Patent ID: 8162721

Claim:
A surface grinding machine for through-feed grinding workpieces by grinding stones rotating around the axes of spindles, said surface grinding machine comprising elastic holding means for holding the grinding stones tiltably around a tilt axis, wherein an entrance of said workpieces occurs to one side of said tilt axis and an exit of said workpieces occurs to another side of said tilt axis with respect to the grinding stones, said tilt axis being in such a position that when the grinding stones tilt against the force of the elastic holding means due to grinding loads generated on the entrance sides of the grinding stones that produce an axial displacement of the grinding stones tilt axis in an escape direction, a responsive entrance displacement and a responsive exit displacement occur in the grinding stones, respectively at entrance and exit of the workpieces, wherein during said axial displacement the axial displacement and exit displacement are of approximately a same magnitude and opposite direction.
