Embodiment 1
[0021] Refer to attached figure 1 :
[0022] Diamond thin film grinding method, comprises the following steps:
[0023] (1) Mix catalytic abrasive grains and cutting abrasive grains with binder respectively, the respective volume percentages are: abrasive grains 80% to 90%, binder 10% to 20%, stir evenly, of which catalytic abrasive grains account for the total The volume of abrasive grains is 60% to 80%, and cutting abrasive grains account for 40% to 20% of the total abrasive grain volume;
[0024] (2) Manufacture a concentric mold, pour the mixed abrasive grains in the way of catalytic abrasive grains and cutting abrasive grains, the catalytic abrasive grains are located in the outermost layer, and pour into molding;
[0025] (3) Put the grinding tool into the compressor to squeeze and solidify, and then the catalyst grinding wheel is obtained after demoulding.
[0026] (4) When the catalyst grinding wheel processes the workpiece, under the friction and catalysis of the c...
Embodiment 2
[0028] Refer to attached figure 1 :
[0029] This embodiment discloses a catalyst grinding wheel suitable for the diamond film grinding method, and the grinding wheel is composed of catalytic abrasive grains 1 and cutting abrasive grains 2 .
[0030] The catalytic abrasive grains 1 and cutting abrasive grains 2 are distributed in layers of concentric circles, and the catalytic abrasive grains 1 are located in the outermost layer.
[0031] In the grinding wheel, the catalytic abrasive grains 1 and the cutting abrasive grains 2 are bonded in a fixed manner, and the respective volume percentages are: 80% to 90% of the abrasive grains, 10% to 20% of the binder, and each part accounts for the abrasive grains The percentage of the total volume is: 60%-80% of catalytic abrasive grains and 40%-20% of cutting abrasive grains.
[0032] The catalytic abrasive grains 1 can be one of iron, manganese, titanium, aluminum or a mixture of more than one.
[0033] The diameter of the catalyti...
Embodiment 3
[0040] This embodiment proposes a specific formula for the catalytic grinding wheel. The catalytic abrasive grains of this embodiment are 1500# iron powder, the cutting abrasive grains are 1000# single crystal diamond powder, and the binder is 2400# iron powder. The volume percentage of each part is: the abrasive grains account for 80% of the total volume (the volume ratio of catalytic abrasive grains and cutting abrasive grains is 70%:30%), and the binder accounts for 20% of the total volume.
