Description

Technical Field

[0001] This utility model relates to the field of diamond tool manufacturing, specifically to a PCD diamond reamer with double guide edges. Background Technology

[0002] In the field of ultra-precision machining of hole structures in non-ferrous and non-metallic materials, the requirements for various indicators are extremely stringent.

[0003] Product precision is the primary consideration. High-precision hole machining ensures accurate product dimensions, meets the requirements of various precision equipment, and avoids affecting overall performance and stability due to minor errors.

[0004] Surface finish is equally important. Smooth and delicate pore walls not only give products a good visual effect, but also reduce friction loss and improve product durability and corrosion resistance, which is especially important in aerospace, electronic equipment and other fields.

[0005] Tool life is also a key indicator. During machining, tools need to have good wear resistance and stability to reduce the increased costs and reduced production efficiency caused by frequent tool changes.

[0006] Only by fully meeting these high requirements can high-quality non-ferrous and non-metallic porous structure products be produced. This requires not only advanced processing technology and equipment, but also strict control over every step of the processing to ensure that product quality meets high standards.
