Machine Benefits

Qualitative Machine Benefits

• Revision in 2012:
• Replacement of main wearing parts: - all bearings of the 4 chucks on the track - cutting head itself - igus cable reel trays that run with the chucks
• Up-to-date machine control software (by ttm)
• Inspection of all moving parts loading/unloading (front and rear) - open everything, check, lubricate, replace, close
• Commissioning tolerance tests on all axes: - accuracy - repeat accuracy
• Tube transport (mandrels): the tube is carried in and out of the machining zone (cutting zone) by means of four mandrels: there it undergoes machining, also with the help of rotation and linear movement of the same mandrels. AŌer machining the tube is then transported to the rear unloading zone or unloaded in the central unloading zone
• Loading zones (there are two types of loading):
• Front loading, performed by five parallel chains for conveying the tube and four loading manipulators to liŌ and carry the tube into the area where it will be taken over by the mandrels
• Rear loading, (or bundle loading), where the tubes are stored in bundles and loaded one by one (by means of the same four manipulators handling the front loading) and brought into the takeover area to the mandrels.
• Cutting zone: the laser beam is generated inside a trumpf source (tlf 4000), with the use of c02, n2 and he. Successively it is guided by means of a number of mirrors to the of the head, where it shall machine the workpiece. Machining is obtained by a five axis (xm, ym, zm, a, c) laser system allowing for cutting in the whole space around the head nozzle. By using the auxiliary axes u, v, w and a1 the former ones can also work by interpolation between them, exploiting (also to keep machining down) rotation and linear movements of the mandrels. Distance between nozzle and workpiece is being constantly controlled by means of precitec capacitive sensor
