Abstract
The disclosure is directed to a device for the sharpening, grinding and polishing of dental, parodental or surgical instruments, comprising a grinding body (48) with a grinding surface, said grinding body (48) being carried by a support structure (36) consisting of arms forming a rectangle, with the support structure (36) being arranged for rotation and the instrument (12) to be ground being clamped in a clamping means (28). The rotatable support structure (38) is displaceable relative to the clamping means (28).
Claims23
A device for the sharpening, grinding and polishing of dental, parodental or surgical instruments, comprising
- clamping means (28) for clamping the instrument (12) to be ground,
- grinding body (48) provided with a grinding surface (68) and being rotatably supported on a bearing block (38), a base housing (14) having a rotatably supported support structure (36) projecting therefrom for holding said bearing block (38), said support structure (36) comprising at least two support arms (42) respectively articulated to the bearing clock (38), and at least one connecting member (54) additionally connecting said support arms (42),
- control member (74) having the support structure (36) abutting thereon and by which the support structure (36) and, through the support structure (36), the bearing block (38) holding the grinding body (48) is pivoted by pivot means (44, 52, 56) for changing the inclination of the grinding surface (68),
- said support structure (36) is rotatably arranged and the control member (74) is rigidly arranged on a common holding element (76) supported by the base housing (14) for longitudinal displacement along at least one axis extending perpendicularly to a rotational axis of the support structure (26), and
- fixing means (85) for fixing the holding element (76) and for releasing the fixed holding element (76).

- a clamping means (28) for clamping the instrument to be ground,
- a grinding body (48) provided with a grinding surface (68) and being rotatably supported on a bearing block (38), a base housing (14) having a rotatably supported support structure (36) projecting therefrom for holding said bearing block (38), said support structure (36) comprising at least two support arms (42) respectively articulated to the bearing block (38), at least one connecting member (54) additionally connecting said support arms (42), and
- a control member (74) having the support structure (36) abutting thereon and by which the support structure (36) and, through the support structure (36), the bearing block (38) holding the grinding body (48) is pivoted by pivot means (44, 52, 56) for changing the including of the grinding surface (68),
- said support structure (36) is rotatably arranged and the control member (74) is rigidly arranged on a common holding element (76) supported by the base housing (14) for longitudinal displacement along at least one axis extending perpendicularly to a rotational axis of the support structure (26),
- fixing means (85) for fixing the holding element (76) and for releasing the fixed holding element (76),
- an auxiliary adjusting means (138, 140;
- 168) for adjusting the instrument (12) prior to clamping by the clamping means (28) by clamping an end of the instrument (12) such that a facial surface of the instrument (12) extends perpendicular to a rotational axis of the support structure (36), and the clamping means (28) is movable along a plurality of axes so that the clamping means (28), while the instrument is held by the auxiliary adjusting means (138, 140;
- 146) is moved to the instrument in such a manner that the instrument (12), while maintaining its orientation determined by the fixing of the end to be treated, is clamped on its handle portion.
