摘要:
The invention relates to a machining device for machining a workpiece, wherein a rotatably mounted machining tool (2a) is held in a machining unit (2), and the axis of rotation (X) of the machining tool (2a) can be aligned with the workpiece surface to be machined, and therefore the axis of rotation (X) coincides with the geometric normal (N) in the machining point of the workpiece surface. The machining device comprises a pressure plate (6) mounted in a freely rotatable manner on the machining device via a bearing device (4), and a measuring device (8) for detecting a deviation in the position of the pressure plate (6). According to the invention, the bearing device (4) has a bearing body (40b) having at least one spherical surface region, and a bearing receptacle (40a) which surrounds the bearing body (40b) at the spherical surface regions in a form-fitting manner.

The invention relates to a machining device for machining a workpiece (W), wherein a rotatably mounted machining tool (2a) is held in a machining unit (2), and the machining unit (2) can be moved axially along the axis of rotation (X) of the machining tool (2a) by means of a feed device (10). The machining device comprises a pressure plate (6), mounted in a freely movable manner by means of a bearing device (4), and a measuring device (8) for position detection. According to the invention, the pressure plate (6) and the bearing device (4) constitute part of a pressure-exerting unit (12), and the pressure-exerting unit (12) can be moved axially with respect to the machining unit (2) in the direction of the axis of rotation (X) and independently of the machining unit (2) by means of a drive device (14) assigned to said pressure-exerting unit.
