Discussion on tungsten steel saw blade

Tungsten steel saw blade is cemented carbide saw blade. Tungsten steel saw blade is the most commonly used cutting tool in wood products processing. The quality of tungsten steel saw blade is closely related to the quality of processed products. Correct and reasonable selection of tungsten steel saw blade is of great significance for improving production and quality, shortening processing cycle and reducing processing cost.

Varieties, properties and characteristics of cemented carbide cutting tools

Cemented carbide tools (especially indexable cemented carbide tools) are the leading products of CNC machining tools. In some countries, more than 90% of turning tools and 55% of milling tools are made of cemented carbide, and this trend is increasing. Since the 1980s, the tool industry has expanded the consumption of all kinds of integral and indexable cemented carbide tools or inserts from time to time. The category of indexable cemented carbide tools has been extended to all kinds of cutting tools. The indexable cemented carbide tools have been expanded from simple turning tools and face milling tools to all kinds of fine, complex and forming tools. Cemented carbide is also a common material for making general cutting tools such as drills and face milling cutters. At the same time, the use of cemented carbide in reamers, end mills, medium and large modulus gear cutters and broaches is also increasing. At present, the annual output value of cemented carbide tools and inserts has accounted for more than 30% of the total output value of cutting tools. Varieties of cemented carbide cutting tools

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, as shown in Figure 3-19. Tungsten carbide based cemented carbides include tungsten cobalt (YG), tungsten cobalt titanium (YT) and rare carbide (YW). Each of them has its own advantages and disadvantages. The main components are tungsten carbide (WC), titanium carbide (TIC), niobium carbide (NBC) and so on. The common bonding phase is Co. Titanium carbide based cemented carbide is a kind of cemented carbide with tic as the main component, and the commonly used metal bonding phases are mo and Ni.
