In the process of CNC machining, it is often necessary to process products of different materials, and different cutting tools are required for milling. Aluminum milling cutter and HSS milling cutter are two commonly used cutting tools in CNC machining
Aluminum milling cutter is mainly made of carbide structure, mainly cutting aluminum material, and the surface finish of the product is relatively smooth; HSS milling cutter mainly cuts products with low surface requirements, which are relatively cheap but prone to wear and tear.
What Mill Cutter is used for processing aluminum alloy?
We have already learned that aluminum materials are cut using aluminum milling cutters, but there are still many types of aluminum milling cutters. Generally, 3-blade milling cutters are used for processing aluminum alloys. In addition, due to differences in processing conditions, sometimes 2-blade Ball end milling cutters or 4-blade Flat bottom milling cutters are also used. However, it is recommended to choose a 3-blade Flat bottom end mill in most cases.
1. The number of cutting edges for carbide milling cutters used in aluminum is generally 3, and the material is generally hard alloy, which can reduce the chemical affinity between the cutting tool and aluminum alloy.
2. The aluminum milling cutter made of HSS material is relatively sharp and can also process aluminum alloys well.
3. Cutting parameters for milling aluminum alloys
High speed and high feed milling can be chosen for processing ordinary aluminum alloys, followed by selecting larger rake angles as much as possible to increase chip holding space and reduce tool sticking; If it is precision machining of aluminum alloy, water-based cutting fluid cannot be used to avoid the formation of small pinholes on the machining surface. Generally, kerosene or diesel can be used as the cutting fluid for machining aluminum plates. The cutting speed of aluminum alloy milling cutters varies depending on the material, parameters, and processing technology of the milling cutter. The specific cutting parameters can be based on the cutting parameters provided by the manufacturer for proce
