| An abrasive plate having an abrasive surface for performing abrading applications is provided. The plate includes a base member having a substantially smooth surface with a plurality of holes formed therethrough. A plurality of pairs of spaced apart slots radiate outwardly from each of the holes to define tab members. The tab members may be selectively raised or deformed to protrude from the smooth surface to collectively form an abrasive surface. The number of tabs raised may be selected to control the coarseness of the surface. | ||||||
| 108 | Implement for abrasion | US491966 | 1983-04-19 | US4571184A | 1986-02-18 | Svante R. Edwardson |
| A dental implement for abrasion, comprising a steel spatula coated on its opposite broad surfaces with an abrasive coating of tungsten applied to the steel surfaces with the aid of an electric arc. The implement is particularly useful for dentistry, because the tungsten has very little effect on the relatively hard tooth enamel but is quite abrasive on such dental materials as gold, amalgam, and dentine. Thus the implement is especially suited to smoothing tooth fillings of various types where the tooth enamel is to be left intact but the foreign material is to be evened out to make as smooth a transition as possible to the surrounding tooth enamel. | ||||||

| A grinding machine particularly for grinding the teeth on a carbide cutter. The machine includes a carriage swingably mounted on a frame for oscillation about a pivot axis. The carriage has a grinding wheel mounted thereon and rotatably driven by a motor which is also mounted on the carriage. The wheel is rotatable about an axis which is approximately parallel to but spaced from the pivot axis. A feeding mechanism projects outwardly from the front face of the grinding wheel at an angle of approximately 45.degree. relative to the rotational axis. The feeding mechanism releasably supports a carbide element. The feeding mechanism is linearly advanced toward the grinding wheel in an intermittent steplike movement which is synchronized with the oscillating movement of the carriage so that the grinding wheel cuts a groove across the carbide element during both the forward and return swings of the carriage. The grooves cut in the carbide element form cutting teeth therebetween, which teeth have a rounded convex configuration due to the engagement of the carbide element with the grinding wheel at a location between the pivot and rotational axes. | ||||||

| A file having a convex surface with a multiplicity of spaced depressions therein. At least some of the depressions are spaced from all the others and include an adjacent upset cutting lip. The surface of each of at least some of the depressions defines an arc in one plane; the arc being coextensive with the gullet of that depression; and the length of the chord from one end of the gullet to the other being greater than the width of the depression in an orthogonal plane.
