Coated tool Introduction
Tool coating technology since the advent of the improvement of tool performance and processing technology plays a very important role in the coating technology will be coated with a layer of traditional film, the tool performance has undergone tremendous changes. The main coating materials are: Tic, TiN, Ti (C, N), TiALN, ALTiN and so on. Coating technology has been used in end mills, reamers, drill bits, composite hole machining tools, gear hobs, shaper shaper, shaving cutter, forming broach and various machine holder indexable inserts to meet high-speed machining Strength, high hardness cast iron (steel), forged steel, stainless steel, titanium alloy, nickel alloy, magnesium alloy, aluminum alloy, powder metallurgy, non-metallic materials such as the production of different requirements of the workpiece.

Thermal Spraying Technology in Remanufacturing Engineering
Thermal Spraying Technology in Remanufacturing Engineering The connotation of remanufacturing project: Remanufacturing project is the product life cycle theory as a guide to waste products to achieve leapfrog development as the goal, to high quality, high efficiency, energy saving, materials, environmental protection as a criterion to advanced technology and industrial production as a means to repair, Transformation of waste products, a series of technical measures or engineering activities in general. The research object of equipment remanufacturing project – "product" is generalized. It can be either a device, a system, a facility, or a component thereof, both hardware and software. In short, remanufacturing is the industrialization of high-tech maintenance of used products. The cost of the product from the demonstration, design, manufacture, use, maintenance, until the scrapped is called the full life cycle cost. Traditional concepts tend to focus on 20% -30% of the total life cycle cost of the product before the half (demonstration, design, manufacturing stage) investment, but ignored the total life cycle cost of 70% -80% of the product after the second half ( Use, repair, scrap stage) investment. Remanufacturing project is to the latter part of the product for the research object, to enhance the transformation of...
Cemented Carbide
Hard knives are the leading products of CNC machining tools. In some countries, more than 90% of the turning tools and more than 55% of the milling tools are made of carbide, and this trend is increasing. Carbide can be divided into ordinary hard alloy, fine grain cemented carbide and supercrystalline cemented carbide. According to the chemical composition of distinction, can be divided into tungsten carbide-based carbide and carbon (nitrogen) titanium-based cemented carbide.
How to determine the proportion of tantalum and niobium(二)
Such as the weight of the replacement, then the equivalent of the original design of the brand to increase the content of tantalum, leaving the alloy brittle, which is widely believed that niobium tantalum alloy brittle reasons. Because of this, I have done a lot of experiments, and in practice the application that, with niobium tantalum, the total number of TaC + NbC to the original design of the number of molecules in the TaC 1.2 to 1.25 times The best, and the content of tantalum must meet the alloy in the hard phase of the single molecule surrounded by more than in order to give full play to the comprehensive advantages of tantalum and niobium. Otherwise, it will form an alloy structure imbalance and affect its effect. In this way, due to the increase in the overall number of molecules of TaC + NbC, and the presence of some TaC, it is a good way to make up for some of the deficiencies of light using NbC. In addition, since the TaC + NbC is reduced by the weight percentage when TaC is used only, the percentage of WC is increased, and the wettability of the cobalt is enhanced...
High speed steel cutting tools
High speed steel is a high alloy steel that joins more alloy elements such as W, Mo, Cr and V. High-speed steel cutting tools in the strength, toughness and process, and so has a good overall performance in complex tools, especially the manufacture of hole processing tools, milling cutter thread cutter, broach, cutting tool and other blade-like complex tool, Occupy the main position.

Arc spraying mold molding process
⑤ fill the substrate: When the spray coating to form the shell, the use of matrix material filled with real, the shell for support and reinforcement. The choice of matrix material, mainly based on the working conditions of the mold and the spray layer of different materials, choose different materials and processes. Mold on the substrate material requirements, should have a certain strength, to meet the working condition of the mold force requirements, easy to shape. As the spray shell is formed, its shape is more complex, the matrix shape must be closely matched with the coating, therefore, the filling matrix must have the characteristics of easy forming, to have a certain degree of thermal conductivity and heat resistance, while its thermal conductivity and thermal expansion Coefficient should be similar to the metal spray coating, especially when the mold temperature is high, it should be noted.
