Solutions for CNC aluminum alloy machining materials

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

How to better gain a competitive advantage in the fierce industry? It is to make it the most refined in the tool industry, machine tool industry and fixture industry through some difficult processing materials.

One of the properties like aluminum alloys is work hardening. Large shear angles during machining result in thin chips and a relatively small contact area on the tool.

In addition, the high cutting force during machining, combined with the frictional force during chip flow, can lead to excessive local cutting heat of the tool. However, the thermal conductivity of titanium alloys is poor, resulting in that the heat generated cannot be conducted well.

Therefore, a large amount of cutting heat is concentrated on the cutting edge and the tool surface. High cutting force and cutting heat will comprehensively cause the generation of craters and rapid tool failure.

These factors lead to poor product quality and high tool wear and tear, which is a problem that enterprises have to consider. Aluminum alloys are more elastic than steel because of their relatively low elastic modulus. Therefore, in order to ensure that the rebound of the workpiece is small, excessive cutting force should be avoided. Thin-walled parts often have a tendency to deform under tool pressure, as well as causing chatter, friction and even tolerance issues.

The key to solving these problems is to ensure the rigidity of the whole system. It is very necessary to use a tool with a sharp cutting edge and correct geometry! In addition, aluminum alloys have a tendency to chemically react with cutting tools to alloy at high temperatures, and their chips have a tendency to weld to the surface of the tool. These are all factors to consider!

Aluminum alloy processing equipment needs to be able to process small and complex parts made of difficult-to-machine materials (such as aluminum alloy or stainless steel) with high precision requirements, such as replacement parts for processing bones and joints. complex.

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

Workpieces are usually processed on international advanced CNC aluminum alloy processing equipment such as Swiss automatic lathes, multi-spindle machine tools and rotary tables. Most of these machine tools are characterized by very small size and very compact 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 manufacturers in CNC aluminum alloy processing.
