Abstract: A method and apparatus for measuring a hole depth in a composite-material workpiece machined by a orbital cutting tool, including the steps of applying a low-level electric potential to an electrically insulated cutting tool having a cutting head with radial and axial cutting edges and with a predetermined axial length; determining a first zero reference position as the cutting tool initially contacts a first surface of the workpiece and closes an electric circuit through the grounded workpiece; and detecting a second reference position when the cutting head penetrates an opposite, second surface of the workpiece. The finished hole depth is determined by deducting the predetermined axial length of the cutting head from the total length of axial advancement from the first zero reference position to the second reference position. The orbital machining apparatus includes ceramic bearings electrically insulating the spindle and the cutting tool from surrounding components of the apparatus.

Abstract: A device (12) for detachably fixating a portable drilling machine to guide holes in a template includes a sleeve (20) having a substantially cylindrical portion to be inserted into a guide hole, and an expansion member (26) with a lever (34) extending radially from an axial portion thereof.

The expansion member (26) is biased by a spring (44), via the lever, towards a locking position in which all three contact sections (24, 32) may engage the wall surface of the guide hole so as to fixate the drilling machine to the template.

The method comprises the steps of positioning the longitudinal center axis of the cutting tool at an angle, which is offset from a normal to a flat surface of the workpiece such that the inclination of the longitudinal axis of the cutting tool substantially corresponds to the desired inclination of the wall of the conical hole to be formed, rotating the cutting tool about its longitudinal center axis, moving the cutting tool in a circular path about a principal axis corresponding to the longitudinal center axis of the hole to be machined, and feeding the cutting tool in its longitudinal direction towards and into the workpiece.

Abstract: A clamping chuck having a central receptacle and a disk arranged around the receptacle and which may be moved from a clamping position, whereby a draw bar inserted into the receptacle is clamped, to a releasing position wherein a draw bar is released from being clamped. The disk has a locking mechanism including a plurality of locking elements which are equally spaced in a circumferential direction. The draw bar is coupled to a brake such that the braking force of the brake is proportional to a pull on the draw bar. Thus, a high axial load on the draw bar causes a high braking force and a low load results in a low braking force.
