Abstract
In a grinding machine comprising a stationary wall part and a plate part which rotates about an axis of rotation, between which a gap is formed, the gap is limited from above by a ceramic part and from below by an elastic part.
Claims7
A grinding machine comprising:
- a stationary wall member;
- a plate member disposed for rotation about an axis;
- a ceramic part integral with one of said wall member and said plate member;
- and
- an elastic part integral with an other of said wall member and said plate member, wherein said ceramic part is disposed vertically above said elastic part, wherein said elastic part has a flat surface and wherein said ceramic part has a downwardly directed nose-like projection, the flat surface of the elastic part and the nose-like projection of the ceramic part facing each other and the upper surface of the elastic part extending parallel to the lower side of the nose-like projection.
