Abstract

The utility model discloses a shock absorption margin end mill, which comprises an end mill (1). A front corner (2) and a rear corner (3) are arranged at the cutting edge of the end mill (1). The end mill is characterized in that a shock absorption margin inclined face (4) is arranged at a position from the edge of the cutting edge to the rear corner (3) of the end mill (1), the width (b) of the shock absorption margin inclined face (4) ranges from 0.01 millimeter to 0.15 millimeter, and an included angle (alpha) between the shock absorption margin inclined face (4) and a cutting planar face (5) of the cutting edge of the end mill (1) ranges from 1 degree to 4.5 degrees. The shock absorption margin end mill not only can effectively increase strength of the end mill cutting edge and processing fineness, but also has the advantages of simple technical process, lower manufacturing cost and longer service life.

Description

A kind of damping land slotting cutter

Technical field

The utility model relates to a kind of damping land slotting cutter, belongs to the slotting cutter manufacture technology field.

Background technology

At present, the shape of its cutting edge is mainly determined by anterior angle and relief angle on traditional vertical milling cutter, after the anterior angle of slotting cutter cutting edge and relief angle are determined, under the situation of same material and identical processing technology, the intensity of the cutting edge of this slotting cutter has also just been determined, in order to strengthen the slotting cutter edge strength, the mode that often adopts cutting edge to slotting cutter to carry out Passivation Treatment in the prior art realizes, though this mode can improve the cutting edge certain intensity, but exist the processing technology complexity, unmanageable shortcoming, and adopt the numerical control machine for inactivating to make, then exist the higher shortcoming of cost again, and the slotting cutter through passivation is adding man-hour, also occurs reducing the piece surface fineness that slotting cutter processes easily.Therefore, existing slotting cutter manufacturing technology still is not ideal enough.

Summary of the invention

The purpose of this utility model is, provides that a kind of processing technology is simple, cost of manufacture is lower and can effectively improve the slotting cutter edge strength and the damping land slotting cutter of processing fineness, to overcome the deficiencies in the prior art.

The technical solution of the utility model: a kind of damping land slotting cutter of the present utility model is, this damping land slotting cutter is to improve to form on the basis of existing slotting cutter, it comprises existing slotting cutter planform, promptly be provided with anterior angle and relief angle at the cutting edge place of existing slotting cutter, it is characterized in that: on the cutting edge limit of the cutting edge of slotting cutter to also being provided with a damping land inclined-plane between the relief angle, and the width on damping land inclined-plane is 0.01～0.15 millimeter, and the angle of the cutting plane of damping land inclined-plane and slotting cutter is 1 °～4.5 °.

The angle of the relief angle of above-mentioned slotting cutter is greater than 10 °～20 ° of the angles on damping land inclined-plane.

Owing to adopted technique scheme, the utility model has increased a damping land inclined-plane on the back angular position of the cutting edge of existing slotting cutter, the angle of the cutting plane of this damping land inclined-plane and slotting cutter cutting edge is significantly smaller than the relief angle of conventional slotting cutter, and the width on this damping land inclined-plane is controlled at 0.01～0.15 millimeter, and then produce the bigger cutting edge relief angle of angle, slotting cutter after improving like this, through evidence, the intensity of its cutting edge will be higher than 2～3 times of conventional end mill, and the piece surface fineness that processes is than highly polished 1～3 the fineness grade of piece surface that processes under identical machined parameters with the slotting cutter after the change.Therefore, the utility model compared with prior art, the utility model not only has the advantage that can effectively improve slotting cutter edge strength and processing fineness, but also has the advantage that processing technology is simple, cost of manufacture is lower, service life is long.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Embodiment of the present utility model: when making the utility model, used slotting cutter material and manufacture craft are all same as the prior art, but when making relief angle, on the position of the relief angle 3 of the cutting edge of slotting cutter 1, produce a damping land inclined-plane 4 earlier, and the width b on damping land inclined-plane 4 is controlled at 0.01～0.15 millimeter scope, damping land inclined-plane 4 and the angle α of the cutting plane 5 of slotting cutter 1 cutting edge are controlled at 1 °～4.5 ° scope; After damping land inclined-plane 4 is completed, produce the relief angle 3 of the cutting edge of slotting cutter 1 again.

Concrete when making damping land slotting cutter of the present utility model, it comprises the structure of the slotting cutter 1 of existing structure, promptly all be provided with anterior angle 2 and relief angle 3 at the cutting edge place of slotting cutter 1, the preparation method of its anterior angle 2 can directly adopt the method for prior art to make, when making relief angle, earlier on the cutting edge limit of the cutting edge of slotting cutter 1 to producing a damping land inclined-plane 4 between the relief angle 3 that will make, and the width b on damping land inclined-plane 4 is controlled at 0.01～0.15 millimeter, damping land inclined-plane 4 and the angle α of the cutting plane 5 of slotting cutter 1 cutting edge be controlled at 1 °～4.5 ° scope, and then produce the relief angle 3 of slotting cutter 1 and other traditional structure division of slotting cutter 1 by conventional method, and be controlled at the angle of relief angle 3 greater than the scope of 10 °～20 ° of the angle α number of degrees on damping land inclined-plane 4.
