What are the machining technologies of precision mechanical parts?

 Nowadays, the use of precision machining is still more in the industry, because it is a better processing method that can meet the requirements of various products, and it is more in line with people’s requirements, so people If you like it so much, what are the processing technologies of precision mechanical parts?

Ultra-high-speed machining skills refer to modern machining skills that use super-hard materials and greatly improve the cutting speed and feed rate to improve the material removal rate, machining accuracy and machining quality.

The cutting speed limit of ultra-high-speed machining varies with different workpiece materials and different cutting methods. At present, it is generally believed that the cutting speed limits of ultra-high-speed cutting of various materials are: aluminum alloy has exceeded 1600m/min, cast iron is 1500m/min, super heat-resistant nickel alloy is 300m/min, and titanium alloy is 150~1000m/min. The fiber reinforced plastic is 2000~9000m/min.

The cutting speed limits of various cutting processes are: turning 700~7000m/min, milling 300~6000m/min, drilling 200~1100m/min, grinding 250m/s and so on.

Ultra-high-speed machining skills mainly include: ultra-high-speed cutting and grinding mechanism research, ultra-high-speed spindle unit manufacturing skills, ultra-high-speed feed unit manufacturing skills, ultra-high-speed machining tools and abrasive tools manufacturing skills, ultra-high-speed machining online active detection and control Skills etc.

At that time, ultra-fine machining refers to the dimensional accuracy of the processed parts higher than 0.1μm, the surface roughness Ra is less than 025μm, and the machining skills with the resolution and repeatability of the positioning accuracy of the machine tool used are higher than 0.01μm, also known as sub-micron Level processing skills, and is developing towards nano-level processing skills.

Ultra-fine machining skills mainly include: the mechanism study of ultra-fine machining, the equipment manufacturing skills study of ultra-fine machining, the study of ultra-fine machining tools and sharpening skills, the study of ultra-fine measurement skills and error compensation skills, and the study of the prerequisites of ultra-fine machining tasks. .
