Method for de-burring or rounding edges of workpiece

摘要

The workpiece edges (12) are milled in a first processing step and then in a second step are rounded by spur brushing a surface (24) having the workpiece edges Where the workpiece is a vehicle tyre rim the edge is milled by a segment-like break (24) formed in an end wall (22) of the rim (14) which is turned about a corresponding angle for milling. A milling device can be set to a further break and the milled circulating edges of the breaks are rounded through spur brushing an internal surface of the end wall having the edges. The edges can be brushed by rotating the brush (54) and/or the rim.
