Description

Technical Field

[0001] This utility model relates to the field of cutting tool processing technology, and in particular to a grinding device for PCD cutting tool processing that prevents chip splashing. Background Technology

[0002] PCD cutting tools are widely used in cutting difficult-to-machine materials in aerospace, automotive manufacturing, precision electronics and other fields due to their ultra-high hardness, wear resistance and long life. However, the ultra-high hardness of PCD material makes it difficult to process. The chips generated by PCD grinding are small in size and high in temperature. They may burn operators or damage equipment after splashing. Therefore, it is necessary to design a grinding device for PCD cutting tool processing that prevents chip splashing.

[0003] To address this, patent CN214109794U discloses a tool grinding device for machining, relating to the field of machining equipment technology. It includes a worktable and a placement slot located at the upper end of the worktable. A housing is fixedly connected to the upper end of the worktable, and a fixing mechanism for fixing the tool is provided on the worktable. The fixing mechanism includes a rotating shaft rotatably connected to the side wall of the housing. This invention eliminates the need for manual adjustment during the grinding process and automatically rotates the tool, saving time and effort and improving work efficiency. Furthermore, it prevents debris from scattering everywhere, and the debris falls along the inclined surface of the feed plate into a filter basket, effectively avoiding the need for repeated cleaning of the floor and worktable, which is time-consuming. Additionally, it cools the tool surface, preventing any impact on the tool's machining accuracy and the surface roughness.

[0004] Although the aforementioned tool grinding device can cool the tool surface during use, it relies solely on the gravity of the chips to fall into the collection box, resulting in low collection efficiency. Therefore, it is necessary to design a PCD tool grinding device that prevents chip splashing. Utility Model Content
