Date of issue：2020-06-09
Since it is precision, it must be the need for high-precision processing methods. For precision parts processing, there are many ways to process materials, some of which are known by many people, but there is one method that many people know but few people will use. This method is ultra-high speed precision parts processing. Let's take a look.
Ultra high speed machining technology is a very important part of precision parts processing technology, because precision machining needs high precision, and can only bear minimal error. Therefore, only in the machine equipment and materials to solve the problem, in improving the accuracy of processing at the same time, also will speed up.
It refers to the use of sharp props to improve the cutting speed, and enhance the cutting rate, object quality and processing accuracy of a technology.
This technology will change according to the material and cutting method. At present, it is generally considered that the cutting speed limit of various ultra-high speed cutting materials is: aluminum alloy over 1600m / min, cast iron 1500m / min, super heat resistant nickel alloy up to 300m / min, titanium alloy up to 150 ~ 1000m / min. Fiber reinforced plastic is 2000 ~ 9000m / min.
Superfinishing refers to the processing technology that the dimensional accuracy of the workpiece is greater than 0.1 μ m, the surface roughness Ra is less than 025 μ m, and the positioning accuracy resolution and repeatability of the machine tool are greater than 0.01 μ M. It is also known as submicron processing technology and is developing into nano processing technology.
