aluminum milling cutterGenerally divided into three types: aluminum flat knife, aluminum ball knife, aluminum nose knife.

Processing characteristics of aluminum alloy

　　1.aluminum milling cutterCompared with other hardened steels, the hardness of aluminum alloy is lower than that of titanium alloy and other hardened steels. Of course, the hardness of aluminum alloy after heat treatment is also very high, or die-cast aluminum alloy is also very high. The HRC hardness of ordinary aluminum plates is usually lower than HRC40 degrees. Therefore, when processing aluminum alloy, the tool load is small. Aluminum has good thermal conductivity and low cutting temperature for milling aluminum alloy, which improves the milling speed of aluminum alloy.

2. Aluminum alloy has low plasticity and low melting point. The problem of sticking knives in aluminum processing is serious, the chip performance is poor, and the surface roughness is also high. In fact, the processing of aluminum alloy is mainly a rod knife, and the roughness effect is not good. Only by solving the two problems of sticking knives and processing surface quality can the problem of aluminum alloy processing be solved.

Aluminum milling cutter: the tool is not good for wear. When using inappropriate tool materials to process aluminum alloys, tool wear tends to accelerate due to problems such as sticking and chips.

3. Aluminum processing generally use three-day aluminum milling cutter. Due to the difference in processing conditions, it is very possible to use a double-edged ball head or a four-edged flat knife. But in most cases, you can choose a 3-day end mill. The material is generally YG-type cemented carbide, which can reduce the chemical affinity between the tool and the aluminum alloy. Ordinary CNC tool brand has special milling series products for processing aluminum alloy.

4. High-speed steel, high-speed steel, aluminum materials, milling cutter is relatively sharp, aluminum alloy can also be processed well.

5. General aluminum alloy processing can generally choose high-speed on the level. 2. Choose the largest possible front angle to increase the debris space and reduce the knife sticking phenomenon. For finishing aluminum alloy, self-made cutting fluid cannot be used, which can prevent the formation of small pinholes on the machined surface. Generally speaking, kerosene or diesel can be used to make cutting fluid for aluminum plate processing. The cutting speed of aluminum milling cutters depends on the material and parameters of the milling cutter and the machining process. Machining specific cutting parameters may be machined according to the cutting parameters provided by the manufacturer.

Processing aluminum alloy generally use three bladealuminum milling cutterSecondly, due to the difference in processing conditions, it is likely to use a two-blade ball knife or a four-blade flat knife. When processing aluminum alloy, the following factors are also involved: the number of blades for aluminum milling cutters is generally 3 days, and the material for aluminum milling cutters is generally cemented carbide, which can reduce the chemical affinity of aluminum milling cutters and aluminum alloys. High-speed steel material high-speed steel aluminum milling cutter is relatively sharp, aluminum alloy can also be processed well. Processing ordinary aluminum alloy can usually choose high-speed large feed milling. 2. Choose the largest possible front angle to increase the debris space and reduce the phenomenon of knife points;

Steel is also divided into ordinary carbon steel and stainless steel, the material is different, the material of aluminum milling (aluminum milling) may be very different. Especially for processing stainless steel, whether it is end milling (end milling) or side milling (end milling), or end milling (end milling), the processing cost of disc cutter (disc) is low.
