METHODS OF FINISHING MACHINE PARTS USING ABRASIVE TOOLS (SELECTED PART)
Abstract
An experimental investigation of the process of band grinding produced the following conclusions: (1) the effectiveness of the process was affected most by unit pressure, width of band, velocity and cross feed of band, as well as the diameter of the surface to be worked; (2) with increasing band velocity up to 25 m/sec the unit removal of metal rises in a convex curve, further increase of velocity involves an appreciable drop of unit removal; (3) with increasing band velocity the rate of wear rises following a concave curve, while the height of the micro-roughness diminishes linearly; (4) with increasing unit pressure the removal of metal rises in a convex curve, while the rate of the band wear, the unit loss of abrasives, and the effective grinding power rise in a concave curve; (5) with increasing diameter of the surface to be ground the removal of metal, rate of band wear, the unit loss in abrasives, and the magnitude of the micro-roughness follow the pattern of a declining hyperbolic curve; (6) the rate of metal removal decreases with increasing hardness and plasticity of the metal to be machined; and (7) the finish of the ground surface improves as the hardness of the metal being machined increases.
