The CNC machining and cutting process is often accompanied by the generation of burrs, but when CNC machining stainless steel, why are there always many burrs?
To solve the above questions, the technicians simply shared their practical experience:
1. Stainless steel material factors:
Stainless steel may contain elements such as chromium, nickel, molybdenum, titanium, nitrogen, etc., which are relatively soft, and at the same time, the nickel element is high, so when cutting at high temperature, a sticky knife will occur, resulting in an increase in burrs.
2. Improve the tool:
The tool is not sharp enough, because tool wear has a great influence on the formation of burrs. When the tool wears to a certain extent, the arc of the tool tip increases. After the tool is used to a certain extent, the cutting edge can be updated; when machining precision parts, it is even more important to Use circular chamfers to reduce burrs. Under the same cutting conditions, diamond tools are more conducive to inhibiting burr formation than other tools.
3. Tool nose entry and exit sequence:
Not only the size of the burr in the exit direction of the tool is increased, but also the burr will be generated in the cutting direction of the tool;
4. Modify the milling parameters, increase the size of the feed rate and adjust the direction, etc.;
Burrs not only reduce the accuracy and quality of parts, but also affect the function of parts, and sometimes even lead to safety accidents. Dealing with burrs is a non-productive process, and improper removal can also lead to the scrapping of the entire product, resulting in financial losses.
If CNC machining stainless steel has a lot of burrs, can you try the solution from the experience shared above?
