What kind of milling cutter should be used for milling aluminum alloy?

Latest company news about What kind of milling cutter should be used for milling aluminum alloy?

What kind of milling cutter is used for processing aluminum alloy? Is it a special tool for aluminum alloy to make it better? We mainly talk about what milling cutters are used for machining tools and cutting parameters from several aspects of processing tools and cutting parameters.

1. The processing characteristics of aluminum alloy

Milling aluminum alloy mainly has the following major characteristics:

1. Low aluminum alloy hardness

Compared with the titanium alloy and other quenching steel, the hardness of aluminum alloy is low. Of course, the heat treatment is too high, or the hardness of the die -cast aluminum alloy is also very high. The HRC hardness of ordinary aluminum plates is generally below HRC40 degrees. Therefore, when machining aluminum alloy, the carrier of the tool is small. Because of the better thermal conductivity of aluminum alloy, the cutting temperature of the milling aluminum alloy is relatively low, which can improve its milling speed.

2. Low aluminum alloy plasticity

The plasticity of aluminum alloy is low, and the melting point is low. When processing aluminum alloy, its adhesive knife is serious, with poor cripping performance, and the surface roughness is relatively high. In fact, the processing aluminum alloy is mainly the effect of sticky knife and roughness. As long as the two major problems of the sticky knife and the surface quality of the processing are solved, the problem of aluminum alloy processing is solved.

3. The tool is easy to wear

Because the unsuitable tool material is adopted, when processing aluminum alloy, the tool wear is often accelerated due to the problems of sticky knives, crumbs and other problems.

2. What milling cutter is used for processing aluminum alloy?

Machining aluminum alloys are generally used for milling cutters with 3 blade aluminum. Secondly, due to the differences in processing, 2 -edge ball head knives, or 4 blade flat knives. However, in Dahai, Dongguan, it is recommended that in most cases, you can choose a 3 -blade flat bottom milling cutter.

1. Material of high -speed steel

High -speed steel aluminum milling cutter is more sharp, and can also process aluminum alloy well.

2. The choice of aluminum tungsten steel milling cutter

Materials generally choose YG hard alloys, which can reduce the chemical affinity of the tool and aluminum alloy. General CNC -control tool brands have all -in products for processing aluminum alloy.

Third, the cutting parameters of the milling aluminum alloy

Machining ordinary aluminum alloys can generally choose high -speed advance to milling. Secondly, choose the larger front angle as much as possible to increase the space of the crumbs and reduce the phenomenon of sticky knife. If it is precision machining aluminum alloy, a water cutting fluid cannot be used to avoid forming a small pinhole on the processing surface. Generally, kerosene or diesel can be used for processing aluminum plate cutting fluid.

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