Description
Technical field
The utility model relates to cutting-tool engineering field, specifically a kind of CBN cutter.
Background technique
Cutter be machining must be with tool, the main cutting of cutter is the side edge on cylindrical surface, the cutting on end face
Sword is end cutting edge, is mainly used to process groove, step, small plane and various mutually perpendicular planes, due to the material of cutter
Material is kept cutter hardness poor, is prone to wear and damages without being made of optimal material.
Utility model content
The purpose of this utility model is to provide a kind of CBN cutters, to solve the problems of the prior art.
To achieve the above object, the utility model provides the following technical solutions: a kind of CBN cutter, including cutter body, institute
It states cutter body to be composed of knife handle, the frustum of a cone and cutter head, the frustum of a cone is provided on described knife handle one end, the frustum of a cone
The vertical center line of vertical center line and knife handle coincides, and the frustum of a cone other end is provided with cutter head, the cutter head it is vertical
The vertical center line of center line and the frustum of a cone coincides, and the cutter head is composed of end sword, chip space and side tool sword, the knife
First end is provided with blade, and cutter head outer wall two sides are provided with side tool sword, and side tool sword on cutter head in the shape of a spiral, it is described
Spiralization chip space between sides adjacent blade.
Preferably, described cutter body one end is provided with chamfering b.
Preferably, the angle a being arranged between the frustum of a cone and knife handle is 20 °.
Preferably, the cutter head is made of CBN material.
Compared with prior art, the utility model has the beneficial effects that using CBN material by the cutter head on cutter body
It is made, the thermal stability under the hardness with higher of cutter head made of CBN material, chemical inertness and high temperature makes the end on cutter head
Sword and side tool sword are sharper when processing to material, and the service life is longer for cutter head, in the lower high temperature pair that works long hours
The damage of cutter head becomes very low.The utility model has novel design by a series of setting of structures, and structure is simple, high hard
Degree and the good advantage of wearability.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of CBN cutter of the utility model.
Fig. 2 is enlarged structure schematic diagram at the A of the utility model.
Fig. 3 is the structural schematic diagram at another visual angle of the utility model.
In figure: 1, the frustum of a cone；2, knife handle；3, cutter body；4, sword is held；5, cutter head；6, chip space；7, side tool sword.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Please refer to Fig. 1~3, in the utility model embodiment, a kind of CBN cutter, including cutter body 3, cutter body 3 by
Knife handle 2, the frustum of a cone 1 and cutter head 5 are composed, and the frustum of a cone 1, the vertical center line and knife of the frustum of a cone 1 are provided on 2 one end of knife handle
The vertical center line of handle 2 coincides, and the angle a being arranged between the frustum of a cone 1 and knife handle 2 is 20 °, and 1 other end of the frustum of a cone is provided with
Cutter head 5, cutter head 5 are made of CBN material, and the vertical center line of the vertical center line and the frustum of a cone 1 of cutter head 5 coincides, cutter head 5
It is composed of end sword 4, chip space 6 and side tool sword 7,5 one end of cutter head is provided with blade, and 5 outer wall two sides of cutter head are provided with side
Blade 7, and side tool sword 7 on cutter head 5 in the shape of a spiral, spiralization chip space 6 between sides adjacent blade 7,3 one end of cutter body
It is provided with chamfering b, is made up of the cutter head 5 on cutter body 3 of CBN material, cutter head 5 made of CBN material has higher
Hardness, the thermal stability under chemical inertness and high temperature, make end sword 4 on cutter head 5 and side tool sword 7 when processing to material
Sharper, the service life is longer for cutter head 5, becomes very low to the damage of cutter head 5 working long hours lower high temperature.
The working principle of the utility model is: being made up of the cutter head 5 on cutter body 3 of CBN material, CBN material
Thermal stability under manufactured cutter head 5 hardness with higher, chemical inertness and high temperature makes end sword 4 and side tool sword on cutter head 5
7 is sharper when processing to material, and the service life is longer for cutter head 5, in damage of the lower high temperature to cutter head 5 that work long hours
It is bad to become very low.
It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and
And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this is practical new in other specific forms
Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this is practical new
