The invention provides a preparation method of
a diamond roller for efficiently trimming a CBN
grinding wheel. The preparation method comprises the following steps that S1,
diamond particles and
copper-iron
alloy powder are taken and put into a micro stirrer for being stirred to obtain mixed
powder, a
lubricant is added into a mixture, and continuing stirring is carried out to obtain a mixture; S2, the mixture is put into a
graphite mold, the mixture is pressed into a
metal sheet, put into a medium-frequency
sintering machine for
sintering, and is cooled to obtain
a diamond alloy sheet; S3, aroller base body is machined, the
diamond alloy sheet is put into a high-frequency heating
machine to be heated, the
diamond alloy sheet is taken out and rapidly sleeves the roller base body, and thediamond roller is obtained after cooling; and S4, the diamond roller obtained in the S3 is polished,
dynamic balance is carried out, cleaning and
drying are carried out, antirust oil is sprayed, packaging and storing are carried out. In conclusion, the preparation method of the diamond roller for efficiently trimming the CBN
grinding wheel has the advantages of novelty, convenience in operation, low cost, long product service life and the like.
