What are the precision machining methods for mechanical parts ?

- Nov 21, 2019-

Nowadays, the use of precision CNC machining is still more in the industry, because it is a better processing method, which can meet the requirements of various CNC machining products, and it is more in line with people's requirements, so it makes people like it so much. 

What are the precision CNC machining parts manufacturing technologies ?

 

Ultra-high-speed machining skills refer to modern machining skills that use super-hard data cutting tools to improve data removal rate, machining accuracy and machining quality by greatly improving cutting speed and feed rate.

 

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

 

The cutting speed limits of various cutting processes are: turning 700~7000m/min, milling 300~6000m/min, drilling 200~1100m/min, grinding more than 250m/s and so on.


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

 

Ultra-fine machining means that the dimensional accuracy of the machined part is higher than 0.1μm, the appearance roughness Ra is less than 025μm, and the resolution of the machine tool positioning accuracy and the processing skill of repeatability higher than 0.01μm are also called sub-micron. Level processing skills and are working on nanoscale processing skills.

 

Superfine processing skills include: research on the mechanism of ultra-fine processing, equipment manufacturing skills research in ultra-fine processing, ultra-fine processing and sharpening skills research, ultra-fine measurement skills and error compensation skills, superfine processing tasks, premise discussion .
