example 1
[0034] Step 1, the base cloth 2 is coated with a layer of double-sided adhesive and combined with the mesh cloth 4;
[0035] Step 2, the weighed single crystal diamond abrasive grains (170 / 200 mesh), resin binder, sodium chloride pore forming agent, copper powder resin reinforcing agent, alumina auxiliary abrasive grains are according to mass ratio 53:30: 1.5:0.6:3 for mixing, then pour into the prepared mold, completely cover the mold with base cloth 2 combined with mesh cloth 4 and flatten, add azobisisobutyronitrile accounting for 0.5% of the resin content and heat Curing agent is used to initiate curing, demoulding to obtain a protruding layer containing abrasive grains in the form of a cylinder, the protrusions are arranged as an oblique abrasive grain layer, and the height of the protrusions is 0.5 mm, and then post-cured;
[0036] Step 3: Connect the above-mentioned abrasive belts end to end, install them on the abrasive belt grinder, and grind the silicon carbide wafer...
