It can be divided into standard knives with a general diameter of (1-20,). Tungsten steel 4-edge, 2-edge milling cutter, tungsten steel ball cutter, tungsten steel round nose milling cutter.
2. Nonstandard Dao, with variable diameter, strange shape and various types.
Material characteristics of high wear resistant milling cutter
Cemented carbide tools (indexable carbide tools) are the leading products of CNC machining tools. More than 90% of turning tools and 55% of milling cutters are made of cemented carbide, and this trend is increasing. Since the 1980s, the tool industry has been expanding the production of all kinds of integral and indexable cemented carbide tools or inserts, and their varieties have been extended to various cutting tool fields. Among them, indexable cemented carbide tools have expanded from simple turning tools and face milling cutters to various precision, complex and forming cutting tools. Cemented carbide is also a common material for making drill bits and face milling cutters. At the same time, the use of cemented carbide for reamers, end mills, medium and large modulus gear cutters, Broaches and other complex tools 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 of high wear resistant milling cutter materials
According to the grain size, 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 based cemented carbide includes tungsten cobalt (YG), tungsten cobalt titanium (YT) and rare carbide (YW). Each of them has its own advantages and disadvantages. The main component is tungsten carbide (WC), titanium carbide (TIC), niobium carbide (NBC). The common metal bonding phase is Co. Titanium carbide based cemented carbide is a kind of cemented carbide with tic as the main component. The commonly used metal bonding phases are mo and Ni.
High wear resistant milling cutter length
Divided into standard and extended. Generally, the same diameter of the lengthening knife is more expensive than the standard length.
Cemented carbide milling cutter is mainly divided into: integral cemented carbide milling cutter, carbide straight shank groove milling cutter, carbide saw blade milling cutter, cemented carbide spiral drill milling cutter and carbide machine reamer milling cutter.
