Description

Technical Field

[0001] The utility model relates to the technical field of coated cutting tools, in particular to a nano composite coated cemented carbide cutting tool. Background Art

[0002] Existing technology dissipates heat by spraying cutting fluid onto the tool, but the workpiece is also prone to high temperature during the machining process, causing the cutting fluid on the cutting surface to evaporate quickly, resulting in the cutting fluid being unable to fully cool and lubricate the cutting surface.

[0003] To solve the above problems, the existing public patent (CN215902746U) discloses a nano-composite coated cemented carbide tool with self-lubricating properties, including a tool holder, a blade mounted on the tool holder, a mounting hole provided on one side of the tool holder, a spray head threadedly connected to the mounting hole, a guide hole provided on the top of the tool holder, and a spray assembly installed inside the guide hole. The technical solution uses the provided spray head to allow a part of the cutting fluid to pass through the circular groove of the spray head and spray the cutting fluid onto the blade through the spray hole, and the other part of the cutting fluid passes through the groove of the sliding column and is sprayed onto the workpiece through the vertical hole and the inclined hole. By spraying the cutting fluid on the upper and lower sides of the blade and the workpiece at the same time, the practical life of the blade is improved; through the setting of the spray assembly, the adjusting screw rotates in the thread on the fixed block, and the fixed block drives the sliding column to move up and down to achieve height adjustment of the inclined hole, so that the cutting fluid can be accurately sprayed on the cutting surface.

[0004] However, the spray holes on the spray head of the existing nano-composite coated cemented carbide cutting tools are fixedly arranged on the spray head, and the spray angle of the cutting fluid cannot be adjusted, resulting in poor adaptability. Utility Model Content
