CBN electroplating process is a commonly used surface treatment method.It can improve the hardness and wear resistance of CBN grinding wheels.
To avoid the CBN peeling off of the CBN grinding wheel,We need to pay attention to the following process.
1.Prepartion
Before electroplating, some preparation work needs to be carried out. Firstly, it is necessary to ensure that the surface of the tool to be treated clean and free of oil or impurities.Secondly, it is necessary to choose appropriate CBN electroplating solution and equipment to ensure that they meet the process requirements.Finally, the thickness and electroplating time of the electroplating layer should be determined based on actual needs.
2.Surface treatment
Before CBN electroplating, it is necessary to perform surface treatment on the treated tool to improve the adhesion of the electroplating layer.The commonly used surface treatment methods include grinding the wheels acid washing, and sandblasting.The purpose of surface treatment is to remove surface oxide layers and impurities, making the surface of the grinding wheel cleaner.
3.Electroplating process
The first thing is putting the grinding wheels into a cleaning tank and using suitable cleaning agents to remove surface oil and impurities.The cleaning time and temperature should be controlled according to the specific situation, usually around 10-30 minutes.
Pre treatment: Place the cleaned grinding wheels into a pre treatment groove for pre treatment, with the aim of improving the roughness and adhesion of the body surface.Common methods include electrolytic polishing and chemical activation.The pre-treatment time and temperature should be controlled according to the specific situation, usually around 10-30 minutes.
Electroplating: putting the grinding wheels into an electroplating bath for electroplating.The electroplating tank contains CBN particles and metal ions, which are deposited on the surface of the substrate through electrolysis. The electroplating time and temperature should be controlled according to the specific situation, usually around 1-4 hours.
Clean: taking out the electroplated grinding wheels, clean them in the cleaning tank. The purpose of cleaning is to remove electroplating solution, residues, and impurities.The cleaning time and temperature should be controlled according to the specific situation, usually around 10-30 minutes.
Drying: Place the cleaned grinding wheels into a drying oven for drying.Remove surface moisture.The drying time and temperature should be controlled according to the specific situation, usually around 1-2 hours.
4.Post processing
After completing the CBN electroplating, some post-processing work is also required.Firstly, the electroplating layer needs to be inspected to see if its thickness and uniformity meet the requirements.Secondly, grinding and polishing are necessary to improve the smoothness and flatness of the electroplating layer.Finally, quality testing should be conducted to ensure that the quality and performance of the electroplating layer meet the requirements.

The implementation of CBN electroplating process requires strict control of process parameters for each step, such as temperature, time, and current density.At the same time, regular equipment maintenance and replacement of electroplating solution are also necessary to ensure the stability and consistency of electroplating results.

JINCHENG electroplated CBN grinding wheels always insisted on the above production process, so JINCHENG can make sure your quality stable and avoid the CBN grit peeling off from the steel substrate.
