Reaming of aluminum reaming parts generally adopts carbide, coated carbide, and PCD reamers. Generally, the built-up edge is the biggest problem in processing aluminum parts. The generation of built-up edges will lead to adverse effects such as enlarged pore size and excessive roughness.
On the whole, the PCD reamer can use a higher linear speed, effectively avoiding the generation of a built-up edge.
But if the cemented carbide tool is designed properly, it can also be processed with good precision. Especially for the use of coated tools, the correct selection of the corresponding coating can not only meet the accuracy requirements, but also have the advantages of stable wear resistance and chemical properties, heat resistance and oxidation resistance, small friction factors, and low thermal conductivity. However, coated blades are not as sharp as uncoated knives because the cutting edge is passivated when the knives are coated. The sharp cutting edge can also effectively prevent the formation of a built-up edge, so the processing of aluminum alloy tools is generally not coated.
