Embodiment Construction

[0045] The technical solutions of the present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0046] The present invention has the technical scheme of the diamond cutting tool of composite structure coating, comprises base body 1 and as the cutting edge layer 2 of cutting part, and described cutting edge layer 2 comprises the electrodeposited metal layer 4 that is affixed with superhard coarse particle 3, and described electrodeposition The deposited metal layer 4 is attached to the substrate 1 by the first electroplating method, and the high wear-resistant layer 5 is attached to the electrodeposited metal layer 4 by the second electroplating method, and the electrodeposited metal layer 4 is made of nickel sulfamate. The main salt is nickel or nickel-cobalt alloy, and superhard fine grains 6 are inlaid in the high wear-resistant layer 5. In the conventional design, the superhard coarse grains 3 expose the high ...

Abstract

The invention discloses a diamond cutting tool with a coating of a composite structure. The diamond cutting tool comprises a base body and a cutting edge layer. The cutting edge layer comprises the coating of the composite structure, and the coating is fixedly connected with coarse super-hard grains. The coating of the composite structure comprises an electro-deposition metal layer at the lower layer and a high-abrasion-resistance layer at the upper layer. Fine super-hard grains are fixedly connected in the high-abrasion-resistance layer. A manufacturing method of the diamond cutting tool includes the steps that an electroplated diamond tool serves as a basis, and the high-abrasion-resistance layer is compounded on the electroplated diamond tool to form the diamond tool coating of the composite structure. The cutting edge layer is protected by the high-abrasion-resistance layer, the situation that the diamond tool loses efficacy rapidly due to falling off of part of the coarse super-hard grains in the use process is avoided, the service life of the diamond tool is prolonged effectively, and the effect for a flexible diamond tool is especially outstanding; meanwhile, the diamond cutting tool can be used as a reinforcement means after the diamond tool loses efficacy, and the service life of the diamond tool is prolonged effectively.

Description

[0001] (1) Technical field: [0002] The invention relates to a cutting tool, in particular to a diamond cutting tool with a composite structure coating and a manufacturing method thereof. [0003] (two) background technology: [0004] Diamond tools are mainly used for processing hard and brittle materials (such as: sapphire, special ceramics, monocrystalline silicon, precious jade, etc.). Among them, the service life is an important index to measure the diamond tool. The failure of the diamond tool is mainly due to the wear and tear failure of the diamond blade layer and the fracture failure of the insufficient strength of the matrix. According to the investigation and experimental results, the failure mode of diamond tools often starts from the weakest point. When the diamond blade layer falls off at a certain point, the entire coating will start to fall off continuously from the vicinity of the particle drop-off point, and eventually lead to The entire tool fails. The actu...
