At present, the processing of aluminum parts is mainly divided into two categories of wrought aluminum alloy and cast aluminum alloy, so what milling cutter is used for processing aluminum alloy? Is it with aluminum alloy special milling cutter or aluminum alloy special tool, its processing efficiency is better? This article from the milling characteristics of aluminum alloy, processing tools, cutting parameters of several aspects to talk about the processing of aluminum alloy with what milling cutter is the best. Processing characteristics of 1. aluminum alloy Milling aluminum alloy mainly has the following characteristics; 1. Low hardness of aluminum alloy Compared with titanium alloy and other hardened steel, the hardness of aluminum alloy is lower, of course, heat treatment, or die casting aluminum alloy hardness is also very high. The HRC hardness of ordinary aluminum plate is generally below HRC40. Therefore, when processing aluminum alloy, the load of the tool is small. Because of the better thermal conductivity of aluminum alloy, the cutting temperature of milling aluminum alloy is relatively low, which can improve the milling speed. 2. Aluminum alloy with low plasticity Aluminum alloy has low plasticity and low melting point. When processing aluminum alloy, the sticking knife problem is serious, the chip removal performance is poor, and the surface roughness is relatively high. In fact, the processing of aluminum alloy is mainly stick knife and roughness effect is not good. As long as the two major problems of sticking knives and surface quality are solved, the problem of aluminum alloy processing will be solved. 3, the tool is easy to wear Because the tool material is not suitable for the processing of aluminum alloy, often because of sticky knife, chip and other problems lead to accelerated tool wear. 2. processing aluminum alloy with what milling cutter? Generally, 3-blade aluminum milling cutters are used for processing aluminum alloys. Secondly, due to differences in processing conditions, 2-blade ball-end cutters or 4-blade flat-bottomed cutters are likely to be used. However, Nanjing Arrow Piercing Stone recommends that in most cases, a 3-blade flat-bottomed end mill can be used. 1. Selection of tungsten steel milling cutter for aluminum The number of blades is generally 3 blades, and the material is generally selected as YG cemented carbide, which can reduce the chemical affinity between the tool and the aluminum alloy.

The specific cutting parameters can be processed on the basis of the cutting parameters given by the manufacturer.

Processing characteristics of 1. aluminum alloy

Milling aluminum alloy mainly has the following characteristics;

1. Low hardness of aluminum alloy

Compared with titanium alloy and other hardened steel, the hardness of aluminum alloy is lower, of course, heat treatment, or die casting aluminum alloy hardness is also very high. The HRC hardness of ordinary aluminum plate is generally below HRC40. Therefore, when processing aluminum alloy, the load of the tool is small. Because of the better thermal conductivity of aluminum alloy, the cutting temperature of milling aluminum alloy is relatively low, which can improve the milling speed.

2. Aluminum alloy with low plasticity

Aluminum alloy has low plasticity and low melting point. When processing aluminum alloy, the sticking knife problem is serious, the chip removal performance is poor, and the surface roughness is relatively high. In fact, the processing of aluminum alloy is mainly stick knife and roughness effect is not good. As long as the two major problems of sticking knives and surface quality are solved, the problem of aluminum alloy processing will be solved.

3, the tool is easy to wear

Because the tool material is not suitable for the processing of aluminum alloy, often because of sticky knife, chip and other problems lead to accelerated tool wear.

2. High-speed steel material

High-speed steel aluminum milling cutter is more sharp, can also be a good processing of aluminum alloy.

Cutting Parameters of 3. Milling Aluminum Alloy

Processing ordinary aluminum alloy can generally choose high-speed large feed milling. Secondly, as far as possible to choose a larger front angle, increase the chip space, reduce the phenomenon of sticking knife. If it is a finishing aluminum alloy, you can not use the water agent cutting fluid, to avoid the formation of small pinholes in the processing surface, generally can use kerosene or diesel oil to do the processing of aluminum plate cutting fluid.

The cutting speed of the aluminum alloy milling cutter is different due to the material and parameters of the milling cutter and the different processing technology. The specific cutting parameters can be processed on the basis of the cutting parameters given by the manufacturer.
