Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing an electrodeposited grindstone having a uniform abrasive grain distribution.

Conventionally, the manufacturing method for this type of electrodeposited grindstone was to use Ni
Alternatively, by mixing superabrasive grains such as diamond or CBN into a plating liquid such as Ni-Cr and electroplating the surface of the whetstone base metal with this plating liquid, the superabrasive grains are transferred to the whetstone base metal using the plating metal. A method of fixing it was used. However, with this method, the distribution of the superabrasive grains becomes uneven, so the grinding load on each abrasive grain on the resulting electrodeposited grinding wheel also becomes uneven, which has the disadvantage that the original characteristics of the superabrasive grains cannot be demonstrated. .

This invention was made with the aim of improving this drawback, and involves laying a non-conductive net on the surface of the grinding wheel base metal to which superabrasive grains are to be attached, and placing the superabrasive inside each square of the net. After storing the abrasive grains, temporary plating is performed to temporarily fix each superabrasive grain, and then the net-like body is removed and main plating is performed on top of it, so that the superabrasive grains are fixed to the whetstone base metal. The present invention provides a method for manufacturing an electrodeposited grindstone with a uniform abrasive grain distribution, thereby making it possible to easily obtain an electrodeposition grindstone having a uniform abrasive grain distribution.

An embodiment of the present invention will be described below with reference to the drawings. In the drawings, reference numeral 1 denotes a non-conductive net-like body made of plastic, fiber, etc., with rectangular square meshes each having a side of, for example, 0.2 mm or less. 1a. This net-like body 1 is laid on the surface of the grinding wheel base metal 2 on which the grinding surface is to be formed, and one superabrasive grain 3 made of diamond or CBN is arranged in each grid 1a as shown in FIG. . Note that the particle size of the superabrasive grains 3 used at this time is approximately 0.01 to 0.1 mm. Next, electroplating is performed on the mesh body 1 and superabrasive grains 3 using a plating liquid such as Ni or Ni-Cr, and each superabrasive grain 3 is temporarily fixed to the surface of the grinding wheel base metal 2 with a plating metal. do. The thickness of the plating layer at this time is about 0.02 mm. Once the superabrasive grains 3 have been temporarily fixed, when the net-like body 1 is removed from the surface of the grinding wheel base 2, each superabrasive grain 3 is temporarily fixed in a uniform distribution as shown in FIG. Become. In addition, FIG. 4 shows a temporarily fixed state viewed from the side. After the temporary fixing of each superabrasive grain 3 is completed, final plating is performed from above to fix each superabrasive grain 3 to the surface of the grinding wheel base metal 2, so that each superabrasive grain 3 becomes as shown in FIG. An electroplated grindstone can be obtained which has a grinding surface in which the superabrasive grains 3 are uniformly distributed and firmly fixed to the surface of the grindstone base metal 2 by the plated metal 4 as shown in FIG.

In the above embodiment, the mesh 1 has square meshes 1a.
Although we have explained the case where a bias mesh 1 is used as shown in FIG.
should be arranged evenly.

As described in detail above, in this invention, a net-like body is laid on the surface of a grinding wheel base metal on which a grinding surface is to be formed, one superabrasive grain is stored in each cell of this net-like body, and then temporary plating is carried out. The super abrasive grains were temporarily attached to the surface of the whetstone base metal, and then the mesh was peeled off and final plating was performed to fix each super abrasive grain to the surface of the whetstone base metal. An electrodeposited grinding wheel with a uniformly distributed grinding surface can be easily obtained, which not only stabilizes grinding performance but also reduces local drop-off of superabrasive grains, further improving service life. .
