In the previous article we introduced the form of machining
Ultra-high-speed machining technology is a very important part of precision component processing technology, because precision machining requires high precision and can only tolerate small errors. Therefore, we must focus on the processing of machine tools and superhard materials to solve these problems, and improve the machine's high-precision machining capabilities to solve the material cutting speed.
So what is the ultra-high-speed machining skill? Here's a detailed look at it:
Ultra-high-speed machining skills refer to cutting tools that use super-hard data, and have greatly improved cutting speed, feed speed, and modern processing skills that improve data removal rates, machining accuracy, and machining quality.
The cutting speed limitations of ultra-high-speed machining vary depending on the workpiece data and the method of cutting. At present, it is generally believed that the speed limit for ultrahigh-speed cutting of various materials is limited to: aluminum alloy exceeding 1600m/min, cast iron 1500m/min, superheat-resistant nickel alloy 300m/min, and titanium alloy 150-1000m/min. Fiber-reinforced plastics are 2000~9000m/min. The cutting speed of various types of cutting processes is limited to: turning 700~7000m/min, milling 300~6000m/min, drilling 200~1100m/min, grinding 250m/s and so on.
The ultra-high-speed machining skills mainly include: research on ultra-high-speed cutting and grinding mechanism, 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.
Super-finishing machining refers to the dimensional accuracy of the machined parts is higher than 0.1μm, the rough roughness Ra is less than 025μm, and the precision and repeatability of the used machine tool positioning accuracy is higher than 0.01μm, also known as submicron Level processing skills, and is being developed to nano-scale processing skills.
Superfine machining skills include: research on the mechanism of ultra-fine processing, research and development of ultra-fine processing equipment manufacturing skills, research on ultra-fine processing of materials and sharpening skills, research on ultra-fine measurement skills and error compensation skills, and research on ultra-fine processing tasks
