Ultra-high-speed machining technology is an important part of precision machining technology, because precision machining requires high accuracy and small error standards, so it is necessary to work hard on machine tool processing and superhard materials to solve these problems. By improving the high-precision machining ability of machine tools, material cutting speed and so on can be solved.

So what is the ultra-high-speed machining technology? Let‘s take a closer look:

Ultra-high-speed machining technology refers to the use of super-hard materials for cutting tools, which greatly increases the cutting speed and feed rate to improve the data removal rate, machining accuracy and machining quality.

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

All kinds of cutting, the cutting speed of the process is limited to: turning 700~ 7000m/min, milling 300~ 6000m/min, drilling 200~ 1100m/min, grinding 250m/s or more, etc.

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

Precision parts processing Ultra-fine machining at that time referred to machining skills with a dimensional accuracy higher than 0.1 μm, a roughness Ra less than 0.25 μm, and a positioning accuracy higher than 0.01 μm, also known as sub-micron processing skills, and is being developed towards nano-scale processing skills.

Precision parts processing ultra-fine machining skills mainly include: the mechanism of ultra-fine machining, ultra-fine machining equipment manufacturing skills, ultra-fine machining and grinding skills, ultra-fine measurement skills and error compensation skills, and ultra-fine machining tasks.
