Abstract: An abrasive, sanding and/or surface finishing apparatus designed to extend the useful life of abrasive material which employs a dual-platen arrangement having a particulate removal system designed to effectively remove particulate from the working area of the machine. Specifically, the particulate removal system is designed to remove particles from the surface of the work in the area of the gap created between the twin platens, with a secondary particulate removal system designed to remove material from the work following treatment by abrasive from both platens. The inlet port of the particulate removal system interposed between the platens is designed to occupy a substantial portion of the area within the gap zone between the platens. In addition to increasing the useful life of the abrasive, the particulate removal system reduces the release or discharge of dust into the ambient.

Abstract: An outer surface of a cam on a camshaft extending along a camshaft axis is honed by continuously rotating the camshaft about its axis, holding a grinding stone adjacent the cam with a surface of the stone directed radially inward at the cam surface, urging the grinding stone radially of the axis against the stone and thereby pressing the cam surface radially inward against the cam surface for contact of the stone surface along a line with the cam surface, and continuously displacing the stone surface in a direction generally tangential of the camshaft axis and thereby continuously moving the contact line between the cam and stone surfaces. Thus the contact line between the stone and the cam will move continuously, so that wear will not be concentrated in one location and the stone will not wear to fit in surface contact on the cam. The cam surface includes a part-cylindrical base region coaxial with the camshaft and a lobe region projecting radially outward from and joined to the base region.
