High-precision equipment

A high precision processing equipment comprising:

• a non-magnetic contactor provided in a numerical control processing unit and having a contact portion and first and second magnetic-electric converting elements at one end thereof;
• means for moving said contactor back and forth;
• a reference member made from a non-magnetic material and having a reference surface to which said contact portion of the contactor in its advanced position contacts;
• a support member forming a unitary body with said reference member to support a workpiece;
• and
• magnets attached to said support member in an opposed relationship against said first and second magnetic-electric converting elements and having interpole boundaries rectangularly intersecting each other.

A high precision processing equipment comprising:

• a processing unit rotatably supporting a spindle;
• at least two contactors provided in said processing unit and extending parallely with said spindle;
• means for moving said contactors back and forth;
• magnetic-electric converting elements attached to said contactors and opposed to said spindle;
• a magnet provided on said spindle so as to be opposed to the sides of the region of back and forth movement of said magnetic-electric converting elements and having magnetic poles aligned in the axial direction;
• a reference surface provided on a workpiece or its support member opposed to said processing unit to contact with said contactors in their advanced positions;
• and
• means for moving said support member toward a position for contact with said contactors.
