のドレッシング方法を提供することにある。However, in the above-mentioned prior art, the cylindrical surface of the flat superabrasive grindstone is dressed on the plane of the end surface of the dressing tool.
Depending on the positions of the dressing tool and the superabrasive grindstone, the widthwise shape of the dressed grindstone surface was not always straightened. In other words, the widthwise shape of the grinding wheel surface varies in a complicated manner depending on the position of the edge width of the dressing tool where the rotation axis of the superabrasive grinding wheel is located. For example, in the case of FIG. In the case of FIG. 5B, it is dressed in a concave shape. The object of the present invention is to solve the above-described problems, and in a method of dressing by cutting a cup-shaped dressing tool in a direction substantially perpendicular to the grindstone surface of the flat grinding wheel, the central portion of the grindstone has a less uneven grinding surface. ,
It is an object of the present invention to provide a dressing method for a grinding wheel capable of finishing both ends into a curved surface convex outward .

すなわち１／２Ｗに配置されている。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a side view showing a configuration when the present invention is applied to a surface grinder. Reference numeral 1 denotes a spindle head of a surface grinder, which is slidably held in a column (not shown) in the vertical direction in the figure. Reference numeral 2 denotes a grindstone shaft, which is rotatably held by the spindle head 1 and rotated by a motor (not shown). Reference numeral 3 denotes a superabrasive grinding wheel, and a grinding wheel shaft 2
Attached to. A dresser body 4 is fixed to the spindle head 1. Reference numeral 5 denotes a dresser head, which is slidably held in the dresser body 4 in the up-down direction in FIG. A spindle 7 is rotatably held by the dresser head 5 and is rotated by a motor 8. Reference numeral 9 denotes a cup-shaped dressing tool, which is attached to the spindle 7. The dressing tool 9 is formed of a normal grindstone, and has an outer diameter r o and an inner diameter r i . Then, the positional relationship between the superabrasive grinding wheel 3 and the dressing tool 9 is, as shown in FIG. 2 which is an AA cross section in FIG. 1, the distance between the rotating shaft 10 of the superabrasive grinding wheel 3 and the inner diameter of the dressing tool 9. l is 0~ (r o -r i) / 2 and a position, Aru preferably arranged such that the position of the (r o -r i) / 4 . Also, the rotation center O of the dressing tool 9 is
When the width of the superabrasive grindstone 3 is W, it is arranged at substantially the center in the width direction, that is, 1 / 2W.
