Description

Polishing grinding wheel

Technical Field

The utility model relates to a superhard materials instrument field, in particular to burnishing wheel.

Background

With the rapid development of modern science and technology, the requirements on materials are higher and higher. Some new materials with excellent properties have been developed, but many of these materials are hard and brittle materials and are often inconvenient to post-process. And in order to make products have excellent performance, the dimensional accuracy of devices made of the materials is gradually improved, and high-accuracy surface grinding is required. The grinding wheel made of the diamond material has high hardness, small friction coefficient, easy outflow of cutting scraps and quite excellent heat conduction performance, so that the processing surface roughness is small, and the high-precision grinding processing of hard and brittle materials can be realized.

The grinding wheel of superhard material for polishing the surface of a workpiece adopts a method of increasing the contact area with the workpiece in order to better grind the workpiece and improve the flatness of the processed workpiece, thus leading to a polishing grinding wheel with larger ring width and presenting a continuous circular ring shape in the overall shape. However, the ring bit with an excessively large ring width is difficult to be directly pressed, molded, sintered and trimmed, and the polishing grinding wheel is usually prepared by a method of firstly preparing a fan-shaped grinding wheel block and then splicing the fan-shaped grinding wheel block into a whole ring. However, the design has the potential safety hazard, because the grinding wheel block is only bonded with the adjacent grinding wheel block and the lower matrix through the adhesive, under the high-speed rotation of the grinding wheel, the grinding wheel block has the tendency of falling outwards due to the centripetal force. If the bonding is not firm and the grinding wheel is aged, the grinding wheel block is easy to fly out to hurt people or damage equipment.
