Abstract
A diamond wire cutting machine includes a spool on which a diamond wire is wound. The spool includes two end flanges having respective frustoconical faces adapted, by cooperation of shape with frustoconical faces of two adapters, to center the spool on an axis of revolution. A drum extends from one of the end flanges to another of the end flanges. The drum includes a cylindrical outer face of circular cross-section on which the diamond wire is wound. The drum defines a central hole through which a drive shaft passes. The drum and the end flanges form a single plastic block.
Claims10
A diamond wire cutting machine, comprising:
- a drive shaft extending along an axis of revolution;
- a motor capable of driving the drive shaft in rotation, about its axis of revolution, sometimes in one direction and sometimes in an opposite direction;
- two adapters each fixed to the drive shaft, each of the adapters comprising a frustoconical face centered on the axis of revolution, the frustoconical faces facing one another;
- a spool on which a diamond wire can be wound when a workpiece is cut by the cutting machine, the spool being immobilized in rotation and translation on the drive shaft by the two adapters, the spool comprising:
- two end flanges having respective frustoconical faces capable, by form-fitting cooperation with the frustoconical faces of the adapters, of centering the spool on the axis of revolution;
- and
- a drum extending from one of the end flanges an other of the end flanges, the drum:
- comprising a cylindrical outer face of circular cross-section on which the diamond wire is wound;
- and
- defining a central hole through which the drive shaft passes,
- wherein the drum and the end flanges form a single plastic block.
A spool, suitable for use in a cutting machine, for winding thereon a diamond wire during cutting of a workpiece by the cutting machine, the spool being adapted to be immobilized, in rotation and translation, on a drive shaft of the cutting machine by two adapters of the cutting machine, the spool comprising:
- two end flanges with respective frustoconical faces capable, by form-fitting cooperation with frustoconical faces of the adapters, of centering the spool on an axis of revolution;
- and
- a drum extending from one of the end flanges an other of the end flanges, the drum:
- comprising a cylindrical outer face of circular cross-section on which the diamond wire is wound;
- and
- defining a central hole through which the drive shaft passes,
- wherein the drum and the end flanges form a single plastic block.
