Description

Technical Field

[0001] This utility model relates to the field of diamond tool manufacturing, specifically to a PCD diamond tool with a blade-type structure. Background Technology

[0002] In the field of machining non-ferrous and non-metallic materials, the requirements for various product specifications are extremely stringent.

[0003] Product precision is paramount, serving as a key factor in measuring product quality. High-precision machining ensures the dimensional accuracy of both non-ferrous and non-metallic components, meeting the requirements of various precision equipment. Even extremely minute dimensional deviations can affect the performance and stability of the entire device; therefore, precision must be controlled within an extremely small range.

[0004] Surface finish is equally important. A smooth and delicate processed surface not only enhances the product's appearance and texture, but more importantly, it reduces friction loss, lowers energy consumption, and extends the product's lifespan.

[0005] Tool life is also a crucial indicator. During turning, tools must possess excellent wear resistance and stability to minimize the increased costs and reduced production efficiency caused by frequent tool changes. Only by fully meeting these high requirements can high-quality non-ferrous and non-metallic machined products be produced. Utility Model Content
