  • a surface grinding machine of this type is for example from the Druchschrift WO-A1-01 / 32361 known.
  • the object of the invention is to avoid the aforementioned disadvantages and to provide a surface grinding machine, with the flat workpieces with superimposed radial active movement one or two sides can be ground plan or plane-parallel.
  • the surface grinding machine should be suitable in particular for one- or two-side surface grinding with radial workpiece oscillations as well as for one- or two-side surface grinding with cycloidal workpiece movement.
  • the surface grinding machine should preferably be realized within a very compact space and be flexible by a modular structure for different kinematic concepts.
  • This object is achieved in that the grinding spindle and the abutment are mounted with corresponding guides on two pillar areas, which are arranged one above the other and aligned with each other and as parts of a continuous column formed.
  • a particularly stable and technically rather complex design for the storage of grinding spindle and abutment is given, which allows both an axial and radial delivery of the grinding spindle and / or the abutment depending on the expression.
  • radial pivoting of the grinding spindle (s) an exchange of flat grinding wheels and / or a change in the kinematics can be easily done, since a simple handling and in particular a shift to a parking position without increased effort is possible.
  • the guides of the grinding spindle and the counter bearing are for a rotary, in particular wegoffe, delivery formed so that an axis of rotation is formed by the guides. With tied delivery, a high delivery accuracy is given.
  • the abutment may be formed as a flange without pivot bearing or as a trained without pivot bearing receptacle for a workpiece holder, so that a corresponding flange or a correspondingly adapted workpiece holder can be provided there.
  • the grinding spindle and the abutment designed as a further spindle or grinding spindle can have at least approximately parallel aligned axes of rotation, so that with a corresponding rotational movement of the two spindle plane-parallel surfaces of the workpieces to be machined can be achieved.

  • the guides of the grinding spindle and the thrust bearing for an axial, in particular wegdeme, longitudinal feed can be formed so that a linear axis is formed by the guides.
  • the guides of the grinding spindle and the anvil can each be designed as hydrostatic guides, so that both rotational axis and linear axis are formed by the guides, whereby a good damping capacity is combined with a high rigidity.
  • the guides of the spindles on the continuous column can be mounted overlapping one another, wherein in each case a guide of a spindle between the two guides of the other spindle is mounted on the column, so that by a greater guide length a particularly high rigidity given is.
  • surface grinding wheels can be provided on both spindles, which are arranged one above the other, so that a two-sided machining of the workpieces in a workpiece is possible.
  • At least one flat grinding wheel in particular the upper flat grinding wheel, can preferably be mounted floating by means of a variable rigidity intermediate element arranged between the torque-resistant grinding wheel flange and the flat grinding wheel, so that at the start of grinding existing different heights of the workpieces to be processed in a single work piece can be compensated.
  • a rigid mounting of at least one in particular of both flat grinding wheels may be possible.
  • At least one face grinding wheel in particular the upper face grinding disc, be mounted lockable against floating during storage, so that by an adjustable flexibility, the rigidity during the course of the grinding process is adjustable, so that the risk of self-building vibrations can be reduced and thus a high dimensional accuracy of the workpieces by a short before reaching the size of the work then parallel trained working gap can be realized.
  • This can be realized, for example, by a polymer layer, by springs with adjustable pretension or by cylinders, in particular hydraulic cylinders, with adjustable pressure.
