Rolling is a plastic deformation process in which the ingot is pulled into the rotating rolls by friction, and the cross section is reduced, the shape is changed, the thickness is thinned and the length is increased by the pressure exerted by the rolls. The following editor will introduce to you what are the characteristics of CNC machining of aluminum alloys? What content can the machining method be divided into? Welcome to read!KnnYoYike manufacturer company

1. Aluminum alloy has low hardnessKnnYoYike manufacturer company

Compared with titanium alloy and its quenched steel, the hardness of aluminum alloy is lower, of course, the hardness of heat-treated or die-cast aluminum alloy is also very high. The HRC hardness of ordinary aluminum plates is generally below HRC 40 degrees. Therefore, when machining aluminum alloys, the load of the tool is small. And because the thermal conductivity of aluminum alloy is better, the cutting temperature of milling aluminum alloy is relatively low, which can improve the milling speed.KnnYoYike manufacturer company

2. Aluminum alloys have low plasticityKnnYoYike manufacturer company
 KnnYoYike manufacturer company
Aluminum alloy has low plasticity and low melting point. When machining aluminum alloys, the sticking problem is serious, the chip removal performance is poor, and the surface roughness is relatively high. In fact, the machining of aluminum alloy is mainly due to the poor effect of sticking and roughness. As long as the two major problems of sticking the knife and the quality of the machined surface are solved, the problem of aluminum alloy machining will be solved.KnnYoYike manufacturer company

According to the machining method, aluminum alloys can be divided into two categories: deformed aluminum alloys and cast aluminum alloys: deformed aluminum alloys can withstand pressure machining. It can be processed into aluminum alloys of various shapes and specifications. Mainly used in the manufacture of aviation equipment, doors and windows for construction, etc.KnnYoYike manufacturer company

Deformed aluminum alloys are divided into non-heat-treatable-strengthened aluminum alloys and heat-treatable-strengthened aluminum alloys. The non-heat-treatable strengthening type cannot improve mechanical properties through heat treatment, but can only be strengthened through cold working deformation. It mainly includes high-purity aluminum, industrial high-purity aluminum, industrial pure aluminum, and rust-proof aluminum.KnnYoYike manufacturer company

Heat-treatable-strengthened aluminum alloys can improve their mechanical properties by means of heat treatment such as quenching and aging. They can be divided into hard aluminum, forged aluminum, super-hard aluminum, and special aluminum alloys.KnnYoYike manufacturer company

Casting aluminum alloys can be divided into aluminum-silicon alloys, aluminum-copper alloys, aluminum-magnesium alloys, aluminum-zinc alloys and aluminum-rare-earth alloys according to their chemical composition. Crystal silicon aluminum alloy and cast aluminum alloy are used in the as-cast state.
