Description
- The present invention concerns a grinding head adapted to rotate about a central axis, having a surface which is provided with grooves for reception of a number of abrasive elements, wherein edge profile parts are provided for reception in the grooves and wherein support brushes are associated with the edge profile parts.
-
EP 1633530 B1 describes a grinding head or an abrading disc of the kind indicated in the preamble of claim 1, intended for being rotated about a central axis. The abrading disc has a surface with radial retainer grooves for end parts of abrasive paper members with associated support brushes with a radial extension over the greater part of radius of the surface which has increasing height inwardly from the periphery. - The abrading disc is designed such that the surface has increasing height inwardly from a periphery of the surface, and so that the abrasive paper members have approximately radial extension across the greater part of radius of the surface. Hereby is ensured a stable and uniform grinding which is suited for grinding concave, convex and plane surfaces and recesses/countersinks.
- In order to achieve a more stable and good grinding of a surface, the abrasive paper members are distributed diametrically and evenly on the surface of the grinding disc such that the abrasive paper members here cover the greater part of the radius of the surface, entailing that the greater part of the grinding disc surface can be used for counter grinding.
- That the surface has increasing height inwards from the periphery of the surface causes the grinding wheel to be felt very stable as it is the centre part of the grinding disc which strikes the surface to be ground first. Around the centre part of the grinding wheel there will be no large lateral forces pulling the grinding disc across the surface, and therefore it will be easy to hold the grinding disc against the surface.

This publication describes different embodiment for a grinding head having abrasive elements extending in radial direction. The abrasive elements are received in the retainer grooves and are fastened therein by means of interleaves acting on a central part thereby providing two free ends of an abrasive element which is provided in the form of strip-shaped abrasive material.

DE 20 2004 002905 U1 describes a grinding head comprising a base plate having rod shaped abrasive elements fastened thereto. The rod shaped abrasive elements are arranged under their longitudinal axis in angle between +60° and -60°compared to an imaginary axis at right angle to the front surface of the base plate and measured in direction of rotation as a negative or positive working angle. With this grinding head it is not possible to use a number of successive abrasive paper members with associated support brushes. - On this background, the purpose of the invention is to indicate a further improved grinding head which makes it easier to achieve a more optimal grinding particularly of side edges and edge areas of plate-shaped items, e.g. blockboard and furniture doors, or corresponding plate-shaped items.
- The grinding head according to the invention is peculiar in that the surface is selected between a plane surface and a cylindrical surface, that each of the abrasive elements comprises the edge profile part for reception in the grooves being provided as retainer grooves and a number of abrasive paper members behind each of which abrasive paper members a row of support brushes is provided, that the edge profile part, that the abrasive paper members are mounted at an angle of 20-40°, preferably about 30°, directed obliquely forward in the direction of rotation of the plane surface and the tangential plane of the cylindrical surface, respectively. In a simple way is hereby readily achieved a more optimal abrading of particularly side edges and edge areas of plate-shaped items.
- For example, it is to be emphasised that grinding of outer edges of laser-cut items of metal sheeting can be optimised by the oblique angle directed forward in the direction of rotation, further facilitating the making of a slight chamfer or rounding of outer top side edges of laser-cut items of metal sheeting.
- The grinding head according to the invention is designed such that the retainer grooves for the edge profile parts of the abrasive paper members extend obliquely rearwards in the direction of rotation of the plane surface at an angle of 3-10° relative to a radial extension.
- Alternatively, the grinding head according to the invention is designed such that the retainer grooves for the edge profile parts of the abrasive paper members extend obliquely rearwards in direction of rotation of the cylindrical surface at an angle of 3-10° relative to an axially parallel generatrix of the cylindrical surface.
- The grinding head according to the invention may advantageously be designed such that the plane surface between the retainer grooves for the edge profile parts of the abrasive paper members is designed with radial suction apertures, and that the grinding head includes an enclosing housing which is provided along its periphery with an annular lip seal.
- The grinding head according to the invention may further suitably be designed such that the lip seal is constituted by brushes made of an electrically conducting material, e.g. carbon fibre brushes.
- With the object of further optimising the grinding head according to the invention, it can be designed such that side edges of the radial suction apertures have an inclined course downwards in the direction of rotation such that rotation of the plane surface can cause a sucking effect by itself.
- Suitably, the grinding head according to the invention is designed so that the support brushes consist of relatively soft brushes of pig's bristles.
