EN 10083-3 1.5530 Material Machining Technology
Cutting speed and feed rate are two of the most important machining parameters for EN 10083-3 1.5530 steel. The cutting speed should be selected in relation to the cutting tool's hardness and type, the feed rate should be matched to the cutting speed. The optimum cutting parameters will vary depending on the cutting tool selected and the part geometry. Generally, higher cutting speeds are associated with reduced surface finish, so care should be taken to ensure that the surfaces produced meet specifications.
