Machine for machining a volume, in particular an inlay, by automatic duplicating

A machine for machining at least one volume of work piece automatically by copying, comprising:

• a machining tool with an axis of symmetry and having at least one degree of freedom in rotation about the axis of symmetry, means for driving the rotation of said machining tool about its axis of symmetry, means for securing a blank, in which said volume is machined, having at least one degree of freedom in rotation, means for driving the rotation of said blank-securing means, means for securing a template, having at least one degree of freedom in rotation, means for driving the rotation of said template-securing means, a feeler capable of coming into contact with the exterior surface of said template, means for bringing about relative movement between said blank-securing means and said machining tool, and between said template-securing means and said feeler, said movement means allowing the machining tool and the feeler to remain in constant contact with, respectively, said blank and said template, means for commanding and controlling said means for driving the rotation of the machining tool, said means for driving rotation of the template-securing means and said movement means, wherein said machining tool comprises an abrasive disk and said movement means comprise a moving carriage on which said blank-securing means and said template-securing means are mounted so that they are free to rotate, said moving carriage having at least two degrees of freedom of movement.
