Application example

Machine Doors


Sliding doors of CNC processing machines must close safely and work reliably. Their movement is mostly done by hand, which requires a smooth running. The door mechanism is exposed to temperature differences as well as to high humidity in the form of cooling water or cleaning fluid. Compressed air, abrasion and chips are further sources of interference with the door guidance system, which must be compensated for.

Linear solution used


Franke aluminium roller guides convince with smooth and quiet running even in rough environments. The stainless steel version is insensitive to moisture. The raceways are protected against coarse dirt by wipers. The large-size rollers compensate for smaller dirt and torsion of the machine housing.
