Why do CNC machining stainless steel always have a lot of burrs? ? ?

CNC machining is often accompanied by burrs, but when CNC machining stainless steel, why are there many burrs?

To solve the above questions, technicians simply shared their practical experience:

1. Stainless steel material factors:

The stainless steel material may contain chromium, nickel, molybdenum, titanium, nitrogen and other elements, which are relatively soft, and at the same time the nickel element is relatively high, so when high temperature cutting, sticky knives are generated, resulting in increased burrs.

2. Improve the tool:

The tool is not sharp enough, because the tool wear has a great influence on the formation of burrs. When the tool wears to a certain degree, the arc of the tip increases, and after the tool is used to a certain extent, the blade can be updated;

When machining precision parts, arc chamfering should be used to reduce burrs.

Under the same cutting conditions, diamond tools are more beneficial to suppress the formation of burrs than other tools.

3. The sequence of tool tip entry and exit:

Not only the size of the burr in the exit direction of the tool is increased, but also the type of burr will be generated in the direction of the tool;

4. Modify the milling processing parameters, increase the size of the feed rate and adjust the direction, etc.;

The burr not only reduces the accuracy and quality of the parts, but also affects the function of the parts, and sometimes even causes safety accidents. Dealing with burrs is a non-productive process. Improper removal will also lead to the scrap of the entire product, causing economic losses.
