In a method for manufacturing an annular scale from a measuring strip, the ends of a measuring strip are welded together, and the shortening of the scale-division marks in the joint region caused by the welding operation is compensated by a subsequent rolling operation.

Method for fabricating an annular scale

A scanning unit for a magnetic position measuring device is described. The scanning unit includes a carrier body having at least one recess and at least one bore hole in communication with the recess. A detector unit, having one or more detector elements and an electrical connecting lead, is arranged in the area of the recess. The electric connecting lead is disposed through the bore hole. A covering element, covering the recess and protecting the elements arranged therein against mechanical damage, is arranged over the recess. A filling material is provided in the remaining free areas of the recess under the covering element.

In a switching multi-coordinate probe an accurate and accurately reproducible switching behavior is attained by a plurality of seating points, which all have the same elasticity but also a relatively high stiffness. The bearing members (14) and their counterbearing support members (16) exhibit an adequate number of degress of freedom, in order to be able to accurately align themselves with respect to each other during assembly. After adjustment the contact zones of the individual bearing members (14) form with their counterbearing support members (16) circular lines, which all lie in one plane with respect to the stylus axis (FIG. 1).
