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.
