What are the precision parts processing technologies?

  Ultra-high speed machining technology is an important part of precision part processing technology. Because precision machining has high requirements for accuracy, it can only tolerate extremely small errors. Therefore, it is necessary to focus on machine tool processing and super-hard materials to solve these problems, and to improve the cutting speed of materials by improving the high-precision machining capability of the machine tool.

So what is the ultra-high-speed machining skill? Let's take a look at it in detail:

Ultra-high-speed machining skills refer to modern machining skills that use cutting tools with super-hard materials to improve material removal rate, machining accuracy and machining quality through extremely high cutting speeds and feed rates.

The cutting speed limitations of ultra-high speed machining vary depending on the workpiece data and the different cutting methods. The cutting speed limits of various types of ultra-high-speed cutting materials are: aluminum alloy 1600m/min, cast iron 1500m/min, super heat-resistant nickel alloy 300m/min, titanium alloy 150~1000m/min, fiber reinforced plastic 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 more than 250m/s and so on.

Ultra-high-speed machining skills 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 manufacturing skills, ultra-high-speed machining online active detection and control Skills, etc.

Ultra-fine machining refers to the machining accuracy of the machined parts with a dimensional accuracy of more than 0.1μm, the appearance roughness Ra of less than 0.25μm, and the resolution of the machine tool used and the repeatability of more than 0.01μm, also known as sub-micron. Level processing skills and are working on nanoscale processing skills.

Superfine processing skills include: research on the mechanism of ultra-fine processing, equipment manufacturing skills research in ultra-fine processing, ultra-fine processing and sharpening skills research, ultra-fine measurement skills and error compensation skills, superfine processing tasks, premise discussion .
