Description
Technical Field
The utility model relates to the technical field of CBN cutters, in particular to a shockproof CBN cutter for finish turning of a brake disc surface.
Background
The CBN cutter is a cutter for artificially synthesizing superhard material with cubic boron nitride, is widely applied to cutting tools, and hard turning cutting generally refers to turning processing of quenched steel and high-temperature alloy workpiece materials, and is a process method for final processing or finish processing of materials with high hardness and high strength, so that the cutting dosage is easier to control, the chip removal amount is increased, and excircle, inner hole and end face cutting can be simultaneously carried out to finish processing of workpieces with complex shapes. The traditional cutter frequently appears in the processing and cutting process of the automobile brake disc and shakes the cutter phenomenon, and the common blade is weak in strength and poor in impact resistance, so that the service life of the cutter is easy to become low, the processed brake disc is deformed, and the processing precision of the brake disc is affected.
Disclosure of Invention
The utility model aims to provide a shockproof CBN cutter for finish turning of a brake disc surface, which can reduce vibration of the cutter in the machining and cutting process of an automobile brake disc and prolong the service life of the cutter.
In order to achieve the above purpose, the utility model is realized by the following technical scheme: the utility model provides a CBN cutter takes precautions against earthquakes for brake disc quotation finish turning, includes blade and cutter arbor, the middle part of blade is provided with the mounting hole, the front end of cutter arbor is provided with the mounting groove, the blade passes through screw and mounting hole and installs in the mounting groove, the cutter arbor sets up 7 degrees negative rake, blade knife tip department is provided with 3 degrees positive rake, the cutting angle after blade and the cutter arbor installation are accomplished is minus 4 degrees.
Specifically, each tip of the front and back sides of the blade is provided with a positive front angle of 3 degrees.
Specifically, the blade is made of CBN cubic boron nitride.
Compared with the prior art, the shockproof CBN cutter for the brake disc surface finish turning has the following beneficial effects:
this a CBN cutter takes precautions against earthquakes for brake disc quotation finish turning has 3 degrees positive rake through blade itself, and the cutting angle after the installation is accomplished is minus 4 degrees, and the blade adopts CBN cubic boron nitride material moreover, and hardness is high, can effectually reduce the cutting resistance of blade processing, has reduced the vibrations of blade and can effectively restrain the shake sword, improves the machining precision of brake disc, and in addition, every knife tip homoenergetic on positive and negative both sides of blade is used, makes the blade two-sided use, and cutting edge is many, the long service life of cutter.

FIG. 3 is an enlarged schematic view of the structure of the present utility model at A.
Wherein, 1, the blade; 2. a cutter bar; 3. a mounting groove; 4. and (5) mounting holes.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model. It should be noted that, in the description of the present utility model, terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate directions or positional relationships, which are based on the directions or positional relationships shown in the drawings, are merely for convenience of description, and do not indicate or imply that devices or elements must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present utility model. Furthermore, the terms "first," "second," "third," "fourth," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
Furthermore, it should be noted that, in the description of the present utility model, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present utility model can be understood by those skilled in the art according to the specific circumstances.
As shown in fig. 1-3, the embodiment of the utility model provides a shockproof CBN cutter for finish turning of a brake disc surface, which comprises a blade 1 and a cutter bar 2, wherein a mounting hole 4 is formed in the middle of the blade 1, a mounting groove 3 is formed in the front end of the cutter bar 2, the blade 1 is mounted in the mounting groove 3 through a screw and the mounting hole 4, a negative rake angle of 7 degrees is formed in the cutter bar 2, a positive rake angle of 3 degrees is formed at the cutter tip of the blade 1, a positive rake angle of 3 degrees is formed at each cutter tip of the front and back surfaces of the blade 1, and the cutting angle after the blade 1 and the cutter bar 2 are mounted is minus 4 degrees.
Because the material of blade 1 is CBN cubic boron nitride, make the hardness of blade 1 very high, the impact resistance of cutter is higher, make the cutter can long-time normal use, blade 1 itself has 3 degrees positive rake angles, cutter arbor 2 has 7 degrees negative rake angles, the cutting angle after blade 1 and cutter arbor 2 are installed and are accomplished is 4 degrees negative, can effectually reduce the cutting resistance of cutter processing, reduce the vibrations of cutter, can effectively restrain the phenomenon of shaking the sword, the machining precision of brake disc has been improved, 8 knife tip positions on the front and back of blade 1 all are provided with 3 degrees positive rake angles, can form 16 cutting edges on the front and back of blade 1, after the wearing and tearing of a cutting edge, can adjust blade 1 and use another cutting edge, make blade two sides homoenergetic use, the cutting edge is many, the life of cutter is long.
Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
