Many people will ask what imported CNC cutting tool brand is used for processing milling aluminum alloy? At present, the processing aluminum parts used are mainly divided into two categories: deformed aluminum alloy and cast aluminum alloy, so what milling tool is used for processing aluminum alloy, is it a special milling tool for aluminum alloy or a special tool for aluminum alloy, whose processing efficiency is better? In this article, we will talk about what milling tool is best for machining aluminum alloy from several aspects, such as the milling characteristics of aluminum alloy, processing tool and cutting parameters.

First, the processing characteristics of aluminum alloy. Milling aluminum alloy mainly has the following major characteristics.

1, aluminum alloy hardness is low

Compared with titanium alloy and other hardened steel, the hardness of aluminum alloy is low, but of course the hardness of heat-treated, or die-cast aluminum alloy is also very high. The HRC hardness of ordinary aluminum plate is generally below HRC40 degrees. Therefore, when machining aluminum alloy, the tool load is small. And because of the better thermal conductivity of aluminum alloy, the cutting temperature of milling aluminum alloy is relatively low, which can improve its milling speed.

2, Aluminum alloy with low plasticity

The plasticity of aluminum alloy is low, and the melting point is also low. When machining aluminum alloy, its sticky tool problem is serious, the chip removal performance is poor, and the surface roughness is relatively high. In fact, machining aluminum alloy is mainly about sticky knife and bad roughness effect. As long as we solve the two problems of sticky tool and surface quality, the problem of aluminum alloy processing will be solved.

3, The tool is easy to wear

Because of taking unsuitable tool material, when machining aluminum alloy, the tool wear is often accelerated because of sticky tool and chip discharge.

milling cutter

Second, what milling cutter is used for machining aluminum alloy

Aluminum milling cutters are generally used for processing aluminum alloy with 3 edges, followed by 2-blade ball end cutters or 4-blade flat bottom cutters because of the difference in processing conditions. German KHC tungsten steel milling cutter brand suggests that in most cases, you can use 3-flute flat-bottom milling cutters. The number of edges is usually 3 and the material is usually chosen to be monolithic carbide, which reduces the chemical affinity of the tool to the aluminum alloy. General CNC tool brands have special milling cutter series for processing aluminum alloy, such as Germany KHC CNC tool brand, aluminum alloy special series of tools using scientific tool design, advanced edge processing technology, very good processing surface effect, suitable for aluminum alloy material high-efficiency processing.

Third, the cutting parameters of milling aluminum alloy

Machining common aluminum alloy can generally choose high-speed large feed milling. Next, choose a larger front angle as much as possible to increase the chip space and reduce the phenomenon of sticky tool. If it is finishing aluminum alloy, you cannot use water cutting fluid to avoid forming small pinholes on the processing surface, generally you can use kerosene or diesel oil as the cutting fluid for processing aluminum plate.

The cutting speed of machining aluminum alloy milling cutter varies according to the material and parameters of the milling cutter and the machining process. Specific cutting parameters can refer to the cutting parameters given by the manufacturer as the basis for processing.
