Embodiment Construction

[0041]FIG. 1 shows a riding finishing machine 1, which comprises a frame 14 (FIG. 2), on which a set of wheels 2a, 2b, 2c, 2d is arranged, so that the finishing machine can travel on a base 20 (FIG. 2).

[0042]The frame 14 of the finishing machine is arranged to support essentially all parts of the finishing machine. The frame can be a substantially rigid frame element or bottom plate, or be hinged, for the purpose of, for instance, facilitating manoeuvring.

[0043]The set of wheels 2a, 2b, 2c, 2d serves to provide a two-dimensional supporting surface for the finishing machine 1 on the base 20 and can be designed in various ways, depending on which driving properties are required for the machine.

[0044]The frame also supports an engine 6. The engine dimension and the choice of compulsion force / fuel are determined based on the capacity required by the finishing machine 1. In one embodiment of the finishing machine 1, the engine can be a gas-driven or diesel-driven internal combustion engi...

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).

Description

FIELD OF THE INVENTION[0001]The present invention relates to a processing or finishing machine for grinding, polishing and / or machining of hard floors, such as terrazzo, marble, stone, concrete floors and the like, according to the preamble to claim 1.BACKGROUND ART[0002]Machines for grinding hard floors, such as terrazzo, marble, stone, concrete floors and the like, are known and marketed by, inter alia, the applicant. Prior-art grinding machines for this purpose usually consist of a rotatably mounted solar disc which is driven by an electric motor and on which a plurality of, usually three to six, planetary disc are arranged. On each of the planetary discs there are arranged one or more holding plates, which each support one or more grinding elements, polishing elements and / or cutting tools. The grinding machine usually has a handle bar, adjacent to which actuating means are positioned; wheels, which constitute supports and facilitate the handling of the grinding machine, and opti...
