Example Embodiment
[0044] Example 1
[0045] A medical insulin needle grinding wheel, its raw material components and weight percentage content are: 2500 mesh silicon carbide 65%, 1200 mesh ceramic corundum 11%, modified resin 12%, glass beads 7%, cryolite powder 2%, oxidation Zinc 3%. The raw material components and weight percentages of the modified resin are 91% phenolic resin and 9% nitrile rubber. The particle size of cryolite powder is 280 mesh, and the diameter of glass beads is 0.5 mm.
[0046] The manufacturing process steps of this embodiment are as follows:
[0047] 1) Mixing: Pass the weighed ceramic corundum abrasives and silicon carbide abrasives through a 150# sieve, pour them into the mixing pot and mix for 10 minutes, add modified resin and mix for 30 minutes, add glass beads and other fillers and mix for 10 minutes , Pass 46# sieve;
[0048] 2) Turn on the preheating device of the molding equipment, set the pressure head temperature to 100~120℃, and set the turntable temperature to ...
