Abstract
The utility model discloses a coating structure of a machine tool cutter. The coating structure comprises a cutter body and a hard alloy embedded at the top of the cutter body, wherein the hard alloy is in a coaxial integrated structure composed of a cylindrical section and a conical section; the surface of the hard alloy is provided with a zirconium oxide high-temperature-resisting and heat-insulating coating; the surface of the zirconium oxide high-temperature-resisting and heat-insulating coating is provided with a wear-resisting coating. The coating structure of the machine tool cutter has the beneficial effects that the arranged heat-insulating coating and the surface of a tool have good bonding strength; meanwhile, the zirconium oxide heat-insulating coating has a good heat-insulating effect and the high-temperature-resisting requirements of cutting and machining for long time can be met; the arranged wear-resisting coating can be used for effectively improving the wear-resisting performance of the surface of the tool so that the cutter has a long service life.
Description
Technical field
The utility model relates to machining tool technical field, relates in particular to a kind of coating structure of machine tool.
Background technology
At present, what when machine tooling, adopt is all generally at top top tungsten carbide button or diamond, the cutter using on cylindrical grinder, lathe, because leading portion is the material of carbide alloy, so cause service life very short, needs repeatedly reconditioning again also not reach very long service time.Adopt mosaic diamond to do top, but diamond cost is higher, when key is welding, diamond easily bursts apart, and causes expensive monoblock diamond to use, and percent defective is higher, has potential safety hazard, is unfavorable for normally carrying out of activity in production.
Utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of wearability and heat resistance that can effectively improve tool surfaces, meets the coating structure of the machine tool of machining production requirement.
The technical scheme that the utility model adopts is: a kind of coating structure of machine tool, comprise cutter body, be embedded in the carbide alloy at cutter body top, described carbide alloy is cylindrical section and the coaxial integrative-structure of conical section, the surface of described carbide alloy is provided with zirconia high temperature resistant heat insulation coating, and the surface of described zirconia high temperature resistant heat insulation coating is provided with wear-resistant coating.
As preferably, described wear-resistant coating is for to have TiC or TiN coating by chemical vapour phase deposition coating.
As preferably, the thickness of described zirconia high temperature resistant heat insulation coating is 0.2 nanometer～200 nanometer.
Compared with prior art, the beneficial effects of the utility model are: the thermal insulation layer of setting and tool surfaces have good bond strength, simultaneous oxidation zirconium heat insulating coat has good effect of heat insulation, can meet the high temperature resistant demand of long-time machining, the wear-resistant coating arranging can effectively improve the anti-wear performance of tool surfaces, makes cutter have longer service life.
