Cemented carbide die is a kind of alloy material made involving hard compound of refractory steel and binding metal by powder metallurgy process. The hardness of cemented carbide is extremely high, so pay attention towards method when polishing this cemented carbide die. lThe polish in the powder metallurgy mould lThe polish from the tungsten carbide die in addition to carbide punch dies The polish on the powder metallurgy mould There is still an array of polishing methods for powder snow metallurgy molds by normal operation. The main applications used are brush, track, scraper, etc. However, guide book operation has two problems, one is that the caliber of polishing is difficult to control, judging by the functioning experience, the other is always that the production efficiency is not really high, only one product can be processed at the same time, the labor intensity is usually large, the production fee is high, it is difficult to realize large-scale production. In addition to manual polishing, there is mechanical polishing, which is far more convenient than manual polishing. YOU. Powder metallurgy die polishing by way of rolling mill The rotating brush drives the workpiece for you to rotate. During the moving process, the brush loads the burrs about the workpiece and makes that burrs fall off, in order to achieve the purpose regarding polishing the powder metallurgy mould. Reasonable selection of wash material and rotation speed and also other parameters, can be ready-made with different powder metallurgy perish. 2. Polish with concluding machine Finishing machine is principally divided into vibration concluding machine, centrifugal light adornment machine, magnetic light decoration machine, flow finishing machine, roller light decoration machines, which vibration finishing equipment, roller light decoration machine has been widely used in natural powder metallurgy die polishing sector. 3. Sand blasting polishing Sand blasting is usually to use compressed air as being the power to form any high-speed jet beam, the high-speed jet on the powder metallurgy mold that they are treated, the use of abrasive impact on the powder metallurgy form surface and cutting activity, so that the surface from the carbide die to get yourself a certain degree of cleanliness and different roughness, upskill the mechanical properties on the carbide die surface. FOUR. Heat polishing The principle could be that the powder metallurgy mould to get polished is placed in a very sealed container with sufficient strength, and then fed proper certain proportion of pre-mixed combustible fuel, which is ignited with the spark plug to produce an instant high temperature to remove the burrs to the carbide die surface. The polishing effect on this method is good, it's going to not affect the group of parts, it is applicable to a number of, but the cost can be relatively high. The polish with the tungsten carbide die along with carbide punch dies JUST ONE. Chemical polishing The convex part associated with tungsten carbide die and carbide punch die in the chemical method can be dissolved ahead of obtain a smooth area. Complex shapes can end up being polished without complex tools, and many pieces can be polished together. 2. Electrolytic polishing The identical basic principle as inorganic polishing, by the selective dissolution of the tungsten carbide die in addition to carbide punch die surface in the small projections, smooth this surface. Compared with substance polishing, the cathode reaction is often eliminated and the effect is much better. 3. Ultrasonic polishing The carbide die is place in the abrasive suspension and put into the ultrasonic field along, and the abrasive will be ground and polished within the surface of the carbide die by vibration of the ultrasonic influx. This method will not cause deformation from the cemented carbide, but it's difficult to manufacture in addition to install tooling. 4. Substance polishing Fluid polishing is driven by hydraulic stress, so that the fruit juice medium carrying abrasive particles flows forward and backward across the surface with the carbide die at top speed to achieve the reason for polishing. 5. Magnetic grinding and polishing Magnetic abrasives are employed to form abrasive brushes under the action of your magnetic field to grind the tungsten carbide pass away and carbide punch cease to live. The mold determines the forming of a part. For the accuracy with the part, the polishing of the carbide die is very important. https://www.burraycarbide.com/Carbide-Dies-Moulds-pl3208743.html 201911ld
