Combined type brazing ultrahard abrasive grinding wheel matrix suitable for ultrahigh-speed grinding

Abstract

The invention discloses a combined type brazing ultrahard abrasive grinding wheel matrix suitable for ultrahigh-speed grinding. The combined type brazing ultrahard abrasive grinding wheel matrix provided by the invention comprises a bottom plate, a fixing ring, a pressing ring, a cover plate and embedded lumps, wherein the outer side wall of the annular groove is uniformly provided with multiple installation grooves along the circumference of the bottom plate; one embedded lump which is integral in a T shape is arranged in each installation groove; the fixing ring is arranged in the annular ring in a matching mode and mutually connected with the bottom plate, and the fixing ring is used for limiting the multiple embedded lumps; a pushing mechanism for propping the embedded lumps against the outer side wall of the annular groove is connected to the fixing ring corresponding to each embedded lump; the pressing ring is covered above all the embedded lumps and mutually connected with the bottom plate, and the pressing ring is used for pressing the embedded lumps; the cover plate is arranged in the central circular opening of the pressing ring in a matching mode and connected to the bottom plate; and a part of the cover plate is covered on the fixing ring. The combined type brazing ultrahard abrasive grinding wheel matrix provided by the invention has the advantages of less connecting seam width and good integrity of the embedded lumps, reliable working properties, and safe structure suitable for the ultrahigh-speed grinding.

Description

technical field [0001] The invention relates to a combined brazing superhard abrasive grinding wheel substrate, in particular to a combined brazing superhard abrasive grinding wheel substrate suitable for ultra-high-speed grinding. Background technique [0002] The base body of the combined brazing superabrasive grinding wheel has an outer circular surface for brazing abrasive grains, and several connecting seams formed by interconnecting inserts are evenly distributed on the outer circular surface. The large width of the connecting seam causes the abrasive grains brazed on the outer circular surface to be unequally spaced, which leads to fluctuations in the grinding force of the combined brazed grinding wheel and affects the grinding quality. The effect on grinding quality is more obvious under ultra-high speed grinding conditions. At the same time, the traditional combined brazed grinding wheel structure cannot meet the design requirements of anti-deformation under the ac...

AI Technical Summary

Problems solved by technology

At the same time, the traditional combined brazed grinding wheel structure cannot meet the design requirements of anti-deformation under the action of ultra-high speed and large centrifugal force

Although the integral brazed superabrasive grinding wheel does not have the above-mentioned joints and the distance between the abrasive grains is uniform, its manufacturing size should not be large, so it is not suitable for ultra-high-speed grinding
