The invention relates to a hand machine tool for the making of holes in an object (1) made of composite fibres, preferably with curved surface. The centre axis (7) of the hole (7) passes through a predetermined point on the surface of the object (1) and is oriented in a certain direction relative to the longitudinal direction of the fibres in a local surrounding of said point. The machine includes in combination a tool holder (4), rotating about its own axis (5) and a principal axis (6); a device (15, 18, 19) for adjusting the axis of rotation (5) of the tool holder (4) in the normal direction of the surface in said point; a device (32, 33a, 34, 35) for the axial feeding of the tool holder (4) relative to the object (1); a device (8, 9a, 21, 22, 23) for adjusting the distance (L) between the principal axis (6) and the axis of rotation (5) of the tool holder (4), and a device (15, 19, 20) for the taking up of forces and moments between the machine and the object (1) that originate from the making of holes, which forces rotate about the principal axis (6) and on one hand act in a direction that coincides with the axis of rotation (5) of the tool holder (4) and on the other hand act in a plane in the normal direction to said axis of rotation (5). |
