Application of Tungsten Carbide Tool Inserts
(1) In the field of cutting tools
Cemented carbide still maintains excellent cutting performance at a high temperature of 800-1000°C. It is suitable for fast cutting at high temperatures and has practical significance for improving economic efficiency. Therefore, it is gradually replacing high-speed steel tools. In 2017, it has not only been widely used in turning tools, planers, boring cutters, three-sided cutting tools, mold milling cutters, end mills, etc., but also with the continuous promotion of intelligent manufacturing and Industry 4.0, the application prospects of cemented carbide tools are broader , Looking forward to the future, the tool material is undoubtedly the world of cemented carbide.
(2) In the field of mould
The drawing dies and drawing dies for all kinds of steel wires are basically cemented carbide. The progressive die for manufacturing zipper teeth is made of YG8 and YG15 cemented carbide to make large-diameter drawing dies, and YG20C cemented carbide is made of multi-station progressive. mold. Non-magnetic molds are generally made of YG15 and YG20 cemented carbide, and the service life of the wire drawing dies of YG8 treated by nitrogen ion implantation is more than doubled. In short, the application of cemented carbide in molds is becoming more and more common.
Cemented carbide tools, especially indexable cemented carbide tools, are the leading products of CNC machining tools. Since the 1980s, the variety of integral and indexable carbide tools or inserts has been expanded to various In the field of cutting tools, indexable carbide tools have expanded from simple turning tools and face milling tools to various precision, complex, and shaped tools.
⑴ Types of carbide tools
According to the main chemical composition, cemented carbide can be divided into tungsten carbide-based cemented carbide and titanium carbon (nitride) (TiC(N))-based cemented carbide.
Tungsten carbide-based cemented carbide includes three types: tungsten-cobalt (YG), tungsten-cobalt-titanium (YT), and rare carbide-added (YW). They have their own advantages and disadvantages. The main components are tungsten carbide (WC) and titanium carbide. (TiC), tantalum carbide (TaC), niobium carbide (NbC), etc. The commonly used metal bonding phase is Co.
Titanium carbon (nitride)-based cemented carbide is a cemented carbide with TiC as the main component (some of which are added with other carbides or nitrides). The commonly used metal bonding phases are Mo and Ni.
ISO (International Organization for Standardization) divides carbides for cutting into three categories:
K category, including K10 ~ K40, is equivalent to my country's YG category (main component is WC. Co).
P category, including P01 ~ P50, is equivalent to my country's YT category (main component is WC. TiC. Co).
Class M, including M10～M40, is equivalent to the YW class in my country (the main component is WC-TiC-TaC(NbC)-Co).
Each grade represents a series of alloys ranging from high hardness to maximum toughness with numbers between 01 and 50.
⑵ Performance characteristics of cemented carbide tools
The performance characteristics of cemented carbide tools are as follows:
①High hardness: Cemented carbide tools are made of carbide (called hard phase) with high hardness and melting point and metal binder (called bonding phase) through powder metallurgy, and its hardness reaches 89～93HRA , Much higher than high-speed steel, at 5400C, the hardness can still reach 82-87HRA, which is the same as the hardness of high-speed steel at room temperature (83-86HRA). The hardness value of cemented carbide varies with the nature, quantity, particle size and content of the metal bonding phase of the carbide, and generally decreases with the increase of the content of the bonding metal phase. When the content of the binder phase is the same, the hardness of the YT alloy is higher than that of the YG alloy, and the alloy with TaC (NbC) added has higher high temperature hardness.
②Bending strength and toughness: The bending strength of commonly used cemented carbide is in the range of 900～1500MPa. The higher the metal bonding phase content, the higher the bending strength. When the binder content is the same, the strength of the YG-based (WC-Co) alloy is higher than that of the YT-based (WC-TiC-Co) alloy, and as the TiC content increases, the strength decreases. Cemented carbide is a brittle material, and its impact toughness at room temperature is only 1/30 to 1/8 of that of high-speed steel.
⑶ Application of commonly used carbide tools
YG alloys are mainly used for processing cast iron, non-ferrous metals and non-metallic materials. Fine-grained cemented carbide (such as YG3X, YG6X) has higher hardness and wear resistance than medium-grain when the cobalt content is the same. It is suitable for processing some special hard cast iron, austenitic stainless steel, heat-resistant alloy, Titanium alloy, hard bronze and wear-resistant insulating materials, etc.
The outstanding advantages of YT cemented carbide are high hardness, good heat resistance, higher hardness and compressive strength at high temperature than YG, and better oxidation resistance. Therefore, when the knife is required to have higher heat resistance and wear resistance, a brand with a higher TiC content should be selected. YT alloys are suitable for processing plastic materials such as steel, but not for processing titanium alloys and silicon aluminum alloys.
YW alloys have both the properties of YG and YT alloys and have good overall performance. It can be used for processing steel, but also for processing cast iron and non-ferrous metals. If the cobalt content of this kind of alloy is appropriately increased, the strength can be very high, and it can be used for rough machining and interrupted cutting of various difficult-to-machine materials.
