Abstract

The utility model discloses a three-blade end mill consisting of a cutter body provided with a rotary central shaft, and a cutting head at the front end of the cutter body, wherein the cutter body is provided with helical grooves; a helical convex ridge is formed among the grooves; the convex ridge is provided with an axial cutting edge formed by two curved surfaces in an intersecting way; the convex ridge can form a cylindrical surface cutting edge on the top cylindrical surface; and a certain included angle is arranged between the cylindrical surface cutting edge and the whole cylindrical surface. For the three-blade end mill adopting the structure, material scraps can be better discharged through the grooves, the cutting edges on the convex ridge can well prevent a workpiece from generating burrs, and the three-blade cutter can ensure the feeding speed of the cutting work.

Description

Three sword slotting cutters
Technical field
The utility model relates to a kind of industrial cutter, particularly a kind of milling cutter that cuts usefulness.
Background technology
Slotting cutter is a kind of shank tools, is suitable for milling end face, inclined-plane, groove and step surface.Often will carry out milling or boring to some mould or workpiece now, the material bits that milling will be stayed in the process of processing are discharged, and are convenient to further processing.In the time of cutting, be easy on the workpiece produce a lot of burrs, influence the quality of processing work.Adding man-hour, should guarantee the speed and the feed rate of processing work, will guarantee that also the burr of processing work is few as far as possible, the quality height of workpiece finished product.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of anti abrasive slotting cutter, can will cut discharge man-hour adding, and can be good at preventing producing on the workpiece burr.
For solving the problems of the technologies described above, three sword slotting cutters of the present utility model are by being made up of the cutter hub of rotary middle spindle and the cutting head of this cutter hub front end, have spiral helicine groove on the cutter hub, form spiral helicine ridge between the groove, the axial cutting edge that has two surface intersections to form on the ridge, ridge forms face of cylinder cutting edge on the nose-circle cylinder, there is certain included angle on the described face of cylinder cutting edge and the whole face of cylinder.
After adopting such structure, add the man-hour groove and can be well the material bits be discharged, the cutting edge on the ridge can be good at preventing producing on the workpiece burr, and the bite of three swords can guarantee the feed speed of cutwork.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model three sword slotting cutters.
Fig. 2 is the face of cylinder cutting edge schematic diagram of the utility model three sword slotting cutters.
The specific embodiment
Three sword slotting cutters shown in Figure 1, by forming by the cutter hub of rotary middle spindle 2 and the cutting head of this cutter hub front end, have spiral helicine groove on the cutter hub, form spiral helicine ridge 1 between the groove, have two surface intersections to form axial cutting edge 5 on the ridge 1, ridge 1 forms cutter tip on the nose-circle cylinder.Face of cylinder cutting edge 4 has certain included angle with the whole face of cylinder, can guarantee that like this front end cutting head can cut smoothly.Be connected with one section inclined-plane 3 behind the face of cylinder cutting edge 4, the material of machining bits can be slipped in the spiral helicine groove along the inclined-plane like this, have guaranteed the feed rate and the speed of slotting cutter.The spiral angle of slotting cutter is 45 °, and such angle can be good at guaranteeing the smooth work of slotting cutter.Three cutting edges are arranged on the slotting cutter face of cylinder, and three swords are the average bites that reduce each cutting edge during for rapid processing, make stable cutting, improve feed speed.
Certainly, the blade number of cutting head can also be other multiple-cutting-edge structure, and as twolip, four swords or the like, such conversion all drops within the scope of the utility model protection.
