The key factors to the maximum to improve the grinding performance is good truing and dressing (commonly known as dressing) tools and skilled dressing technique. In fact, a high quality the dressing tool and master the skill of the operator wheel dressing, grinding wheel can always keep with high performance. And not just rely on the purchase of the so-called good grinding wheel. This is very important, because the shop not according to each operating situation, equipped with specialized grinding wheel.
Dressing is a superhard abrasive grinding wheel abrasive grinding process sharp. In this process, need to abrasive removal grinding wheel bond intergranular and blunt, the grinding wheel has the very strong grinding performance of grain binder, forming a cutting edge sharp. Dressing must also from the holes in the wheel surface, remove fine materials, increasing the grinding force act on the wheel to prevent the increase of grinding wheel, grinding force, will cause vibration and causing parts of the surface of burn.
Without the proper dressing, even the best grinding wheel is not likely to get high quality and consistency of the size of machined parts. In fact, when you invest in the wheel of high quality, in order to obtain high grinding performance, good finishing them is very important.
Plastic can be said to be a part of a grinding wheel preparations, it with ordinary grinding wheel dressing simultaneously. For super hard abrasive wheel, two processes are carried out separately, first of the shaping of the grinding wheel. In the use of super hard abrasive grinding wheel, plastic is the use of roller or shaping tool, dressing is often use a vitrified finishing rod in shaping after the completion of processing of grinding wheel dressing.
Before wheel truing and dressing including dressing, ensure the spindle bearing at a certain temperature (as is usually the grinding wheel state) is very important. This can avoid non normal wear damage parts of geometry and the grinding wheel and dressing tools. For the dressing tool used must be handled with care, because it is generally composed of hard, wear-resistant but also very brittle diamond material made from, and due to the slight collision, the force caused by micro crack and breakage are very sensitive.
