Abrasive support for hand grinders using corundum etc. coated surface

摘要

The abrasive support (2) consists of one or more combined flexible materials with curved or profiled working surface for machine-grinding three-dimensional surfaces with or without dust-exhauster and the support fixer can consist of a burr mechanism on the machine base or again a clamp (5) to hold the emery paper etc. as for swing-grinders. The support surface (3) can be coated in abrasive and in convex or concave form and is fitted out with channels (8) connected at one end to the suction opening on the support underside and otherwise to the support surface to draw off dust during operations. The surface can also be grooved out for more extensive dust removal.
