Then, the main plating layer 4 is electroplated to a thickness that fills the height of the ultra-hard abrasive grains by about half (see FIG. 2a), and the ultra-hard abrasive grains are applied to the main-plating layer 4 with a grindstone. It is retained on the surface of the core (see Figure 2b).

Then, the surface of the abrasive grains and the temporary plating layer temporarily attached to the grindstone core to accelerate the electroless plating is activated by activating a catalyst on the entire surface, and then the abrasive grains are temporarily attached. The thus-prepared whetstone core is subjected to main plating by electroless plating to hold the abrasive grains on the surface of the whetstone core.

It will not be overlapped with the surface of the and will be temporarily attached as a single layer. next,
The surface of the temporarily attached abrasive grains and the temporarily applied plating layer is preliminarily activated by applying a catalyst, so that the subsequent electroless plating of the main plating layer is the temporarily applied plating layer and the abrasive grains of the grindstone core.

る。EFFECTS OF THE INVENTION According to the method for producing an electrodeposition grindstone of the present invention, since super-hard abrasive grains are not plated during temporary attachment,
The ultra-hard abrasive grains are temporarily attached in a single layer without overlapping so that the abrasive grain distribution becomes uniform. Then, the main plating layer holding the ultra-hard abrasive grains reaches the surface of the ultra-hard abrasive grains and the holding power is improved, and the thickness of the main plating layer can be reduced. That is, it is possible to reduce the buried amount of the ultra-hard abrasive grains and increase the usable portion. Therefore, the life of the electrodeposition grindstone is extended, which is economical.
