Abstract

The utility model belongs to the technical field of machining, and provides a center with a super-hard coating. The center with the super-hard coating comprises a center body and hard alloy inlaid at the top end of the center. The top end of the hard alloy is of a cone shape, is coated with a TiC or TiN coating through chemical vapor deposition (CVD), the service life can be greatly prolonged, coating repair can be carried out again after use abrasion, and repeated utilization can be achieved. According to the center with the super-hard coating, due to the fact that the TiC or the TiN coating is coated, abrasive resistance of the center is improved, cost can be reduced, and repeated repair and repeated coating can be carried out on the center.

Description

Coating is superhard top
Technical field
The utility model belongs to the Machining Technology field, and particularly coating is superhard top.
Background technology
During machining, to use workpiece top and around the rotating shaft rotation to interact usually.At present, what adopt during machine tooling generally all is that uses on cylindrical grinder, the lathe is top at top top tungsten carbide button or diamond, because leading portion is the material of carbide alloy, so cause service life very short, need repeatedly reconditioning again also not reach very long service time.It is top to adopt the mosaic gold hard rock to do, but the diamond cost than higher, diamond burst apart easily when key was welding, caused expensive monoblock diamond to use, percent defective is higher.Chinese patent application 201010618603.X announces a kind of top and top processing method, provide a kind of top top to be equipped with polycrystalline diamond, but owing to adopt the diamond cost performance not high, and when welding, burst apart easily, thus need that a kind of wearability is good, cost performance is high top.
The utility model content
The utility model provides a kind of coating superhard top for solving above-mentioned the deficiencies in the prior art, increases top wearability and can repeat reconditioning by coating on the carbide alloy on top top.
For achieving the above object, technical solution adopted in the utility model is:
A kind of coating is superhard top, comprises top body and the carbide alloy that is embedded in top top, and described carbide alloy is cylindrical section and the coaxial integrative-structure of conical section, and there are TiC or TiN coating in the conical section surface of described carbide alloy by chemical vapour phase deposition coating.
Described hard alloy coating can repeat coating, repeat reconditioning.
Adopt the obtained beneficial effect of such scheme to be:
The utility model coating is superhard top, on the carbide alloy on top top, by chemical vapour phase deposition coating TiC or TiN are arranged, can reach superhard effect, the physical life of carbide alloy is prolonged greatly, and greatly reduce the top cost of practical diamond, behind coating abrasion, can repeat coating, repeat reconditioning, reach repeatedly and use, the life-span still can not reduce.
Description of drawings
Fig. 1 is the superhard top structural representation of the utility model coating.
The specific embodiment
Referring to Fig. 1,1 is that top body, 2 is that carbide alloy, 3 is TiC or TiN coating among the figure.
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated.
Referring to Fig. 1, the utility model coating is superhard top, comprise top body 1 and carbide alloy 2, carbide alloy 2 is cylindrical section and the coaxial integrative-structure of conical section, carbide alloy 2 is embedded in top body 1 top, for improving top mar proof, in carbide alloy 2 conical tip by the CVD(chemical gaseous phase deposition) scribble TiC or TiN coating 3, can increase the service life greatly, after using wearing and tearing, can carry out coating reparation again, can reach repeatedly and utilize, not only can improve precision, and can reduce cost.

Claims (2)

1. a coating is superhard top, comprise top body and the carbide alloy that is embedded in top top, described carbide alloy is cylindrical section and the coaxial integrative-structure of conical section, it is characterized in that, there are TiC or TiN coating in the conical section surface of described carbide alloy by chemical vapour phase deposition coating.
2. coating according to claim 1 is superhard top, it is characterized in that, described hard alloy coating can repeat coating, repeat reconditioning.
