OD And ID Grinding Machines
OD And ID Grinding Machines
Erwin Junker Maschinenfabrik GmbH offers OD And ID Grinding. Grinding machines for grinding camshafts, cam pieces and individual cams combine non-cylindrical grinding for the cams and cylindrical grinding for the bearings. With non-cylindrical OD/ID grinding, the grinding wheel follows the cam contour through interpolation of the workpiece spindle (C-axis) with the grinding spindle (X-axis). CBN or diamond are used as an abrasive – for high cutting performance with a constant level of quality and a long tool life. The cam geometry is specified in a lift table. In the process, each angle is assigned a lift value to define the cam contour and import it to the program. The software then interpolates the values automatically. The cam contour is frequently concave in the infeed and discharge area. Here the concave radius determines the maximum grinding wheel diameter that can be used.
