According to the shape classification of tungsten steel milling cutters, there are two types: standard cutters and non-standard cutters. Below, Xinyongde's editor will explain in detail to everyone.


1. It can be divided into standard knives, with a general diameter of (1-20mm). Tungsten steel 4-blade, 2-blade milling cutter, tungsten steel ball cutter, tungsten steel round nose milling cutter.


2. Non standard knives, with varying diameters and strange shapes, have a wide variety of types, such as tungsten steel small diameter flat knives, deep groove knives, etc.


Tungsten steel milling cutters are classified according to the machining particles of the cutters: ultrafine tungsten steel milling cutters, ultrafine tungsten steel milling cutters, and ultrafine tungsten steel milling cutters;


The hardness of milling cutters produced by different particles varies.


According to grain size, hard alloys can be divided into ordinary hard alloys, fine-grained hard alloys, and ultrafine grained hard alloys.


According to the main chemical composition, hard alloys can be divided into tungsten carbide based hard alloys and titanium carbide based hard alloys. Tungsten carbide based cemented carbides include Tungsten Cobalt (YG), Tungsten Cobalt Titanium (YT) and Rare Carbides (YW). They have their own advantages and disadvantages. The main components are Tungsten Carbide (WC), Titanium Carbide (Tic), niobium carbide (NbC) and other commonly used metal bonding phases are Co.


Titanium carbide based hard alloy is a hard alloy mainly composed of Tic, commonly used as metal bonding phases Mo and Ni.


Tungsten steel milling cutters, hard alloy cutting tools (especially indexable hard alloy cutting tools) are the leading products of CNC machining tools. In some countries, over 90% of turning tools and over 55% of milling cutters are made of hard alloy, and this trend is still increasing. Since the 1980s, the CNC tungsten steel milling cutter industry has continuously expanded the production of various integral and indexable hard alloy cutting tools or blades, and their varieties have expanded to various cutting tool fields. Among them, indexable hard alloy cutting tools have expanded from simple turning and surface milling cutters to various precision, complex, and formed tool fields. Hard alloy is also a commonly used material for manufacturing general cutting tools such as drill bits and surface milling cutters. At the same time, the use of hard alloys for complex cutting tools such as reamers, end mills, medium and large modulus gear cutting tools, and broaches is also increasing. The annual output value of hard alloy cutting tools and blades has accounted for over 30% of the total output value of cutting tools.
