Cutting apparatus for ceramic green bodies

A method for cutting a green ceramic body comprising:

• providing an apparatus for cutting green ceramic bodies, said apparatus comprising:
• a traveling path for green ceramic bodies;
• supporting beds for supporting green ceramic bodies located at constant intervals in series along the traveling path;
• first and second arms, one on each side of the traveling path, the arms movable adjacent to the path for allowing green ceramic bodies to pass between the arms;
• first and second drive portions for moving respective first and second arms perpendicularly relative to the traveling path;
• a third drive portion for moving both arms in the same direction as the traveling path;
• first and second fine wire supporting portions on respective arms, each fine wire supporting portion having a servo motor with an axis of rotation-r a magnet member around the axis of rotation;
• a plurality of interchangeable and previously prepared fine wire winding bodies having a first rotatable bobbin, a second rotatable bobbin, and a fine wire having first and second ends, wherein each end of the fine wire is wrapped around a conical surface of one of the bobbins, said winding bodies mountable to, and dismountable from, the apparatus as a unit structure, wherein each bobbin is magnetically coupled for rotation about a respective axis of rotation by a respective magnet member, and said first and second ends of the wire extending between the arms for cutting a green ceramic bodies;
• and
• a traversing mechanism for varying a position where the fine wire is wound around the conical surface throughout the axial length of the conical surface;
• and
• moving the fine wire lengthwise for cutting a green ceramic body located between the arms.
