Tungsten steel milling cutter is a kind of tool made of tungsten steel (carbide, also called tungsten titanium alloy). Generally it is mainly used in CNC machining center, CNC engraving machine. It can also be mounted to the ordinary milling machine to process some relatively hard and uncomplicated heat treatment materials, tungsten steel milling cutters are widely used, using high-speed processing. The hardness of tungsten steel milling cutter is Vickers 10K, second only to diamond. Because of this, tungsten steel milling cutters have the characteristic of not being easily worn, and are brittle and hard, not afraid of annealing.


According to the shape of the cutter classification. 1. Can be divided into standard cutters, generally with a diameter of (1 - 20mm). Tungsten steel 4 flute, 2 flute milling cutter, tungsten steel ball cutter, tungsten steel round nose milling cutter.


2. Non-standard knives, variable diameter, strange shape, a wide variety, such as tungsten steel small diameter flat knives, deep groove knives, etc.

Classified according to the processing particles of the cutter.


Super fine grain tungsten steel milling cutter, very fine grain tungsten steel milling cutter, very fine super fine grain tungsten steel milling cutter; the hardness of the milling cutter processed by different grains is different.

non-standard tool

Features


Carbide tools (especially indexable carbide tools) are the leading products of CNC machining tools, some countries have more than 90% of turning tools, more than 55% of milling tools are made of carbide, and this trend is still increasing. since the 1980s, the tool industry has been expanding the production of various integral and indexable carbide tools or inserts, and their varieties have been extended to various cutting tools, with indexable carbide tools expanding from simple turning tools and face mills to a variety of precision, complex, and forming tools. Cemented carbide is also a common material used in the manufacture of general-purpose tools such as drills and face mills. At the same time, the use of carbide for complex tools such as reamers, end mills, medium and large modulus gear tools for machining hardened surfaces, broaches, etc. is also increasing. The annual output value of cemented carbide tools and inserts has accounted for more than 30% of the total output value of cutting tools.


Types


According to the grain size distinction, cemented carbide can be divided into ordinary cemented carbide, fine grain cemented carbide and ultra-fine grain cemented carbide. According to the main chemical composition, cemented carbide can be divided into tungsten carbide-based cemented carbide and titanium carbide-based cemented carbide. Tungsten carbide includes tungsten-cobalt (YG), tungsten-cobalt-titanium (YT) and rare carbide (YW), which have their own advantages and disadvantages, the main components are tungsten carbide (WC), titanium carbide (Tic), niobium carbide (NbC), etc. The commonly used metal bonding phase is Co. titanium carbide carbide is a tungsten carbide with Tic as the main component, and the commonly used metal bonding phases are Mo and Ni.
