Abstract
The invention discloses a CBN blade with a chip breaker groove. A blade body is a 80-degree rhombus cylinder and comprises an upper end surface, a lower end surface, a support surface and a clamp hole, wherein the upper end surface is parallel to the lower end surface; cutting edges are arranged at the end parts of the long axes of the upper and lower end surfaces; and a chip breaker groove is formed at the point of the blade, wherein the angle between the chip breaker groove and the side edge of the blade is 15-25 degrees, the distance is 0.2-0.3mm, the distance from the upper tool face is 0.2-0.3mm, and the angle is 30 degrees. According to the invention, since the special chip breaker groove is formed on the blade to perform forced chip breaking of chips, bird nest-shaped chips can be completely controlled in the case of a hard vehicle, and the phenomenon that the chips are wound on the blade, a cutter bar, a workpiece and the like is avoided.
Description
Technical field
The present invention relates to a kind of machining tool, relate in particular to a kind of CBN blade with chip-breaker.
Background technology
In the continuous turning of existing hardened steel, because being cut properties of materials, elongated smear metal can appear in the processing, because effectively chip breaking, the smear metal meeting presents nest like, is wrapped on blade, knife bar and the workpiece, cause that surface of the work scratches, cause surface roughness poor, even can break the point of a knife cutting edge, the damage cutter.
Summary of the invention
The present invention has overcome shortcoming of the prior art, and a kind of CBN blade with chip-breaker is provided.
In order to solve the technical problem of above-mentioned existence, the present invention is achieved by the following technical solutions:
A kind of CBN blade with chip-breaker, blade body is 80o rhombus cylinder, comprise upper surface, lower surface, supporting surface and clamping hole, parallel lower surface, upper surface, major axis end in the upper and lower end face is provided with cutting edge, make at blade point of a knife position with blade side edge angle and become 15-25 degree, distance to be the 0.2-0.3 millimeter, knife face 0.2-0.3 millimeter on the distance, angle is 30 chip-breakers of spending.
Owing to adopt technique scheme, a kind of CBN blade with chip-breaker provided by the invention, its beneficial effect is: owing to make special-purpose chip breaking grooved at blade, forced chip-cutting is carried out in smear metal, therefore the nest like smear metal that occurs in the time of can controlling hard car fully avoids smear metal to be wrapped in the generation of blade, knife bar and the first-class situation of workpiece.

Fig. 2 is the side view of a kind of CBN blade with chip-breaker of the present invention;
Fig. 3 is embodiment of the invention schematic diagram;
Fig. 4 is embodiment of the invention schematic side view.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment the present invention is described in further detail:
A kind of CBN blade with chip-breaker, such as Fig. 1, shown in 2, blade body 2 is 80o rhombus cylinder, 12.7 millimeters of inscribed circle sizes, adopt DCC500 (e6) material, it comprises the upper surface, the lower surface, supporting surface and clamping hole, parallel lower surface, upper surface, the thickness of blade is 4.76 ± 0.025 millimeters, major axis end in the upper and lower end face is provided with cutting edge 1, and cutting edge 1 is welded on blade body 2 for the K10 material adopts the method for welding, makes with blade side edge angle at blade point of a knife position becoming the 15-25 degree, distance is the 0.2-0.3 millimeter, knife face 0.2-0.3 millimeter on the distance, angle are the chip-breaker of 30 degree.
