Abstract
The invention provides a measuring machine which includes a stationary measuring contact point and a movable measuring contact point, each of which is positioned so as to oppose each other. Measuring of an object is carried out by putting the object between the stationary measuring contact point and the movable measuring contact point. A spindle carrying the movable measuring contact point is supported by a linear bearing of the crossed roller type. The linear bearing supports the spindle in plural directions. Thus, the sliding motion of the spindle can be carried out smoothly to obtain the precise measuring value.
