Abstract
A two-side working machine, comprising an upper and a lower working disc which hold on, and are fixed to, an upper and a lower carrier disc, and which are disposed coaxially with each other and are adapted to be rotationally driven relative to each other by a working motor via a driving shaft, wherein the working discs have formed therebetween a working gap in which flat workpieces are processed on both sides, and a distance measuring device which measures the distance between working discs in at least two radially spaced points of the working gap, whereby the upper carrier disc is suspended on a supporting ring which is connected to the upper working shaft so as to be fixed for rotation, an annular portion of the carrier disc and means which are externally controllable by the supporting ring and via which a radial force is applied to the circumference of the carrier disc about the circumference of the supporting ring by means of a force generator, and control means are provided which adjust the force on the force generator in dependence on the distance values measured by the distance measuring device or the pressure values measured by a force sensing device, respectively.
