Work processing apparatus

A work processing apparatus including

• a work table arranged facing a processing head configured to perform processing for a work piece and configured to hold the work piece,
• a table displacement mechanism configured to displace the work table in a direction perpendicular to an arrangement direction of the processing head,
• a table displacement mechanism drive apparatus configured to generate drive force for driving the table displacement mechanism,
• a table rotary drive apparatus configured to support the work table and the table displacement mechanism such that the work table and the table displacement mechanism are integrally rotatably drivable, and
• a control apparatus configured to control actuation of each of the table displacement mechanism drive apparatus and the table rotary drive apparatus, comprising:
• a drive source displacement apparatus configured to cause the table displacement mechanism drive apparatus to approach or separate from the table displacement mechanism to connect the table displacement mechanism drive apparatus to the table displacement mechanism or disconnect the table displacement mechanism drive apparatus from the table displacement mechanism, wherein
• the table displacement mechanism drive apparatus is connected to the table displacement mechanism while the table displacement mechanism determines a position of the work piece, and
• the table displacement mechanism drive apparatus is disconnected from the table displacement mechanism while the work piece is processed by the processing head.
