed; and the cutting blade is fixedly arranged in the fixing groove and fixed through the first fastening hole and the second fastening hole in a front-back direction, the cutting blade is in fastened connection with the interior of the fixing groove in a completely concave mode, and the situation that a protruding cutting blade is prone to being damaged is avoided.

Description

technical field [0001] The invention relates to a double-edged milling cutter, in particular to a fast-cutting double-edged milling cutter, which belongs to the technical field of milling cutters. Background technique [0002] Milling cutter is a rotating tool with one or more teeth for milling. When working, each tooth cuts off the allowance of the workpiece intermittently. Milling cutters are mainly used for machining planes, steps, and grooves on milling machines. When optimizing the milling effect, the blade of the milling cutter is another important factor. In any milling, it is an advantage if more than one blade participates in cutting at the same time, but the number of blades participating in cutting at the same time Too much is a disadvantage. It is impossible for each cutting edge to cut at the same time during cutting. The required power is related to the number of cutting edges involved in cutting. In terms of chip formation process, cutting edge load and proces...

AI Technical Summary

Problems solved by technology

[0003] Therefore, a fast-cutting double-edged milling cutter is needed to meet the current market demand. The common faults, one, the hardness of the cutter cylinder of existing fast-cutting double-edged milling cutter is not enough, causes the service life of this fast-cutting double-edged milling cutter not long, its two, existing fast-cutting double-edged milling cutter The top of the knife is not equipped with a card slot, which causes the buckle not to be tight when connected to an external motor. Third, the depth of the groove at the bottom of the existing fast-cutting double-edged milling cutter is not enough, resulting in a convex shape of the blade, which is easily damaged
