Patent ID: 8332997

Claim:
A dental prosthesis manufacturing machine, comprising: first and second indexable turrets configured to be indexed about a common first axis, each turret having a roughing tool and a finishing tool, which tools are each configured to be driven to rotate around a respective corresponding rotating axis to machine a workpiece to form the dental prosthesis; a workpiece holder for holding the workpiece which forms the dental prosthesis; and a base supporting the first and second turrets and the workpiece holder, wherein the first and second turrets are placed on the first axis in such a way as to face each other, the workpiece holder moves along and rotates about a second axis intersecting the first axis, and the workpiece holder moves along a third axis perpendicular to the first and second axes such that the workpiece held by the workpiece holder is placed between the first and second turrets, the rotating axes of the tools each intersecting a plane formed by the second and third axes, and the workpiece is machined by alternately using the roughing tools and the finishing tools according to accuracy which is required when the workpiece held by the workpiece holder is machined.
