Patent ID: 8800654

Claim:
A wellbore machining device for machining a tubular component of a wellbore, the wellbore machining device comprising: a control unit; and a down-hole tool unit connected to the control unit through a wire line, wherein the down-hole tool unit comprises: an elongated guide member, a tool member which is movably supported on the guide member and includes at least one machining tool supported on the tool member such that the machining tool is movable with respect to at least three axes of motion, a plurality of actuators controlled by the control unit and adapted to move the tool member and/or at least one machining tool thereof with respect to the axes of motion, wherein a first one of the axes of motion extends along the guide member, two anchor members each mounted to an axial end of the guide member and adapted to releasably clamp the down-hole tool unit to the tubular component, and a carriage guided on the guide member, wherein a plurality of machining tools are supported on the carriage and/or a plurality of machining tools are supported on at least one of the anchor members to be transferred to at least one of the devices of the tool member, wherein the control unit and the down-hole tool unit form a computer numerical control (CNC) device, and wherein the actuators are electric servo motors controlling an actual position of the tool member with respect to any of a path and a sequence of desired positions defined by the control unit.
