Several Dressing Diamond Grinding Wheel Coup

According to the size of diamond particles and their distribution in the pen, diamond pen is divided into chain, layer, row and powder and several. From the day with a strong combination of alloy as a binder, the use of diamond grinding wheel particles are not easy to fall off until the use of no need to midway grinding.

Rolling method

Rolling method to dress the diamond wheel, grinding wheel speed by 1 ~ 2m / s driven rolling wheel (made of metal, carbide or abrasive) rotation.

Roller wheel added to the grinding wheel about 3 ~ 5MPa pressure, the diamond grinding wheel surface of the abrasive particles or abrasive particles off. Rolling method of grinding wheel grinding performance is better, lower cost, but the workpiece surface roughness rough, rolling wheel easy to wear, short life, easy to lose precision. So this dressing method is mainly used for small batch, the precision is not high forming grinding.

The hardness of the grinding wheel is better, otherwise the grinding wheel will produce local shape distortion. Electroplated diamond grinding wheel defects: the coating metal and the matrix and the combination of the surface of the abrasive does not exist a strong combination of chemical metallurgy, abrasive is actually only mechanical embedded in the coating metal, and thus holding a small, diamond particles in the load In order to increase the holding force, it is necessary to increase the thickness of the coating. As a result, the abrasive wear height and the chip space are reduced, and the grinding wheel is liable to be clogged, and the abrasive grains are likely to be clogged, Poor heat dissipation, the workpiece surface prone to burns. At present, the domestic plating wheel manufacturing has not yet achieved according to the requirements of processing conditions and optimize the design of the best grinding wheel, monolithic electroplated diamond grinding wheel of these inherent drawbacks will greatly limit its application in efficient grinding.

In recent years, with the rapid development of high-speed grinding and ultra-precision grinding technology, the grinding wheel put forward higher requirements, ceramic and resin binder grinding wheel has been unable to meet the needs of production, metal bonding wheel due to its bonding strength High, good shape, long service life and other significant features in the production has been widely used. Metal bonding agent Diamond grinding wheel according to the different ways to have a variety of sintering and plating two types. In order to give full play to the role of superhard abrasive, foreign from the early 1990s began to use high-temperature brazing process to develop a new type of grinding wheel, that is, single-layer high-temperature brazing super-hard abrasive grinding wheel, the current domestic grinding wheel is still in the development stage.
