The utility model content

The utility model is in order to solve the problems of the technologies described above, and a kind of milling cutter grinding wheel of easy to use, high-efficiency high-accuracy is provided.

The milling cutter grinding wheel that the utility model proposes, it comprises matrix, is coated on the abrasive material of matrix outer rim end face and surrounded surface.Matrix is by with the adaptive cylinder of edge of milling cutter shape and the frustum of a cone is axially superimposed constitutes.

Preferred version of the present utility model, described matrix comprises: the frustum of a cone that two small ends are relative, be located at first cylinder between two frustums of a cone, be connected in second cylinder of a frustum of a cone outer face.

More excellent, be located at the key groove of the key groove of the frustum of a cone between first cylinder and second cylinder less than another frustum of a cone.

Described matrix by can steel or aluminium make.

Described abrasive material can be metal-bonded diamond layer or resinoid bond diamond layer.

The utility model is by being provided with the frustum of a cone of two different key grooves on the emery wheel cylindrical, the frustum of a cone of little key groove can be used for grinding the back bevel angles 103 of minor diameter (φ 2～φ 5) cutter, and the frustum of a cone of big key groove is used to process the back bevel angles 103 of the cutter of major diameter (φ 6～φ 12).Thereby realize to change the cutter that emery wheel just can grind all specifications of φ 2～φ 12, improved the efficient that milling cutter grinds again, overcome frequent replacing emery wheel and influence the defective of grinding precision.

The specific embodiment

Fig. 3, Fig. 4 show the basic structure of the utility model preferred embodiment, and described milling cutter grinding wheel comprises aluminium matrix 1, is coated on the resinoid bond diamond abrasive layer 2 of this matrix outer rim end face and surrounded surface.Matrix can also be made by steel, and abrasive material 2 can adopt the metal-bonded diamond layer.As required, collective also can be made by other metal materials, as, aluminium.Abrasive material 2 can adopt other materials to make, as, metal binder cubic boron nitride layer, resinoid bond diamond layer or resin cement cubic boron nitride layer or the like.Matrix 1 is by with the adaptive cylinder of edge of milling cutter shape and two frustums of a cone are axially superimposed constitutes.Consult Fig. 5 and Fig. 6, present embodiment, matrix 1 comprise the relative frustum of a

cone

21,22 of two small ends, are located at first cylinder 20 between two frustums of a cone, are connected in second cylinder 23 of the top frustum of a cone 21 outer faces.Be positioned at the axial width D that axial width C that the key groove a of the top frustum of a cone 21 and key groove pinnacle form all forms less than the key groove b and the key groove pinnacle of the following frustum of a cone 22.As required, be positioned at the axial width D (not shown) that axial width C that the key groove a of the top frustum of a cone 21 and key groove pinnacle form also can form greater than the key groove b and the key groove pinnacle of the following frustum of a cone 22.

See also Fig. 7, the frustum of a cone of two different key grooves is set on the emery wheel cylindrical, the frustum of a cone 21 of little key groove can be used for grinding the back bevel angles 103 of minor diameter (φ 2～φ 5) milling cutter, and the frustum of a cone 22 of big key groove is used to grind back bevel angles 103, tool point angle 101, the front bevel angle 102 of major diameter (φ 6～φ 12) milling cutter.

As Fig. 6, Fig. 7, shown in Figure 8, mainly be that emery wheel is installed on the grinder during use, drive the emery wheel rotation by motor.Milling cutter is placed in milling cutter 3 positions, and milling cutter 3 and emery wheel upper surface 10 shapes are had a certain degree (grinding tool point angle 101 needed angles), utilize the tool point angle 101 of the 10 pairs of milling cutters 3 in emery wheel upper surface to grind.Milling cutter is placed in milling cutter 4 positions, and milling cutter 4 and emery wheel upper surface 10 shapes are had a certain degree (grinding front bevel angle 102 needed angles), utilize the front bevel angle 102 of the 10 pairs of milling cutters 4 in emery wheel upper surface to grind.Milling cutter is placed in the position of milling cutter 5, make milling cutter be parallel to plane of grinding wheel, and departing from the certain distance in emery wheel center (grinding the required distance in back bevel angles 103), the big key groove of the frustum of a cone 22 below utilizing is to grinding the back bevel angles 103 of major diameter cutter (φ 6～φ 12).Milling cutter is placed in the position of milling cutter 6, make milling cutter be parallel to plane of grinding wheel, and departing from the certain distance in emery wheel center (grinding the required distance in back bevel angles 103), the little wedge shape of the frustum of a cone 21 above utilizing is to grinding the back bevel angles 103 of small-diameter cutter (φ 2～φ 5).The location of above-mentioned milling cutter position can utilize the frock on the grinder to locate.
