"Machine tool or similar machine with a slide that can be moved on gühranghahnen" »

In the case of machine tools, there is an increasing demand: »that the? Unrung tracks _} on which the sliding carriages of the machines slide» should be hardened and ground. Surface hardening of large workpieces presents some difficulties and is also relatively expensive. In addition, there is a risk of the workpieces being pulled out during hardening, so that the surface hardening of the webs has not yet been able to gain general acceptance.

To without surface treatment of the guide tracks To achieve hardened sliding surfaces even after all, steel strips have already been placed on the Pührungsbahnen, which with higher accuracy cold rolled are available. When cold rolling a compaction of the surface occurs, 30 that such steel strips have a very good hardness and are practically not susceptible to wear.

Drilling and milling work are often carried out on machine tools, "in which the tools are cut be cooled by supplied liquid. Ss lets then do not avoid that coolant gets on the slide ways and under the on the guide ways applied steel strips penetrates. As a result of the resulting corrosion, the steel strips are then pushed up, so that the guideways are no longer accurate and, as a result, the accuracy of the work on the machine is affected.

Me hiring avoids the cited Haeheil and creates a guide that also works with coolant working machines works flawlessly and has a long service life. The subject of inflation is one Machine tool or similar machine with one on guideways displaceable carriage, in which the sliding surfaces of the guide tracks are formed by applied steel strips are. The material part of the well-known steel band requirements becomes avoided according to the hiring that the steel belts at their! change by this opposite the guide tracks sealing strips are covered.

The seal between the strips and the edges of the steel strips can be achieved by interposing elastic strips. The desired success can also be achieved by spreading a conventional sifting compound

In the case of the guide example, a slide 2 can be displaced perpendicular to the drawing plane on a machine bed 1 * The slide 2 rests on three guide tracks 3 * 4.5t that are designed according to the firing. Said the three guide tracks correspond to one another in their design, only the middle guide track 4 is shown on a larger scale in FIG. On the guide track is a steel band 6, the bands of which are pressed by bars 7 on the guide track. The strips 7 are attached to the track by means of screws 8. They lie against the strips of the steel strip 6, preferably with the interposition of a sealing compound.
