Sphere grinding apparatus |
摘要 |
A sphere grinding apparatus (1) for grinding spheres by two discs consisting of a rotational disc (5) and a stationary disc (6), the sphere grinding apparatus (1) incorporating: a central shaft (3) slidable in an axial direction; and a housing (4) for rotatively supporting the central shaft (3), wherein the rotational disc (5) is joined to the central shaft (3) and the stationary disc (6) is joined to the housing (4). Accordingly, it is possible to provide a sphere grinding apparatus which is capable of improving a machining accuracy and which has a simple structure and the cost of which can be reduced.
