Abstract
A finishing machine (1) for finishing a work surface (20) which consists of a floor of terrazzo, marble, stone, concrete or the like, comprises at least two finishing units (3a, 4a; 3b, 4b; 3c, 4c, 300) which are supported by the frame (14, 100) of the finishing machine and which are arranged for grinding, polishing and/or machining of the work surface (20), and each machining unit comprises a motor (4a, 4b, 4c, 200) and a rotatably mounted working disc (41) driven by the motor. The finishing units (3a, 4a; 3b, 4b; 3c, 4c, 300) are individually tiltable relative to the frame (14, 100) about respective axes that are substantially parallel to the work surface (20).

A finishing machine for finishing a work surface, comprising:
- a frame;
- and
- a plurality of finishing units supported by the frame, each of the finishing units configured to be tilted relative to the frame,
- the finishing units including at least a first finishing unit tiltable about an axis that is substantially perpendicular to a central axis of the finishing machine, and a second finishing unit tiltable about an axis that is substantially parallel to the central axis of the finishing machine.
A finishing machine for finishing a work surface, comprising:
- a frame;
- and
- a plurality of finishing units supported by the frame, each of the finishing units configured to be tilted relative to the frame, the finishing units including at least a first finishing unit tiltable about an axis that is substantially perpendicular to a central axis of the finishing machine, a second finishing unit tiltable about second axis that is substantially parallel to the central axis of the finishing machine, and a third finishing unit tiltable about a third axis, wherein the second axis and the third axis are configured to form an acute angle.
A method for finishing a work surface, comprising the steps of:
- providing a frame with at least two finishing units, the finishing units configured to be tilted relative to the frame, the finishing units including at least a first finishing unit tiltable about an axis that is substantially perpendicular to a central axis of the finishing machine, and a second finishing unit tiltable about an axis that is substantially parallel to the central axis of the finishing machine;
- providing a plurality of working discs rotatably mounted on each of the finishing units;
- and
- positioning the finishing units such that the working discs substantially engage the work surface.
