Claims

[Scope of utility model registration request]

A tool having a tool rotation driving means and a tool support member moving means, and which is rotatably supported by the tool support member in order to machine the inner wall of a hollow workpiece, is rotated according to the cutting allowance of the tool. A machine tool equipped with a numerically controlled tool support that corrects the position to the normal position by numerically controlling the support member moving means, which supports the hollow workpiece and moves forward and backward from the neutral position. a workpiece support that moves in a direction; and a tool holding member that is provided opposite to the tool support and holds the tool inside the workpiece in cooperation with a tool support member of the tool support. a clamping means for clamping and fixing the tool support when holding the tool; and a current limiting means for limiting the current to the tool support member moving means of the tool support when holding the tool. A machine tool equipped with a numerically controlled tool support stand.
