    • juniperqq has written a new blog article "Adjusting the surface concentration of grinding wheel made in China" 12.20.2018

      Another method for adjusting the surface concentration of a grinding wheel made in China.

      Last time we talked about a method for adjusting the surface concentration of wheels, today says a simpler approach.

      Compared with the previous packing method, the other method of removing the filler is simple. The filler is made of spherical particles and the surface is smooth. The thickness of the metal bond is first deposited to be 20% of the height of the diamond abrasive grain (upper sand) and then used. The brush brushes off the filler and continues to deposit with the metal bond to the specified thickness.

      The method utilizes the effect that the metal binder has different particle holding capacities for different surface roughness and shape, and the disadvantage is that the particle size of the filler is equivalent to the size of the diamond abrasive particles, so that they are in the same plane after bonding, and are removed by mechanical methods. When filling, it is possible to brush off some of the diamond abrasives together, especially those with close-shaped shapes and smooth surfaces.

      The method of adjusting the concentration of the two kinds of the grinding wheel made in China has different advantages. Everyone needs to choose according to their own conditions.

So how do the free sample cutting disc do the protection work when they are used?
      There are many types of cutting discs. The cutting discs are not only different in shape and size, but also the abrasives, grain size, bonding agent, hardness and structure of the cutting discs are different. Thus, different cutting discs have different characteristics, and the cutting discs of different characteristics are adapted to different processing ranges. To achieve the desired grinding results, different cutting discs must be selected for different grinding situations.
      The safety protection of the cutting disc grinder is mainly the grinding wheel cover. Once the grinding wheel is broken, the wheel cover should have sufficient strength and reasonable structure to prevent the particles from flying, resulting in personal and equipment accidents.
      The wheel cover is usually welded with A3 steel plate and can also be made of cast copper. The protective cover of the smaller grinding wheel is also made of aluminum alloy. Cast iron is not suitable for use as a protective cover due to its low strength. The thickness of the cover wall should be reasonable, the thickness is too thin, the strength is not enough, and it is not safe when working; when it is too thick, it is cumbersome an

    • juniperqq has written a new blog article "Manufacturers talk about the correct way to choose cutting pieces" 11.22.2018

      When it comes to the cheap metal grinding disc, some people who know it must know more about it. According to the material, they are mainly divided into fiber resin grinding discs and diamond grinding discs. Then, what is the correct way to choose grinding discs? Do you know the following grinding wheel cutting disc manufacturers to talk to you?
      1. When to use: When we choose the cheap metal grinding disc, we should first choose the suitable one according to the occasion of the cutting disc. Because the performance requirements of the cutting disc are different for different use occasions, it is very important to choose the cutting piece reasonably. We have to choose the cutting piece according to the occasion we use, which can increase the safety factor, improve work efficiency and reduce our use cost.
      2. Selection of the cheap metal grinding disc of the ordinary cutting machine: The ordinary cutting machine usually refers to the cutting machine with fixed cutting table, power <3KW and rotation speed of 2900 rpm. The ordinary cutting machine usually cuts the workpiece with the diameter less than 50mm. Small cutting power In order to reduce the radial frictional resistance, we usually choose a grinding disc with a thickness of 3.2mm. The cutting piece is thinner and has a certain elasticity, and it will feel sharper when cutting.
      3. High-power cutting machine cheap metal grinding disc selection: High-power cutting machine usually uses the cutting power of more than 5.5KW, the rotating speed is 2800 rev/min, and the cutting workpiece has a large diameter. Because the torque is large during cutting, the cutting piece is damaged. It is also relatively large, so it will require a certain rigidity of the cheap metal grinding disc. Therefore, under normal circumstances, we will use a 3.8mm thick cutting piece.
