Grinding Wheel Dressing Secret

The key factors to improve grinding wheel grinding performance are good dressing tools and proficient dressing techniques. Actually, a high-quality dressing tool and a proficient operator can maintain high grinding performance of a grinding wheel. This is very important because a factory is not capable of equip specialized grinding wheels for each worker's situation.

Dressing is a processing that turn superhard grinding wheel abrasive grains sharper, during which the bonding agent and blunt abrasive grains should be removed so as to form strong grinding performance and a sharp cutting edge. Dressing should start from the pores on grinding wheel surface, remove tiny materials to protect grinding wheel from increased grinding force to cause vibration and parts surface burn.

If no proper dressing is processed, even if the best grinding wheel cannot achieve workpiece high quality and size uniformity. Dressing is a part of grinding wheel preparation work, which can proceed with ordinary grinding wheel dressing. For superhard abrasives grains grinding wheel, the two processes are divided. First grinding wheel dressing with dressing tools or roller. Dressing usually use a ceramic-bonded dressing rod.

Before dressing grinding wheel, it is very important to guarantee the spindle bearings in certain temperatures. For this can avoid damage parts geometric shape and abnormal wear of grinding wheel dressing tools. We have to be careful with dressing tools in that they are usually made up of hard, wearing-resisting and brittle diamond materials, which are sensitive to tiny cracks and breakage.

Since diamond dresser itself is a cutting tool, so it should be sharp. If we use a dulling dressing tool to trim grinding wheel surface, it will turn dull. To maintain a high-quality and sharp diamond dressing tool, twirling1/8 single point or finishing tool with a cone tip is needed at regular intervals. Rotating times can be based on dressing situation. Usually rotating once a day at least. For chisel head and dressing tools, generally they need 180 rotating before dull.
