Floor processing machine with tiltable finishing units

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...

AI Technical Summary

Benefits of technology

[0012]By the finishing units being tiltable relative to the frame, the finishing machine can be designed so that it can finish a wide trace and thus has great capacity while at the same time the machine can be made sufficiently narrow to be transported on a lorry or trailer, and to be able to pass through gates etc. to the area which is to be finished. Another advantage is that standard-type finishing units can be used, so that no specially made finishing units have to be provided, which contributes to reducing the cost of the finishing machine.

[0029]In one embodiment, the finishing machine comprises a driver's seat having an operator's seat and an actuator. Such a finishing machine is thus ridable, which reduces the physical efforts that are associated with finishing.

Problems solved by technology

A drawback of this type of finishing machine is that it has a low capacity, which is disadvantageous when grinding large surfaces.

However, also this grinding machine suffers from the drawback of low capacity.

Also this finishing unit suffers, however, from the drawback of low capacity.

A problem of this finishing unit is that the greater the capacity of the finishing unit, the more difficult the operating and transporting of the same.

Also this machine has a low capacity and requires the operator to walk behind the machine for steering the same.

Also this mobile grinding machine suffers from problems with regard to capacity.
