Ultra-high-speed machining technology in precision mechanical parts processing is an important part of precision machining technology, because precision machining requires high accuracy and small error standards, so that it is necessary to work on machine tool processing and super-hard materials to solve these problems. By improving the machine tool's high precision machining capability, to solve the material cutting speed and so on. So what are the ultra-high speed machining skills? Let's look at the following in detail.
Ultra-high-speed machining skills are modern machining skills that use super-hard material cutting tools to improve the removal rate, machining accuracy and machining quality by greatly improving the cutting speed and feed rate.
The cutting speed limit 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 limits of various cutting processes are: 700~7000m/min for turning, 300~6000m/min for milling, 200~1100m/min for drilling, 250m/s or more for grinding, 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 tool and abrasive manufacturing skills, ultra-high-speed machining online active detection and control skills, etc.
Ultra-fine machining is 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.
