Abstract (en)
[origin: WO2010051964A1] The invention relates to a ceiling grinder (1) comprising a drive unit (8, 9, 10), a grinding wheel (12), which can be set in rotation by means of the drive unit (8, 9, 10), a grinding head housing (6), which receives the grinding wheel (12) and has an opening (13) allowing the grinding wheel (12) access to the surface to be ground (14), and a holding element for holding the grinder (1). The ceiling grinder (1) also has means for producing a negative pressure within the grinding head housing (6), by which the ceiling grinder (1) is held on the surface to be ground (14), wherein the means for producing the negative pressure comprise lamellar elements, which rotate about the axis of the grinding wheel (12) during the grinding operation of the ceiling grinder (1) and thereby cause within the grinding head housing (6) an air flow that induces a static negative pressure.
