Abstract: Provided is a work processing apparatus configured so that limitations on the contents of processing for a work piece or the type of work piece can be reduced and processing for a wider range of processing contents and work piece can be performed. In a work processing apparatus 100, a work table 101 is, through a table displacement mechanism 103, supported on a rotation base 120 to be rotatably driven by a table rotary drive motor 125, and a weight holding tool 110 is supported on the rotation base 120 through a weight displacement mechanism 114. The table displacement mechanism 103 includes a rack-and-pinion mechanism configured to displace the work table 101 in an X-axis direction as viewed in the figure. At the table displacement mechanism 103, a power inputter 108 configured to input drive force from a table displacement mechanism drive apparatus 130 is provided.
