Electrochemical bond

Electrochemical bond means special procedure of deposit abrasive grains in a thin layer to the working surface of abrasive tool. Metal cations flow through a suitable solution with the aid of the electric current and are discharged in a thin layer onto the cathode (abrasive tool). The thickness of the coating depends on the size of the abrasive grains.

  • Resistant to deformation

  • High degree of cutting

  • High dimensional accuracy

Deformation resistance

The electrochemical bond is characterized by a ductile nickel coating, which means that it carry over plastic deformation without breaking the coating.

High degree of cutting

The grinding tools in the electrochemical bond are distinguished by a high degree of cutting and an open structure, which makes it possible to treat materials which cannot be treated with the resin and metal bond. The tools can be ground dry or wet. They can be used wherever high dimensional accuracy is required and for non-standard shape of grinding wheels.

Dimensional accuracy

The high concentration of grains in the coating enables the grinding tools to maintain their original shape and dimensions throughout their lifetime. In contrast to metal and resin bonds which have a closed structure, the structure and shape of the grain ensure faster material removal with minimal heat generation. In addition, by selecting the geometry of the blanks, they enable a targeted and very efficient adaptation to the required machining processes.

Diamond and CBN electroplated grinding and cutting tools can be successfully used for the treatment of following materials (table):
