Ultra-high speed machining skills:
It is a modern machining skill that uses superhard material cutting tools to achieve material removal rate, machining accuracy and machining quality through extremely fast cutting and feed speed.
However, the cutting speed of ultra-high speed machining will be limited due to the workpiece material and different cutting methods. Not all methods are suitable for all materials.
The data shows that the cutting speed of different materials is also different (refer to the record in 2020)
Aluminum alloy has exceeded 1600 m/min, cast iron has reached 1500 m/min, ultra-heat-resistant nickel alloy has reached 300 m/min, titanium alloy has reached 150~1000 m/min, and fiber reinforced plastic has reached 2000~9000 m/min;
The cutting speed of various cutting processes is limited to:
Turning 700~7000m/min, milling 300~6000m/min, drilling 200~1100m/min, grinding above 250m/s, 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 abrasive tools manufacturing skills, ultra-high speed machining online active detection and control skills, etc.

Ultrafine processing:
The dimensional accuracy of machined parts is higher than 0.1 μ m. Appearance roughness Ra is less than 025 μ M and the resolution and repeatability of the positioning accuracy of the machine tool used are higher than 0.01 μ M's processing skills, also known as sub-micron processing skills, are developing towards nanometer processing skills.
Superfine processing skills mainly include: research on the mechanism of ultra-fine processing, research on the equipment manufacturing skills of ultra-fine processing, research on the skills of ultra-fine processing and sharpening, research on ultra-fine measurement skills and error compensation skills, and research on the premise of ultra-fine processing tasks.
