Solutions for CNC aluminum alloy processing materials

Aluminum alloy processing has gradually grown in the CNC processing industry in recent years, and many CNC processing plants are also continuing to achieve better turning centers and good tools, in order to better gain competitive advantages in the fierce industry.

So how can we better gain a competitive advantage in a fierce industry? It is to make it the most exquisite in the tool industry, machine tool industry, and fixture industry through some difficult processing materials.

Just like aluminum alloys are one of the characteristics that are process hardening. During the processing process, the shear angle is large, the chips are produced, and a relatively small contact area will be formed on the tool.

In addition, the high cutting force during processing, combined with the friction force during chip flow, these factors will cause the local cutting heat of the tool to be too high. Titanium alloy has poor thermal conductivity, which causes the heat generated to be unable to be well transmitted.

Therefore, a large amount of cutting heat is concentrated on the cutting edge and the tool surface. High cutting force and cutting heat will cause the occurrence of crescent depressions and will also cause the tool to fail quickly.

The product quality caused by these factors and the high loss of tools are a problem that enterprises have to consider. The elasticity of aluminum alloys is better than steel because of its relatively low elastic modulus. Therefore, in order to ensure that the workpiece rebound is small, excessive cutting force should be avoided. Thin-walled parts usually tend to deform under tool pressure, and can also cause problems such as tremor, friction and even tolerance.

The key to solving these problems is to ensure the rigidity of the entire system. It is very necessary to use sharp cutting edges and correct geometric tools! In addition, aluminum alloys tend to undergo chemical reaction with cutting tools at high temperatures, and chips tend to be welded to the surface of the tool. These are all factors that have to be considered!

Aluminum alloy processing equipment needs to be able to process small and complex parts made of difficult-to-process materials (such as aluminum alloy or stainless steel) with high precision requirements. For example, processing alternatives to bones and joints is quite complicated.

Another factor that increases machining complexity is the narrow tolerance range. CNC aluminum alloy processing materials, processing accuracy, surface finish, etc. are very high, all of which require high reliability of the processing system. Therefore, extremely high requirements are put forward for machine tools, fixtures, tools, CAM software, etc.

Workpieces are usually processed on internationally advanced CNC aluminum alloy processing equipment such as Swiss automatic lathes, multi-spindle machines and slewing workbenches. Most of these machine tools are very small in size and very compact in structure.

The characteristics and requirements of CNC aluminum alloy processing undoubtedly promote the development of processing technology and solutions to improve the competitiveness and production efficiency of CNC aluminum alloy processing in small and medium-sized enterprises.
