The subject needs to process a softer metal, and cannot use coolant (which will cause pollution), and does not produce local high temperature (below 600 degrees). The part is a cylinder with a diameter of not more than 20mm, with grooves on it and the axis The deep blind hole has a machining accuracy of 0.01mm.

No best answer

1.At least you need to know the density, hardness, tensile strength, yield strength, main components and other parameters of the part. The processing technology below 600 degrees actually does not have such a high temperature for conventional turning, milling, drilling and grinding, but it depends on the hardness of the material. , The conventional processing technology of aluminum parts will not exceed 600 degrees, and the temperature generated on the surface of the material by wire cutting and electric discharge will not be higher than that of turning, milling, drilling and grinding.
2.The processing of lithium-based alloys is simply a small knife walking at a high speed. The requirements for the knife are usually very high, and special knives are required; in addition, the bed must be able to run at a high speed, without a speed of 2w or more. The scrap rate after processing is usually very alarming; in addition, it should be possible Use oil mist to cool (but think carefully about the oil), otherwise the programmer's ability to move the knife will be tested.
3.For external grooves, you can try a slow-tool servo with a high-speed milling axis; for blind holes with a relatively large depth-to-diameter ratio, ultrasonic cavitation drilling can be used if the size is large, and a femtosecond laser can be used for small size (micron level).
