SPINDLE UNIT FOR PRODUCING A HOLE IN A WORK PIECE OF FIBER-REINFORCED COMPOSITE MATERIAL

摘要

An apparatus for machining a hole in a work piece includes a spindle motor that is rotatable about a principal axis. The spindle motor includes a tool holder having a tool axis substantially parallel to the principal axis. The tool holder is rotatable about the tool axis. An axial actuator is configured for moving the spindle motor in an axial feed direction substantially parallel to each of the principal axis and the tool axis. A radial actuator is configured for adjusting a radial distance between the principal axis and the tool axis.
