Abstract

PROBLEM TO BE SOLVED: To provide a smaller, lighter weight and inexpensive apparatus while achieving an even grinding by rotating a spherical abrasive material to grind a bowling ball. SOLUTION: In an apparatus for grinding the surface of a bowling ball 4, grinding is performed by rotating a spherical abrasive material 9, not done by rotating the bowling ball 4 by a power in the past. At the same time, the ball 4 is placed on a freely rotatable frame 1 and is rotated by utilizing the rotation of the grinding material 9 thereby achieving even grinding as a whole.

2. Description of the Related Art A surface of a bowling ball is scratched every time a ball is thrown due to friction with a lane, and the trajectory of the ball after the ball is thrown may be disturbed by the scratch. Also, changing the coefficient of friction with the lane by changing the roughness of the ball surface,
The track may be tailored to the athlete's preference. Therefore, the surface of the ball is frequently polished. Conventionally, the ball is placed on a gantry that is rotated by a motor or the like, and sandpaper or the like is pressed against the ball.

The conventional gantry for rotating the ball itself has the weight of a bowling ball.
It required a powerful motor and large equipment. Further, since the spherical ball surface is polished with a flat sandpaper, it is difficult to uniformly polish the entire surface, and there is a disadvantage that the periphery of the finger hole and the hole for balance adjustment is excessively shaved.

According to the present invention, an abrasive having a concave spherical surface conforming to the diameter of a boring ball is rotated by a small motor, so that a small, lightweight and uniform polishing can be easily performed. is there. Further, the bowling ball is placed on a rotatable base to impart rotation to the ball, and as a result, the entire surface of the ball can be polished.

With the construction of the above means, the ball is placed on a rotatable base, and the rotating polishing part is pressed against the vertex of the ball (on the extension of the rotation axis of the base). Also start spinning. Since the bowling ball is heavy, once it starts to rotate, it does not stop easily due to inertia. If the polishing is performed while shifting the polishing portion in the lateral direction, the whole can be uniformly polished. At this time, the rotation of the ball can be continued by slightly inclining the grinding unit so that the rotation of the grinding unit matches the rotation direction of the ball and pressing the grinding unit against the ball. Next, when the ball is turned upside down and placed on a gantry, and polished in the same manner as described above, the entire ball can be polished uniformly.
