EN 10083-1 46CrS2 Material Machining Technology
When machining EN 10083-1 46CrS2 steel it is necessary to use minimal pressure. Too much pressure can cause the steel to deform, resulting in an incorrect part. Additionally, it is important to ensure that the tool and workpiece are at the same temperature in order to prevent warping and thermal tension. If possible, set up the machine in a ventilated area to further promote cooling.
