    • The present invention relates to a method and an arrangement for grinding spherical products (12), such as e.g. bowling balls, in particular. Such an arrangement comprises at least one grinding machine (1) having a spherically oscillating grinding movement. A fastening plate (6) fitted on the grinding machine has a spherically shaped bearing surface (7) and a grinding product (9) fitted on this, which through its slits (13) adopts a position with accuracy of shape on the spherically shaped surface. The grinding product (9) will form a contact surface (17) in the interface, in which the grinding product cooperates with the spherical product. This contact surface then adopts a radius of curvature arranged to substantially correspond to the radius (r) of the spherical product (12). The grinding is performed with a spherically oscillating grinding movement, which is adapted to the radius of the spherical product and simultaneously coincides with the radius of curvature of the contact surface.
    • 本发明涉及一种研磨球形产品(12)的方法和装置,例如, 保龄球,尤其是保龄球。 这种布置包括至少一个具有球形摆动磨削运动的研磨机(1)。 安装在研磨机上的紧固板(6)具有球形支承表面(7)和安装在其上的研磨产品(9),其通过其狭缝(13)在球形表面上采用形状精确的位置 。 研磨产品(9)将在界面中形成接触表面(17),其中研磨产品与球形产品配合。 该接触表面然后采用布置成基本对应于球形产品(12)的半径(r)的曲率半径。 磨削是通过球形摆动磨削运动进行的,其适用于球形产品的半径并且同时与接触表面的曲率半径重合。
