We all know that cemented carbide is an alloy material made by powder metallurgy process and bonded metals. One or more alloys composed of bonded metal diamonds are often called cemented carbide. With the progress of science，technology and the development of production, many cemented carbide workpieces need to be finish process,which has high requirements for tolerance size and surface roughness. Today Zhuzhou Chuangrui Cemented Carbide Co., Ltd. will take you to learn what is cemented carbide precision machining?
1, Cutting is a type of carbide precision machining. Cutting is one of the commonly used ways of cutting carbide bars, plates and wires, and for grooving or cutting below 1mm, diamond ultra-thin cutting discs are commonly used for processing
2, Diamond resin matrix type cutting disc, in which the outer ring belt is the resin bond abrasive working layer, and the center part is made of high-strength and high-rigidity metal material, which is mostly used for grooving and cutting with medium and large depth of cut
3, Turning is the most common machining method for precision machining of cemented carbide. In the process of turning cemented carbide parts, the tool hardness must be higher than the workpiece hardness, so the tool materials for turning cemented carbide parts are mainly high-hardness and high-heat-resistant non-metallic adhesives CBN and PCD.
（1）For cemented carbide parts with hardness less than HRA90, choose BNK30 CBN cutter for large margin turning, and the tool will not be broken or burned. For cemented carbide parts with hardness more than HRA90, CDW025 PCD tools or resin-bonded diamond grinding wheels are generally used for grinding.
（2） Groove above R3 for precision parts machining of cemented carbide, for large machining allowances, it is generally rough with BNK30 material CBN cutters first, and then grinding with grinding wheels. For those with a small machining allowance, grinding can be carried out directly with a grinding wheel, or profiling with PCD tools.
For the milling process of tungsten carbide parts, according to customer needs, CVD diamond coating milling cutter and diamond insert milling cutter can be provided for precision parts processing, which can replace electrolytic corrosion and EDM processes, improve production efficiency, and product quality.
There are many processing methods for cemented carbide precision machining, such as EDM, slow wire cutting, CNC milling, CNC lathe machining, etc. Zhuzhou Chuangrui Cemented Carbide Co., Ltd. has 410 sets (sets) of advanced production and processing equipment such as turning and milling compound machining center, five-axis machining center, four-axis vertical machining center, CNC horizontal boring and milling machine, deep hole drilling and boring honing processing, vacuum sintering furnace, wire cutting, etc., and has the machining capacity of complex structural parts. It has very strong strength in cemented carbide precision machining, equipped with all kinds of advanced processing equipment, suitable for the processing of all kinds of high-precision, special materials, eccentric inner shape, elbows, and complex geometric parts.
