How to choose end mill flutes?
Why are carbide end mills categorized as single-flute, double-flute, 3-flute, 4-flute, 5-flute, and 6-flute? How should you make the choice?
?
The more flutes a carbide end mill has, the better its rigidity. lower cutting resistance, and higher efficiency. ?
?
With more flutes, there is less vibration and noise during cutting, leading to better product accuracy and surface quality after machining.
?
Carbide end mills with fewer flutes generally have a longer tool life.
?
However, this doesn't mean we should always choose carbide end mills with more flutes.
?
We should make our choices based on the material and the machining process.
?
For example, for high-hardness materials and high-precision machining, it's advisable to use multi-flute carbide end mills, while for easy-to-machine materials, it's better to opt for carbide end mills with fewer flutes.
