Cemented carbide die is a strong alloy material made regarding hard compound of refractory metallic and binding metal by way of powder metallurgy process. The hardness of cemented carbide can be quite high, so pay attention for the method when polishing the particular cemented carbide die.

 There is still a wide range of polishing methods for natural powder metallurgy molds by guide book operation. The main applications used are brush, file, scraper, etc. However, guide operation has two down sides, one is that the quality of polishing is difficult to control, judging by the functioning experience, the other is the production efficiency is not necessarily high, only one product can be processed at a time, the labor intensity can be large, the production charge is high, it is difficult to realize large-scale production.

In addition to manual polishing, there is also mechanical polishing, which is more convenient than manual polishing.

YOU. Powder metallurgy die polishing by way of rolling mill

 The twisting brush drives the workpiece that will rotate. During the coming process, the brush loads the burrs to the workpiece and makes the actual burrs fall off, in an attempt to achieve the purpose associated with polishing the powder metallurgy mould. Reasonable selection of remember to brush material and rotation speed along with parameters, can be ready-made with different powder metallurgy expire.

2. Polish with polishing off machine

 Finishing machine is mainly divided into vibration finish machine, centrifugal light adornment machine, magnetic light beautification machine, flow finishing machines, roller light decoration appliance, which vibration finishing device, roller light decoration machine is widely used in natural powder metallurgy die polishing market.

3. Sand blasting polishing

 Sand blasting is usually to use compressed air since the power to form a new high-speed jet beam, the high-speed jet into the powder metallurgy mold for being treated, the use of abrasive affect the powder metallurgy style surface and cutting steps, so that the surface on the carbide die to get a certain degree of cleanliness and different roughness, to further improve the mechanical properties with the carbide die surface.

SOME. Heat polishing

 The principle is the powder metallurgy mould being polished is placed in a very sealed container with satisfactory strength, and then fed right into a certain proportion of pre-mixed combustible propane, which is ignited because of the spark plug to produce an instant high temperature to remove the burrs for the carbide die surface. The polishing effect of the method is good, it is going to not affect the organization of parts, it is applicable to a number of, but the cost is definitely relatively high.

The polish from the tungsten carbide die along with carbide punch dies

 ONE. Chemical polishing

 The convex part of tungsten carbide die and carbide hand techinque die in the chemical moderate can be dissolved before it uses obtain a smooth outside. Complex shapes can often be polished without complex tools, and many pieces can be polished as well.

2. Electrolytic polishing

 Identical basic principle as inorganic polishing, by the selective dissolution on the tungsten carbide die as well as carbide punch die surface with the small projections, smooth your surface. Compared with element polishing, the cathode reaction is usually eliminated and the effect is much better.

3. Ultrasonic polishing

 The carbide die is put in the abrasive suspension and put in the ultrasonic field together, and the abrasive is usually ground and polished around the surface of the carbide die with the vibration of the ultrasonic wave. This method will not cause deformation in the cemented carbide, but it's difficult to manufacture along with install tooling.

4. Liquid polishing

 Fluid polishing is definitely driven by hydraulic demand, so that the the liquid medium carrying abrasive particles flows back and forth across the surface in the carbide die at broadband to achieve the goal of polishing.

5. Magnetic mincing and polishing

 Magnetic abrasives are employed to form abrasive brushes under the action of an magnetic field to grind the tungsten carbide pass away and carbide punch stop functioning.

The mold determines the forming of a part. For the accuracy belonging to the part, the polishing of the carbide die is vital.
