Abstract

The utility model discloses a MCD concave circular arc milling cutter, including the cutter body, the cutter body front end is equipped with blade body, the last spill circular arc cutting edge of having seted up of blade body, the circular arc cutting edge is tangent with the straight line on 0 and 90 positions, set up 15 butterfly angle on the circular arc cutting edge, there is a chamfer of one 45 butterfly angle straight line and all swords crossing positions, still set up 15 - 25 radial relief angle and 15 - 20 axial relief on the circular arc cutting edge, radial relief angle is 0.08 -0.1mm. In this way, the utility model discloses can be the very good surface quality who becomes concave circular arc milling cutter processing 3D face and obtain with the MCD material, processing concave circular arc sector can arrive 90 degrees to can the mass production.

Description

MCD concave arc milling cutter

Technical field

The utility model relates to milling cutter field, particularly relates to a kind of MCD concave arc milling cutter.

Background technology

Along with the appearance of modern integrated technology, machined, to high accuracy future development, has proposed quite high requirement to cutting performance. Because golden MCD coefficient of friction is little, thermal coefficient of expansion is low, thermal conductivity is high, can cut smear metal as thin as a wafer, smear metal is easily flowed out, little with the affinity of other material, is difficult for producing built-up edge, caloric value is little, thermal conductivity is high, can avoid the impact of heat on blade and workpiece, and therefore blade is difficult for passivation, cutting deformation is little, can obtain the surface of better quality. We utilize genus characteristic that MCD material is become to the extraordinary surface quality that concave arc milling cutter processing 3D face obtains.

Utility model content

The technical problem that the utility model mainly solves is to provide a kind of MCD concave arc milling cutter, can directly process 3D face with MCD concave arc milling cutter, and synchronously improves 3-4 working (machining) efficiency doubly.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of MCD concave arc milling cutter is provided, comprise cutter hub, described cutter hub front end is provided with blade bodies, in described blade bodies, offer a concave circular arcs blade, described Roound edge 0 ° with 90 ° of positions on tangent with straight line, on described Roound edge, offer the butterfly angle of one 5 °, there is the chamfering of 45 ° the straight line position crossing with all swords, butterfly angle, on described Roound edge, also offer the radial clearance angle of 15 °-25 ° and the axial relief angle of 15 °-20 °, radial clearance angle is 0.08-0.1mm.

In preferred embodiment of the utility model, described Roound edge is 1/4 circular arc of radius R 1.4mm.

The beneficial effects of the utility model are: the utility model has solved MCD monocrystalline cutter in the past cannot volume production process the recessed sector circular arc that is greater than 60 degree, use the method can process concave arc sector to 90 degree, and can mass production, the affinity of cutter and other material is little, is difficult for producing built-up edge, caloric value is little, thermal conductivity is high, can avoid the impact of heat on blade and workpiece, and therefore blade is difficult for passivation, cutting deformation is little, can obtain the surface of better quality.

Fig. 2 be shown in blade bodies moulding place amplify the structural representation of a preferred embodiment;

In accompanying drawing, the mark of each parts is as follows: 1, cutter hub; 2, blade bodies; 3, Roound edge.

Detailed description of the invention

To the technical scheme in the utility model embodiment be clearly and completely described below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiment. Based on the embodiment in the utility model, those of ordinary skill in the art are not making all other embodiment that obtain under creative work prerequisite, all belong to the scope of the utility model protection.

Refer to Fig. 1, the utility model embodiment comprises:

A kind of MCD concave arc milling cutter, comprise cutter hub 1, described cutter hub 1 front end is provided with blade bodies 2, in described blade bodies 2, offer a concave circular arcs blade 3, described Roound edge 30 ° with 90 ° of positions on tangent with straight line, on described Roound edge 3, offer the butterfly angle of one 5 °, there is the chamfering of 45 ° the straight line position crossing with all swords, butterfly angle, on described Roound edge 3, also offer the radial clearance angle of 15 °-25 ° and the axial relief angle of 15 °-20 °, radial clearance angle is 0.08-0.1mm.

In addition, 1/4 concave arc that described Roound edge 3 is radius R 1.4mm.

Operation principle of the present utility model is for to be provided with blade bodies 2 at cutter hub 1 front end, in blade bodies 2, offer a concave circular arcs blade 3, Roound edge 3 is 1/4 concave arc of radius R 1.4mm, Roound edge 30 ° with 90 ° of positions on tangent with straight line, on Roound edge 3, offer the butterfly angle of one 5 °, there is the chamfering of 45 ° the straight line position crossing with all swords, butterfly angle, on Roound edge 3, also offer the radial clearance angle of 15 °-25 ° and the axial relief angle of 15 °-20 °, radial clearance angle is 0.08-0.1mm, use Britain COBORNPG3B equipment cylinder iron to coil monocrystalline is ground, our technique is revised the external arc that is less than altogether R1.4 on cast iron plate, can be between R1.0-1.2, by add diamond paste on cast iron plate, under the condition of on-line velocity 70-100m/min, realize cast iron plate minimal wear and grind round tool in MCD monocrystalline.

The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
