Ultra-high-speed machining technology is a very important part of precision parts processing technology, because precision machining requires high accuracy and can only tolerate very small errors. So we have to focus on machine tool processing and super hard material above to solve these problems, by improving the machine tool's high precision processing capability to solve the material cutting speed and so on.
So what is the ultra-high-speed machining skills, we will look at the following in detail.
Ultra-high-speed machining skills refers to the use of super-hard material cutting tools, after greatly improving the cutting speed and feed rate to improve the material removal rate, processing accuracy and processing quality of modern processing skills.
The cutting speed limitation of ultra-high-speed machining varies according to the different workpiece materials and different cutting methods. At present, it is generally believed that the cutting speed limit of ultra-high-speed cutting of various materials is: aluminum alloy has exceeded 1600m/min, cast iron is 1500m/min, super heat-resistant nickel alloy is 300m/min, titanium alloy is 150~1000m/min, fiber-reinforced plastic is 2000~9000m/min. The cutting speed limit of various cutting processes is: turning 700~7000m/min, milling 700~7000m/min, and machining speed limit is: turning 700~7000m/min. 7000m/min, milling 300~6000m/min, drilling 200~1100m/min, grinding 250m/s or more, etc.
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 abrasives manufacturing skills, ultra-high-speed machining online active detection and control skills, etc.
Ultra-fine machining at that time refers to the dimensional accuracy of the machined parts is higher than 0.1μm, the appearance of the roughness Ra less than 025μm, as well as the machine tool positioning accuracy of the resolution and repeatability is higher than 0.01μm processing skills, also known as sub-micron processing skills, and is developing to nanometer-level processing skills.
Ultra-fine machining skills include: ultra-fine machining mechanism, ultra-fine machining equipment manufacturing skills, ultra-fine machining tools and sharpening skills, ultra-fine measurement skills and error compensation skills, ultra-fine machining task premise research.
