Machine for vibratory grinding of workpieces

摘要

Method for vibratory grinding of workpieces by means of abrasive bodies or the like under the influence of accelerative forces, wherein a homogenous, substantially horizontal stream consisting of workpieces and abrasive bodies is circularly limited in its lateral expansion and is moved as a whole around a substantially horizontal axis. The machine for vibratory grinding of workpieces by means of abrasive bodies or the like, in which the aforementioned method is applied, has a substantially horizontally disposed drum receiving the stream of workpieces and abrasive bodies and being completely filled therewith, being substantially stable in space with respect to rotation and having a circular cross section; this drum is movable in a circular path or the like, wherein the angular velocity of the drum wall around the axis of the drum is substantially "zero"; the drum has an inlet orifice at its one end and at its other end an outlet orifice which is adjustable with respect to its cross-sectional area.
