Description

Technical Field

[0001] The utility model relates to the technical field of diamond cutting tools, in particular to a coating device for diamond cutting tools. Background Art

[0002] Single crystal diamond is extremely brittle and cannot adapt to high-strength or high-impact load processing environments. Therefore, the application of single crystal diamond tools is limited due to the high cost and poor impact resistance. Diamond coated tools are widely used in various fields because of their simple preparation process, low cost, and the advantages of both diamond and matrix. They can also be made into various complex geometric shapes. During the coating process, the existing diamond tool coating device soaks the tool into the film-forming agent, which will contaminate the film-forming agent and is not conducive to the subsequent coating of the tool. After coating, the tool needs to be manually removed from the tool holder, resulting in low efficiency of coating processing. Utility Model Content
