What is the milling cutter?
A milling cutter is a rotary tool with one or more teeth for milling.
Common materials for milling cutters
1) High speed tool steel (referred to as high speed steel.)
2) Cemented carbide: It is made of metal carbide, tungsten carbide, titanium carbide and cobalt-based metal binder by powder metallurgy.
Common cemented carbides can generally be in three categories:
1. YG cemented carbide
Commonly used grades YG3, YG6, YG8.
2. YT cemented carbide
Commonly used grades are YT5, YT15, and YT30.
3. General purpose cemented carbide
An appropriate amount of rare metal carbides such as tantalum carbide and tantalum carbide are added to the above two types of cemented carbides.
