Machining of large and thin-walled aluminum parts

For CNC machining of aluminum parts with a large margin (large, thin-walled, aluminum cavity parts), in order to have better heat dissipation conditions during the machining process and avoid heat concentration, symmetric machining should be used during machining. If there is a 90mm thick aluminum sheet that needs to be machined to 60mm, if one side is milled, the other side should be milled immediately, and the flatness can only reach 5mm after processing to the final size at a time;

How to solve the deformation of thin parts in CNC machining?

Turning and milling thin parts (aluminum, aluminum alloy, pure titanium, copper, magnesium alloy) are always prone to deformation during machining. Oval or “waist shape” with a small middle and large ends, which makes it difficult to ensure the quality of parts. Its clamping design is often the most discussed point. Let’s take a look at two design examples of thin-walled fixtures on turning and milling parts, and how they solve the deformation problem.

CNC machining laser aluminum alloy cavity prototype

High diffuse reflection laser cavity is mainly used for the production of pump cavity for solid and liquid laser devices. The structure adopts a tightly packed form, and uses a high-reflectivity diffuse reflection material as the reflector of the pump light source. Due to the design and structural characteristics of the highly diffuse reflection laser cavity, the energy of the pump light source is evenly distributed in the pump cavity, so that the laser material can absorb energy in a balanced manner.

CNC Machining of Roller Die of N95 Mask Machine

The selection of reasonable turning and milling parameters not only ensures the high precision of the finishing of the mask machine accessories (N95 embossing die roller). It is also a guarantee for high-speed machine tools to be effective and in the best working condition. Therefore, the cutting amount depends on the rigidity of the machine tool, the diameter of the milling tool, the length of the tool, the workpiece material, and the roughing or finishing mode.

CNC machining aluminum alloy cavity used in aerospace

The aluminum alloy cavity is used in aerospace products. Milling parameters (difficulty): product height 315mm, internal R20, flatness 0.05, parallelism 0.02, roughness 1.6.
The aluminum cavity is a shell of an aerospace component customized for an aerospace manufacturing company. The aluminum cavity is a high-precision and difficult CNC milling cavity. The processing depth is as high as 315mm, and the accuracy requirements for parallelism and flatness are very high. Since I signed a non-disclosure agreement with the client, the details will not be described again.

The roller is the main part of the rolling mill. It is subject to a certain impact during actual use, and the surface is rubbed by high-speed, high-temperature red steel. The surface is required to have good abrasion resistance, and at the same time, it must have sufficient toughness to prevent it from being broken by impact.
