Problems solved by technology

These two methods of "occupancy" to manufacture porous grinding wheels will be limited by the upper limit of the amount of solids, resulting in a limitation of the upper limit of the porosity of the resin grinding wheel; at the same time, the viscosity of the resin liquid is high, which makes it difficult to mix the molding materials evenly. To a certain extent, the pores of the resin grinding wheel are distributed unevenly

Embodiment

[0014] A kind of preparation method of superhard resin grinding wheel of the present embodiment, comprises the following steps:

[0015] 1. After the hollow balls are baked in an oven at 90°C for 3 hours, they are evenly mixed with diamonds and passed through a 120-mesh screen;

[0016] 2. Stir and heat the epoxy resin solution in a water bath at 60°C for 3 minutes, add 40% of the total amount of diluent and coupling agent, continue stirring and heating for 6 minutes, then add the hollow spheres obtained in step 1 and Diamond mixture, continue stirring and heating for 10 minutes;

[0017] 3. Lower the temperature of the water bath in step 2 to 66°C, mix the remaining diluent and curing agent evenly, add it to the slurry obtained in step 2, stir it evenly, pour it into the mold, and harden at 70°C for 8 hours , and then solidified;

[0018] 4. Lower the solidified material in step 3 to room temperature for demoulding to obtain a grinding wheel ring;

[0019] 5. The superhard...

Abstract

The invention discloses a preparation method of a superhard resin grinding wheel, which comprises the following steps: ① After drying the hollow balls in an oven for a period of time, they are evenly mixed with diamonds and passed through a sieve; ② Stirring and heating the epoxy resin liquid in a water bath , add diluent and coupling agent, continue to stir and heat, add the mixture of hollow spheres and diamonds obtained in step ①, continue to stir and heat; ③ lower the temperature of the water bath in step ②, mix the diluent and curing agent evenly, and then add into the slurry obtained in step ②, stir evenly, pour it into the mold, and then solidify after hardening; ④ lower the solidified material in step ③ to room temperature and demould, and obtain a grinding wheel ring, which can be obtained after processing. Resin grinding wheel.

Description

technical field [0001] The invention belongs to the technical field of casting, and in particular relates to a preparation method of a superhard resin grinding wheel. Background technique [0002] In the past, porous resin grinding wheels mostly mixed water-soluble particles or hollow materials into the flowing slurry to form a "occupancy". [0003] In the case of "position", pores are generated. The water-soluble particle method is mainly to "occupy space" by adding water-soluble particles that can form pores into the abrasive layer. The hollow material method is to add a hollow spherical closed-cell material to the grinding wheel. Porous structure. These two methods of "occupancy" to manufacture porous grinding wheels will be limited by the upper limit of the amount of solids, resulting in a limitation of the upper limit of the porosity of the resin grinding wheel; at the same time, the viscosity of the resin liquid is high, which makes it difficult to mix the molding ma...
