Claims20
A coupling mechanism for an abrasive roll assembly comprising:
- a locking disk in association with an axial center of an abrasive roll assembly;
- a shaft fixed along the axial center of the locking disk such that the shaft and the locking disk have a common center of axis;
- a rotating means, an outer surface of which is fixed to the body of the apparatus to form the stationary end and an inner surface of which is fixed to an outer surface of a hollow guide and lock means to form a rotatable end such that the hollow guide and lock means is capable of being rotated with respect to the rotating means;
- and in an inner side of the hollow guide and lock means the shaft can be slide as desired to place the shaft in a desired position inside the hollow guide and lock means and to hold it rigid in the desired position inside the hollow guide and lock means wherein the locking disk can be moved as desired in accordance with the shaft movement such that the locking disk mates the abrasive roll assembly and holds the abrasive roll assembly intact with respect to the apparatus and that the shaft along with the locking disk can be rotated with respect to the rotating means and that the axis of rotation is along the axial center of the apparatus.

A rotating mechanism for an apparatus to hold and to rotate a shaft the rotating mechanism comprising:
- a hollow sleeve which has threading in its internal surface such that a shaft which has a mating thread on its external surface can be threaded along the axis of the sleeve;
- a bearing whose inner surface of is fixed to the outer surface the sleeve and the outer surface of the bearing is fixed to the apparatus;
- a retainer ring is fixed on to the bearing and the sleeve such that the shaft can pass though it and the bearing is intact with the sleeve and the apparatus;
- and
- a lock nut which can be threaded on to the shaft from the bottom of the sleeve such that the shaft can be locked at desired position in the sleeve wherein shaft can be rotated with respect to the bearing precisely in its center of axis and the axis of rotation is the axial center of the apparatus.
2 more elements
A milling apparatus comprising:
- a locking disk placed along an abrasive roll assembly which is in association with the axial center of the abrasive roll assembly;
- a shaft fixed along the axial center of the locking disk such that the shaft and the locking disk have common center of axis;
- a rotating means, the outer surface of which is fixed to the body of the milling apparatus to form the stationary end and the inner surface of which is fixed to the outer surface of a hollow guide and lock means to form the rotatable end such that the hollow guide and lock means is capable of being rotated with respect to the rotating means, and in the inner side of the hollow guide and lock the shaft can be slide as desired to place the shaft in desired position inside the hollow guide and lock means and to hold it rigid in desired position inside the hollow guide and lock means wherein the locking disk can be moved as desired in accordance with the shaft movement such that the locking disk mates the abrasive roll assembly and holds the abrasive roll assembly intact with respect to the apparatus and that the shaft along with said locking disk can be rotated with respect to the rotating means and that the axis of rotation is along the axial center of the milling apparatus.
