A buffer brush (100) and a method of buffing, wherein the buffer brush (100) comprises endplates (102; 128) having a plurality of openings (104; 130) and between the endplates (102; 128) a plurality of brush segments (112; 132) comprising a brush segment core (116; 138) and brush bristles (114; 136) extending radially from the brush segment core (116; 138), The brush segment core (116; 138) has openings (118) configured for air flow laterally across the brush segments (112; 132) and vents (120; 122) configured for air flow radially from the vents (120; 122) through the brush bristles (114; 136) of each brush segment (112; 132) towards the ends of the brush bristles (114; 136). The buffer brush (100) is cooled by rotating the buffer brush (100) such that air flows laterally through the brush segment cores (116; 138) and radially through the vents (120; 122) and the brush bristles (136) of each brush segment (112; 132). |
