Carbide End mills for aluminum tools are prone to burns and cracks on the surface after sharpening, which seriously affects the performance of the tool and its tool life. For this reason, we have found through production practice that the selection of grinding wheels with large particle size and large linear speed can truly and effectively avoid cracks and burns on the surface of Carbide End mills for aluminum tools, and ensure the improvement of sharpening quality. Let's take a look at the classification and use of cemented carbide with Xiaobian.

1. Classification, composition and use of commonly used cemented carbides
The cemented carbides produced in my country are divided into two categories: YT and YG. YT type is composed of titanium carbide, tungsten carbide and cobalt, etc. The main components are WC, TiC and Co, and are mostly used to make tools for cutting steel. Carbide End mills for aluminum manufacturers tell you that YG is an alloy of tungsten carbide and cobalt, and the main components are WC and Co. They are mostly used in the manufacture of tools for cutting cast iron, hardened steel, stainless steel, etc., as well as in the manufacture of various cemented carbide measuring tools. , molds, mining tools for geological mining and oil drilling, etc. In addition, there are also YW-type titanium-tungsten-cobalt-type cemented carbides with a small amount of precious metal carbides such as tantalum carbide or niobium carbide, which are used as tools for cutting special heat-resistant alloy materials.
2. Carbide for various tools
Another classification method is to divide various cemented carbides used for cutting, mining and other purposes into two categories: cermet cemented carbides and steel-bonded cemented carbides.
(1) Cermet cemented carbide is a powder metallurgy material formed by mixing refractory metal carbide powder (such as WC, TiC, etc.) with a binder (such as Co, Ni, etc.), pressure forming, and sintering. Such carbide tools are resistant to high temperature and wear, and are widely used in the manufacture of measuring tools and molds, as well as in the manufacture of drill bits and drill bits.
(2) Steel-bonded cemented carbide takes one or more carbides (such as TiC, WC, etc.) as the hardening phase, and uses the powder of alloy steel (such as high-speed steel, chrome-molybdenum steel, etc.) as the binder. , pressed and sintered powder metallurgy materials. Carbide End mills for aluminum manufacturers tell you that this is a new type of tool material, which can be divided into the following two types.
① The proportion of TiC in the high-speed steel-bonded cemented carbide is 35%, the mass proportion of high-speed steel is 65%, and the hardness after quenching-tempering is HRC69-73.
② The content of WC in the chromium-molybdenum steel-bonded cemented carbide is 50%, and the mass ratio of the chromium-molybdenum steel is 50%.
The above is the sharing of techniques for reducing the surface roughness of Carbide End mills for aluminum, I hope it will be helpful to everyone.
