摘要： An iron-base article such as a camshaft has a remelted layer of high wear resistance on a cam surface, for example. To make such an iron-base article, molten metal is poured into a mold with a chill set therein to cast an iron-base article having a chilled region formed in contact with said chill. Then, metal powder which provides wear resistance upon being mixed is added to at least a portion of said chilled region. A high level of energy is applied to the portion of the chilled region to heat and remelt the same, and the remelted portion is thereafter cooled to form a remelted layer therein.

摘要： A cam grinding machine which includes a machine frame, a turning grinding wheel adjacent the frame, a swingable table positioned opposite to the frame, and a turnable work shaft for holding a workpiece mounted on the table. The table is controlled in the swing movement by a touch roller device mounted on the table and a master cam device mounted on the frame. The touch roller device is disposed to face and contact the master cam device so that the workpiece may be ground in correspondence to the master cam device by the grinding wheel provided on the forward side of forward and rearward swing direction of the table. The master cam device includes a driving shaft which is turned synchronously with the turning of the work shaft and is adjustable in its turning phase in relation to the work shaft.
