Description

Technical Field

[0001] This utility model relates to the field of diamond tool manufacturing, specifically to a single-crystal diamond forming high-gloss end mill for aluminum. Background Technology

[0002] The processing technology is mainly applied to the processing of aluminum alloy (AL6063) materials. In actual processing, extremely stringent requirements are placed on product quality.

[0003] In terms of shape and outline, precision is paramount. Every line and angle must strictly conform to design standards to ensure the product achieves optimal performance in both appearance and function. Dimensional accuracy is equally crucial; even minute deviations can affect assembly and usability. Therefore, the manufacturing process requires precise control of every dimensional parameter.

[0004] The grooves and grain are also a key factor affecting product quality. Fine, uniform grooves not only enhance the product's appearance and texture but also prevent stress concentration issues caused by groove problems, thus improving the overall quality of the product. Surface quality is paramount; a smooth, flat surface not only enhances the product's aesthetics but also reduces friction and wear during use.

[0005] In addition, tool life is also a key factor to consider. Due to the characteristics of aluminum alloy (AL6063), tool wear is significant during machining. If tool life is too short, it will not only increase production costs but may also affect machining efficiency and product quality. Therefore, throughout the machining process, it is necessary to comprehensively consider various factors and continuously optimize the machining process to meet the high requirements for product shape and contour, dimensional accuracy, tool marks, surface quality, and tool life.
