What are the processing technologies for precision mechanical parts?
11-02 / 2020

Ultra high speed machining skills refer to modern machining skills that use cutting tools with superhard materials and greatly improve cutting speed and feed speed to improve data cutting rate, machining accuracy, and machining quality.






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






The cutting speed limitations of various cutting processes are: turning 700-700m/min, milling 300-6000m/min, drilling 200-1100m/min, grinding above 250m/s.






The skills of ultra-high speed machining mainly include: research on ultra-high speed cutting and grinding mechanisms, manufacturing skills of ultra-high speed spindle units, manufacturing skills of ultra-high speed feed units, manufacturing skills of ultra-high speed machining tools and grinding tools, and online active inspection and control skills of ultra-high speed machining.






Ultra precision machining at that time referred to the dimensional accuracy of the processed parts being higher than 0.1 μ m. Outer 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 level processing skills, are being developed towards nanometer level processing skills.






The skills of ultra fine machining mainly include: research on the mechanism of ultra fine machining, research on equipment manufacturing skills of ultra fine machining, research on ultra fine machining skills and blade grinding skills, research on ultra fine measurement skills and error compensation skills, and research on the premise of ultra fine machining tasks.
