CNC Milling is a process where a milling tool cuts away the material in a rotary motion. It allows manufacturers to shape raw materials into specific forms, creating components with desired dimensions and geometries. Milling machines can also achieve extremely tight tolerances and high precision.

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.

Aluminum prototype of AAU module

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.

cnc milling of stainless steel parts

The characteristics of milling stainless steel are: stainless steel has strong adhesion and fusion, and the chips are easy to adhere to the teeth of the milling cutter, which makes the milling conditions worse;
When up-milling, the cutter teeth slide on the hardened surface first, which increases the tendency of work hardening; When milling, the impact and vibration are large, which makes the cutter teeth of the milling cutter easy to chip and wear.
