Is the taper surface 107 of the flange portion 107 of the workpiece 106.
While being in contact with a, the grindstone 105 is moved in the axial direction of the rotary shaft 108 to grind the taper surface 107a (traverse grinding). In this case, in order to prevent interference between the grindstone 105 and the tailstock 103, it is necessary to let the right end portion of the grindstone 105 escape upward by H 1 from the left end portion, but since the surface to be ground is the tapered surface 107a, It is possible to let the right end part escape upward. However, unless the distance H 1 is made sufficiently large, the grindstone 105 may interfere with the tailstock 103.

ス研削する。FIG. 10 is an explanatory view when a tapered surface is traverse ground by a conventional angular grindstone. The reference numerals are different from those in the above publication. In the work 106, the protrusion width W 1 of the flange portion 107 is made larger than the width W 2 of the grinding surface 110a of the angular grindstone 110. The grinding surface 110a of the angular grindstone 110 is attached to the flange portion 107.
Contacting the taper surface 107a of No. 1 and moving the angular grindstone 110 in the Z-axis direction and the work 106 in the X-axis direction, the angular grindstone 110 is relatively moved in the direction of arrow A with respect to the work 106. To traverse.

Therefore, the distance H 1 shown in FIG. 9 can be set sufficiently large, and thus it is possible to prevent interference between the grindstone 110 and the tailstock.

Since 10 is relatively moved in the direction of the arrow A along the tapered surface 107a, movement control in the biaxial directions of the X-axis direction and the Z-axis direction is required, which makes it difficult to control the movement of the angular grindstone 110. .

Further, since the rotary grindstone can be moved along the first axis parallel to the surface to be ground of the work to grind the ground surface, the grinding surface of the rotary grindstone can be controlled by the movement control in one axis direction. It can move along the surface to be ground.

ことができる。The second aspect of the present invention is characterized in that the grinding surface width of the frusto-conical rotary grindstone is substantially the same as the width of the surface to be ground. Butt grinding (plunge grinding) becomes possible by making the grinding surface width of the rotary grindstone substantially the same as the grinding surface width. Therefore, it is not necessary to traverse the rotary grindstone along the surface to be ground of the work, so that the grinding time can be shortened.

The ground surface 11 of 0 has an inclination of α ° with respect to the rotating shaft 12, and the taper surface of the flange portion of the work has an inclination of β °.

0 is moved in the direction of the arrow along the second axis A 2 to bring the grinding surface 11 of the rotary grindstone 10 into contact with the tapered surface 7a of the flange portion 7. As a result, the tapered surface 7a of the flange portion 7 is plunge-ground with the grinding surface 11. After the grinding is completed, the rotary grindstone 10 is moved in the direction of the arrow along the second axis A 2 to separate the grinding surface 11 of the rotary grindstone 10 from the taper surface of the flange portion. Next, the rotary grindstone 10 is moved in the direction of the arrow along the first axis A 1 . Since the CBN grindstone is used for the rotary grindstone 10, high speed grinding is possible. Further, by plunge grinding the grinding surface 11 with a CBN grindstone, the grinding surface 1
A compressive stress is generated in 1 and the abrasion resistance of the ground surface 11 can be improved.

Traverse grinding is also possible. That is, FIG.
In, the grinding surface 11 of the rotary grindstone 10 is brought into contact with the taper surface 7a of the flange portion 7 to perform rough cutting by plunge grinding,
Next, the rotary grindstone 10 is moved in the direction of the arrow along the first axis A 1 so that the grinding surface 11 forms the taper surface 7a of the flange portion 7a.
Traverse grinding is performed.

Since the angle formed with the axis A 2 , that is, the inclination angle of the rotary shaft of the rotary grindstone) is set to a large value of 60 °, the contact area between the grinding surface of the angular grindstone and the taper surface of the workpiece increases,
Grinding burn may occur. However, since the angle of the rotary shaft corresponding to the angular angle of the rotary grindstone 10 according to the present invention is set to be smaller than (θ + α) ° and 60 ° as shown in FIG. 2, the contact area between the ground surface and the tapered surface is small. Can be reduced, and the occurrence of grinding burn can be prevented.

動させるトラバース研削を容易に行うことができる。The present invention has the following effects due to the above configuration. According to the first aspect of the present invention, the rotary grindstone is formed in a frustoconical shape in a divergent state, and the rotary grindstone is configured to be movable parallel to the first axis parallel to the surface to be ground. Therefore, when the rotary grindstone is brought into contact with the tapered surface to be ground, the inclination angle of the rotary grindstone increases, so that the interference between the rotary grindstone and the workpiece gripping member can be prevented. Further, since the rotary grindstone can be moved along the first axis parallel to the surface to be ground of the work to grind the ground surface, the grinding surface of the rotary grindstone can be controlled by the movement control in one axis direction. It can move along the surface to be ground. Therefore, it is possible to easily perform traverse grinding in which the rotary grindstone is moved along the surface to be ground of the work.

ことができる。According to a second aspect of the present invention, plunge grinding is possible by making the grinding surface width of the rotary grindstone substantially the same as the grinding surface width. Therefore, it is not necessary to traverse the rotary grindstone along the surface to be ground of the work, so that the grinding time can be shortened.
