Description
Technical Field
The utility model relates to a cutting tool field, specific theory has related to a coating cutter.
Background
With the rapid development of the machining and manufacturing industry, the requirements of machining on the cutting tool are higher and higher. The coated cutter has good machining performance, so that the cutting performance of the cutter can be greatly improved, the machining efficiency and the machining quality of materials can be improved, and the service life of the cutting cutter can be prolonged.
Various researches on the components and properties of the coating have long shown that the coating mainly has the characteristics of high hardness, high wear resistance, low friction coefficient and the like. However, in the damaged form of the tool, there is a breakage phenomenon of the tool, such as chipping, peeling, crack breakage, etc., in addition to normal tool wear. That is, if the tool is used under certain cutting conditions, if it is not subjected to strong cutting forces or thermal stresses, sudden damage occurs, causing the tool to lose its cutting ability in advance. Therefore, further improvements in impact resistance, chipping resistance, and the like of coated tools are important for improving the tool life.
In order to solve the above problems, people are always seeking an ideal technical solution.
SUMMERY OF THE UTILITY MODEL
In order to realize the purpose, the utility model discloses the technical scheme who adopts is: a coated cutter comprises a cutter base body, wherein a chromium transition layer, an aluminum oxide coating and a titanium-containing compound coating are sequentially deposited on the top of the cutter base body from bottom to top;
the aluminum oxide coating is internally provided with a plurality of microcracks formed by wet sand blasting, dry sand blasting or heat treatment, and the titanium-containing compound coating is internally provided with a plurality of holes formed by introducing carbon dioxide gas in the film coating process.
Based on the above, the thickness of the chromium transition layer is 0.02 μm to 2 μm.
Based on the above, the thickness of the alumina coating is 3 μm to 20 μm.
Based on the above, the thickness of the titanium compound-containing coating layer is 1 μm to 10 μm. Specifically, the selection of the coating thickness is determined by combining the structural strength and wear resistance of the coating itself and the cost of preparing the coating. That is, when the thickness of the coating is relatively thick, the manufacturing cost of the tool is increased, and when the thickness of the coating is relatively thin, the properties of the coating, such as hardness or wear resistance, cannot be normally exerted.
Based on the above, the titanium-containing compound coating is a TiN coating.
Based on the above, the titanium-containing compound coating is a TiCN coating.
Based on the above, the titanium-containing compound coating is a TiCNO coating.
Based on the above, the titanium-containing compound coating is a TiAlN coating.
Based on the above, the titanium-containing compound coating is a TiAlCrN coating.
Based on the above, the titanium-containing compound coating is a TiAlSiN coating.
Wherein the microcracks distributed in the alumina coating can be obtained by wet blasting, dry blasting or heat treatment on the surface of the alumina coating. The holes in the titanium-containing compound coating can be obtained by introducing a certain amount of carbon dioxide gas in the film coating process.
The utility model discloses relative prior art has substantive characteristics and progress, specific theory, the utility model provides a pair of coating cutter is through setting up composite biocoating on the base member surface to with some crazing lines of random distribution in the composite biocoating in the first layer structure, usable crazing line release partly coat inside stress for the coating internal stress reduces, improves the cohesion of coating, is of value to the performance of giving play to the coating. In the second layer structure of the composite coating, holes are randomly distributed in the coating, so that the holes can play a role in buffering impact, and the impact resistance of the coating is further improved.
Furthermore, in material selection, the first coating is selected as an alumina coating, so that the oxidation resistance and the wear resistance of the alumina coating can be fully exerted. The second coating is a titanium-containing compound coating, and holes distributed in the titanium-containing compound coating are utilized to play a certain impact-relieving effect, so that the cutter has high impact resistance when used under severe cutting conditions.
Therefore, the coated cutting tool provided by the utility model has high wear resistance and oxidation resistance, and simultaneously has good combination property and impact resistance; the service performance and the service life of the coated cutter are improved.
