What is 5-axis milling? Application of 5-axis milling.
There are many manufacturing tasks for which 3 + 2 positioning axis milling is sufficient and even has advantages. But at the latest when it comes to free-form surfaces, there is no way around 5-axis simultaneous milling.
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.
Common surface treatment of processed prototypes: grinding, polishing, electroplating, oxidation, passivation, blackening, phosphating, etc.
In the entire process of prototype processing, after selecting the appropriate processing method (CNC processing or 3D printing), most of the prototypes require surface treatment. The purpose of surface treatment is to meet the product’s corrosion resistance, wear resistance, decoration or other special functional requirements. There are dozens of surface treatment processes for prototype processing. Next, we will introduce the common surface treatment processes for prototype processing.
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.
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 project of aluminum alloy heat sink prototype. Its processing method is CNC processing, and the surface treatments used include sanding, laser engraving and sandblasting.
CNC machining: cnc tool apparatus above, according to the programmed path, the motion in the above material, the excess material is removed portion, whereby the prototype of the prototype model.
Large-scale multiple input multiple output technology is one of the core technologies of 5G. Using multi-antenna space division multiplexing to double the spectrum efficiency, enhance network coverage and system capacity. Massive MIMO uses more than 100 antennas, which is an order of magnitude higher than that of traditional base stations. Therefore, more independent data streams can be transmitted between the system and the terminal, thereby exponentially improving spectrum efficiency and energy efficiency. The increase in the number of antennas directly leads to the difference in signal processing methods, causing new problems and challenges.
The prototype CNC machining can process a wide variety of materials. Plastic materials are: ABS, PMMA, PP, PC, POM, nylon, bakelite, etc. Metal materials include: aluminum, magnesium and zinc alloys, copper, steel, iron, titanium, etc. There are many types of CNC prototypes that can be met, and they are currently widely used in China.
For some low-volume or single-piece rapid prototyping manufacturing, turning and milling processing equipment is also very versatile. Because of its ability to control at least one rotary axis, its application range has been expanded, and it can even replace the work of a multi-coordinate linkage CNC machining center.
