Abstract
The present disclosure relates to a floor grinding machine for grinding floor surfaces of stone or stone-like material. Such a machine comprises a machine frame, a grinding head 2, supported by and being rotatable relative to the machine frame, a grinding head hood 2, which defines a space in which the grinding head 1 is rotatable, a hollow and resilient member 4, arranged in the space, and a pressurized fluid source, operatively connected to the hollow member 4 to supply said pressurized fluid, whereby the hollow member 4 is resiliently expandable upon supply of said fluid.
Claims20
A floor grinding machine for grinding floor surfaces, the machine comprising:
- a machine frame,
- a grinding head, supported by and being rotatable relative to the machine frame,
- a grinding head hood, which defines a space in which the grinding head is rotatable,
- a resilient member arranged inside the space in which the grinding head is rotatable, and
- a pressurized fluid source, operatively connected to the resilient member to supply said pressurized fluid,
- whereby the resilient member, or a portion thereof, is resiliently expandable upon supply of said fluid and provides a dimensional change in at least one direction and exhibits a force sufficient to remove grinding residues accumulated on or proximate to the resilient member upon supply of the of the fluid.

- a grinding head hood, which defines a space in which the grinding head is rotatable,
- a resilient member arranged inside the space in which the grinding head is rotatable, and
- a pressurized fluid source, operatively connected to the resilient member to supply said pressurized fluid,
- whereby the resilient member, or a portion thereof, is resiliently expandable upon supply of said fluid, and wherein the resilient member comprises a closure which is biased towards a position where it closes an aperture, and wherein the resilient member is movable to allow fluid to flow through the aperture on supply of said pressurized fluid.
A method of operating a floor grinding machine for grinding floor surfaces, comprising:
- providing a resilient member on a grinding head of the floor grinding machine, and
- applying a pressurized fluid to the resilient member such that the resilient member expands upon supply of said pressurized fluid and provides a dimensional change in at least one direction and exhibits a force sufficient to remove grinding residues accumulated on or proximate to the resilient member,
- wherein the resilient member is arranged inside a space in which the grinding head is rotatable.
