Mechanical deburring process where a file is used to process the workpiece surface so that its surface roughness is improved. Beskrivning The process The tool is usually made of hard metal and is knurled such that more subsequent cuts are created. The cutting inserts are angled so that cutting occurs when the file is pressed against the workpiece and moved forward. The files are available in many versions and diameters to suit different jobs. A common file is one that is flat on one side and rounded on the others to be able to process both round holes as in this case, and straight edges. File Deburring Process photos Process films
