The scanning elements 3 are assigned to the illustrated hollow shafts bearing sleeves, their preferred embodiment presented as rollers and outer ends by means of a ring shoulder in a corresponding cutting tool 4 is pronounced as a face milling cutter Recess of the resiliently formed. The scanning elements 3 and the cutting supported shaft bearings and their inner 5 tool 4 are a common shaft 5,7 to-end areas arranged as sleeve-like bearing hubs, which are each in the lateral bearings 6 would take which is stored with an annular cylindrical approach for.

The support plate for the work can. In this case, 15 pieces 1 is denoted by "8" in one work step. The support plate 8 at the same time the two opposite one another has a recess 9 (F i g. 2) to remove the scanning weld beads, so that only elements 3 and the cutting tool 4 of the also thereby a substantial time saving direct device part to pass can be achieved. Another advantage of the invention is that each of the two hollow shafts 5 is made in two parts in that the profile surface forms next to the 20, the outer end of each being no longer attacked in a weld bead, so that bearing body 10 is inserted. At the inner end, the smooth surface of the profiles is expanded as far as possible, these corrugated parts are widened in the manner of a sleeve, which is retained. The great accuracy is due to the sleeve-like extension of the scanning elements 3, that even the local tolerance deviations are stored, namely with the help of an outer bearing of the profiles in the immediate vicinity of the 25 on the inner part of the sleeve and with an inner bearing weld bead through both sides the welding on the shaft 7, each of which is detected in the outer bearings 6 caterpillar-moving scanning elements, is mounted in this way (see FIG. 2). For the inner and outer load, the distance of the weld bead as far as the scanning elements are preferably used as small as possible, the actual profile surface near the needle bearing being built.
Welding point is adapted and also paragraphs or the like. 30 From FIG. 2 is also particularly clear which can be avoided because the shaft can be recognized by its double structure of the side bearings 6. The resiliently adjustable mounting at the ends of a non-rotating hollow shaft 5 are at their extremely good transition between two ends that deviate from one another in the bearings 6 in a bearing body 10 creating appropriate locations of the profiles. stored.
