Maximum grinding wheel can improve the performance of the key factors shaping and dressing is good (commonly known as dressing) tools and skilled finishing skills. In fact, a high-quality finishing grinding wheel dressing tools and techniques to master the operator can always maintain the grinding wheel with high performance. Rather than just relying on a good buy so-called wheel. This is important, because the plant is not operating conditions of each person, with a special grinding wheel.
Dressing is the super-hard abrasive grit grinding wheel of sharp process. In this process, the need to remove the bond between the abrasive and blunt abrasive grinding wheel, the wheel has a strong abrasive outstanding grinding performance bond, the formation of a sharp cutting edge. Dressing must be from the surface of the pores in the grinding wheel to remove small material, to prevent the effect on the grinding wheel on the grinding force increases, the grinding wheel on the grinding force increases, causing parts will cause vibration and surface burns.
Without proper dressing, even the best wheel and can not get high-quality machined parts and size consistency. In fact, when you invest in a high-quality grinding wheel, grinding in order to obtain high performance, well it is very important to trim them.
Plastic can be said that part of the preparation grinding wheel, grinding wheel with an ordinary dressing the same time. For the grinding wheel, the two processes are carried out separately, the first shaping of the wheel. Using the grinding wheel grinding, shaping is to use the plastic tool or wheel, often with a dressing of vitrified dressing stick, in the shaping is completed, processing of grinding wheel dressing.
Included in the plastic wheel dressing with dressing before, to ensure that the spindle bearings in a certain temperature (such as the grinding wheel is usually the state) is very important. This prevents damage to part geometry and wheel dressing tool and the non-normal wear and tear. For the dressing tool must be careful with, because it is generally hard, wear-resistant diamond but very brittle material, and due to minor collisions, the force caused by tiny cracks and broken are very sensitive.
Because diamond is itself a shaper tool, to be kept very sharp. Use a blunt tool to trim the dressing wheel surface grinding wheel will blunt. In order to maintain a high quality and sharp diamond dressing tools, intervals, need 1 / 8 point, or enclosure with a single rotation of the cone tip dressing tools. Trimming the number of rotations can decide, based on experience, at least once a day rotation. For the chisel head and forming the dressing tool, it generally takes before they blunt 180 ° to rotate once.
