Description

Technical Field

[0001] This utility model relates to the field of diamond end mill preparation, specifically to a single-crystal diamond forming end mill for aluminum alloy machining. Background Technology

[0002] Aluminum alloy (AL6063) is widely used in many industries due to its unique performance advantages. However, processing it into products that meet requirements is not easy. The processing involves extremely stringent requirements for various product specifications.

[0003] In terms of product shape and outline, a high degree of precision is required. Every line and every curve must perfectly match the design requirements without the slightest deviation. Dimensional accuracy is even more critical and must be strictly controlled within an extremely small tolerance range to ensure that the product functions properly during subsequent assembly and use.

[0004] Regarding blade marks, they should be minimized or eliminated as much as possible, because obvious blade marks not only affect the appearance of the product but may also adversely affect its performance. Surface quality is equally important; it must be smooth, flat, and free of flaws and defects to meet high-quality usage requirements.

[0005] In addition, tool life is also an important consideration. Due to the characteristics of aluminum alloy (AL6063), tool wear is significant during machining. Therefore, effective measures need to be taken to extend tool life, reduce production costs, and improve production efficiency. Only by fully meeting these requirements can high-quality machining of aluminum alloy (AL6063) be achieved. Utility Model Content
