Electroplated diamond wheels
Common electroplated diamond grinding wheels can be used for sharpening band saw blades, Tormek grinders, brake pads.
It have high hardness and wear resistance, and the diamonds are evenly distributed.
Through the method of metal electrodeposition, the diamond is firmly wrapped on the matrix by the matrix metal. It is widely used in mechanical electronics, glass, building materials, oil drilling and other industries.
Electroplated diamond tools have strict requirements on the bonding force between the plated metal and the steel substrate. In some special industries, such as powerful grinding in the magnetic material industry and the ceramic industry, the feed rate is controlled at about 0.3mm or even more strictly.
However, due to the grinding force, temperature rise, impact of the workpiece, etc., the metal coating containing diamond will be separated from the steel substrate, resulting in the coating falling off.
In the production process of electroplated diamond tools, most manufacturers easily ignore the problem of the bonding force between the coating metal and the substrate. It is very common to cause the coating to fall off during use.
There are mainly the following three situations for the coating to fall off:
In the process of use, the peeling off of the coating is generally partial, and it is rare that the coating is completely peeled off at one time.
(1) The coating falls off to the surface of the substrate: that is, the diamond-containing metal coating and the diamond-free metal bottom coating are separated from the steel substrate at the same time.
(2) The layer falls off to the metal bottom coating: that is, the metal bottom coating without diamond is not separated from the steel substrate, but the diamond-containing metal coating is peeled off from the metal bottom coating.
(3) Lamellar separation of the coating metal in the diamond-containing metal coating: During use, the diamond-containing metal coating abnormally falls off in flakes or powder, and the diamonds do not fall off completely, but partially fall off in granular form. The shedding of diamond particles is visually manifested as continuous large holes on the surface of the tool, which should be the shedding of this type of coating.
During the use of electroplated diamond tools, if one of the above conditions is found, stop using the electroplated diamond tools for repair and inspection, so as not to cause greater damage to the machine.
