A grinding wheel (18) is selected in its composition for machining and the infeed of the grinding wheel (18) is set as a function of the geometry, the material and the desired surface finish of the camshaft (12) and the cams (30). sIn order to achieve a minimum grinding time while allowing for various restrictions due to the process, a maximum ...
The cam profile and the cam tappet interface are normally produced by grinding the surfaces. Typically, a simple grinding operation will produce the surface finish that is measured at 0.25 micron as a centre-line-average (CLA). This is the average height of the asperities on the surface. If the surface is first
The proposal is for a process and a machine for grinding concave-flank cams of a camshaft using a first and a second grinding wheel for pre and finish-grinding the cam, in which the pre-grinding process gives the cams a modified intermediate shape, and a third grinding wheel, the diameter of which corresponds to about double the radius of the concave flanks, whereby the concave flanks are pre ...
