Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in figure 1, the utility model provides a novel hard and brittle grinding and polishing tool, which comprises a base 1, wherein a polishing block 2 is arranged on the lower surface of the base 1, the projection of the polishing block 2 in a vertical plane is inverted trapezoid, a first included angle a between the waist of the trapezoid far away from the center of a grinding disc and the lower bottom is 45-60 degrees, a second included angle b between the waist of the trapezoid near the center of the grinding disc and the lower bottom is 65-85 degrees, the utility model has the advantages that the projection of the polishing block 2 in the vertical plane is inverted trapezoid, the waist of the trapezoid far away from the center of the grinding disc is positioned at the outer end of the polishing block 2, the first included angle is 45-60 degrees, edge breakage caused by vibration of the grinding disc beyond the edge of a quartz stone plate can be effectively avoided, the plate surface scratch is influenced, the waist of the trapezoid near the center of the grinding disc is positioned at the inner end of the polishing block 2, the second included angle is 65-85 degrees, and unnecessary, the reliability is high.

The first included angle a between the waist and the lower bottom of the trapezoid far away from the center of the grinding disc is 52-57 degrees, the effect is good, and the included angle is preferably 52 degrees, 55 degrees or 57 degrees.

The second included angle b between the waist close to the center of the grinding disc and the lower bottom of the trapezoid is 72-80 degrees, the effect is good, and the second included angle b is preferably 72 degrees, 77 degrees or 80 degrees.

The polishing block 2 front side be equipped with at least one recess 3 that prevents to skid, recess 3 distribute along 2 direction of height of polishing block, polishing block 2 prevents the hand and skids when the installation.

The rear side surface of the polishing block 2 is also provided with a groove 3, so that the anti-skidding effect is good.

The number of the grooves 3 is two, and the effect is good.

The polishing block 2 is cast, cured and molded, has high strength, and the polishing block 2 is uniformly stirred, cast, cured and molded by a magnesium oxide bonding agent, a silicon carbide abrasive and other auxiliary materials, and achieves a high-definition mirror grinding effect of 50-80 degrees after grinding and polishing artificial synthetic quartz stone.
