Abstract
The utility model discloses a wear-resistant drill. The wear-resistant drill comprises a drill body, a titanium nitride layer is evenly arranged on the outer surface of the drill body, and the thickness of the titanium nitride layer is 5-20 nm. According to the wear-resistant drill, the titanium nitride layer is evenly arranged on the outer surface of the drill body, and titanium nitride is ultra-high in hardness and excellent in wear-resistant performance, so that the wear resistance of the drill is also greatly improved, the using loss of the drill is greatly reduced, and the using cost of an enterprise is saved.
Description
Technical field
The utility model relates to a kind of drill bit, and particularly a kind of wear-resistance bit, belongs to metal-cutting machine tool technical field.
Background technology
The cutting bit of existing metal processing mostly is steel material, because steel material very easily weares and teares when drill bit work, therefore needs often replacing, thereby makes the production work can not be continuous, affects operating efficiency, has also strengthened the cost of production of enterprise.
Utility model content
The purpose of this utility model is in order to overcome above deficiency, and a kind of wear-resistance bit is provided.
The purpose of this utility model realizes like this:
A kind of wear-resistance bit of the utility model, comprises bit body, wherein, is evenly provided with one deck titanium nitride layer on the external surface of described bit body.
As preferably, described titanium nitride layer thickness is 5-20nm.
Compared with prior art, the beneficial effects of the utility model are: because be evenly provided with one deck titanium nitride layer on the external surface of bit body, and titanium nitride has ultrahigh hardness and fabulous abrasion resistance properties, therefore make the abrasion resistance of drill bit also greatly improve, thereby greatly reduce the service wear of drill bit, saved the use cost of enterprise.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in the figure, a kind of wear-resistance bit of the utility model, comprises bit body 1, wherein, is evenly provided with one deck titanium nitride layer 2 on the external surface of described bit body 1; Described titanium nitride layer 2 thickness are 5-20nm.
A kind of wear-resistance bit of the utility model, because be evenly provided with one deck titanium nitride layer on bit body external surface, and titanium nitride has ultrahigh hardness and fabulous abrasion resistance properties, therefore make the abrasion resistance of drill bit also greatly improve, thereby greatly reduce the service wear of drill bit, saved the use cost of enterprise.
Above embodiment is only for being further described the utility model; can not be interpreted as the restriction to the utility model protection domain, some nonessential improvement that those skilled in the art makes according to foregoing of the present utility model and adjustment all belong to protection domain of the present utility model.
Claims (2)
1. a wear-resistance bit, comprises bit body, wherein, on described bit body external surface, is evenly provided with one deck titanium nitride layer.
2. a kind of wear-resistance bit according to claim 1, is characterized in that, described titanium nitride layer thickness is 5-20nm.
