Some Techniques Of Grinding Wheel Dressing

Grinding wheel with the grinding process, will become blunt, so the use of the process to be constantly repaired, so that the wheel re-become sharp. The following describes how to better dress the wheel so that it maintains a higher grinding efficiency and quality.

Xiu Rui is a superhard abrasive grinding wheel abrasive grinding sharp processing. In this process, the need to remove the binder between the abrasive particles and grinding the grinding wheel abrasive, so that a very strong grinding performance of the abrasive grain abrasive protrusion, the formation of sharp cutting edge. Repair sharp must also be from the surface of the grinding wheel pores, remove the tiny material to prevent the grinding force on the grinding wheel increases, grinding wheel grinding force increases, will cause vibration and cause parts surface burns.

Without proper repair, even the best grinding wheels can not get high quality and dimensional consistency of machined parts. In fact, when you invest in high-quality grinding wheel, in order to obtain high grinding performance, it is very important to trim them well.

Shaping can be said to be part of the grinding wheel preparation work, it is the same time with ordinary grinding wheel sharpening. For the super-hard abrasive grinding wheel, the two processes are carried out separately, the first grinding wheel. In the use of super-hard abrasive grinding wheel, the plastic is used to create plastic tools or rollers, repair sharp is often a ceramic binder repair rod, after the completion of the plastic, the grinding wheel for sharp processing.

It is important to ensure that the spindle bearings are at a certain temperature, such as the usual grinding wheel grinding, before the grinding wheel includes shaping and repair. This avoids damage to the geometry of the part and the abnormal wear of the grinding wheel and dressing tool. The tool for dressing must be handled with care because it is usually made of hard, abrasionable but very brittle diamond material and is very sensitive to minor cracks and crushing due to minor collisions.

Because the diamond shaper itself is a tool, need to keep very sharp. The use of a blunt dressing tool to dress the wheel surface, will make the wheel blunt. In order to maintain a high quality and sharp diamond dressing tool, at regular intervals, 1/8 turns need to rotate the single or tapered dressing tool. The number of rotations can be determined according to the dressing situation, according to experience, at least once a day rotation. For chisel head and forming the dressing tool, it is generally necessary to rotate 180 ° before they are bluntly.

Most cylindrical grinders place parts and wheels on a horizontal line. The highest point of the outer circumference of the part and the highest point of the outer circumference of the grinding wheel is called the part / wheel contact point. The diamond dressing tool should adjust the grinding wheel as close as possible to the part / wheel contact point. It is more important to use a grinding wheel for internal grinding machines to trim the diamond dressing tool near the highest point of the outer circumference of the grinding wheel (ie, the part / grinding wheel contact point).
