Unlike other metal materials, the biggest problem is that the rubber will cause the porous of the grinding wheel to block. Once the porous are blocked, the grinding temperature will increase.
In addition to the loss of the cutting force of the grinding wheel, the surface of the rubber will also dissolve, and further cause undesirable conditions such as uneven surface, burrs and even cracks.
Rubber grinding problem
Since the main purpose of the rubber roller is to support the iron, paper, and the like. If the surface is not flat, the products produced are not easy to smooth, and mutual movements are prone to problems that are not smooth.
In order to solve this problem, we must enlarge the pores of the grinding wheel as much as possible. However, in general, if the pores are enlarged, the amount of the bonding agent of the grinding wheel is small, and the bonding strength is weakened, which may cause the grinding wheel to be easily broken. It is easy to block the background with high grinding temperature and strengthens the risk of grinding wheel rupture.
In addition, if you want to maintain the same pores, it is "not easy to choose fine-grained abrasives." Because the abrasive particles are fine, the volume of the abrasive is small, the area where the bonding agent is fixed is easily insufficient, and if the atmospheric pores are added, the amount of the bonding agent is not enough. As a result, the structure of the grinding wheel is more fragile.
Therefore, most atmospheric or multi-porous grinding wheels have no way to use fine-grained abrasives. In this way, when you want to pursue a more detailed surface, you need to add a polishing process. Not only is time consuming, but also difficult to process.
Grinding wheel designed for rubber
After years of trial and error, using unique pore and binder technology, we can separate the pores from the binder. In this way, the problem that the structure is not strong enough can be solved.
However, even if the pores can be independent, if the dispersion is not uniform, the wheel may still be in danger of rupture due to uneven tissue. Therefore, after repeated trials and repeated trials, we finally succeeded in solving the problem of uniform pores.
With this breakthrough, we can not only adjust the size of the pores as much as we want, without worrying about cracking. Even the atmospheric hole grinding wheel can be matched with fine-grained abrasives (currently #400 or more). In this way, a finer rubber roller surface can be machined.
