Of course, the machine can be delivered also in ready to use condition, incl . Control ( preferably Siemens ) etc. Description of modules Machine bed and Portal This assembly is made of steel profiles, wich are welded together. After tempering to reduce stress in the material it is filled with mineral casting. Then they are machined to finish accuracy. This material has up to 50 x higher vibration damping than steel , and a very high rigidity . It also features a very good thermal stability . Due to the good rigidity and vibration damping also a very good surface finish can be achieved . Also, the tool wear decreases drastically , thus results also high economy ! For more details please contact me ! Z - axis These parts are made of steel wich is welded together. After tempering they are machined to finish accuracy. Linear technology Here was not saved , as all forces are transferred to the machine frame trough these parts . So we are back to rigidity, vibration damping and all that goes with it ... Manufacturer: Schneeberger ( Switzerland ) Size: 25 Type: Ball Rail System ( Roller Rail System om request ) Accuracy class: G1 ( for high precision and lifetime ) Preload class: V3 ( high preload means high rigidity ) Ball Screws There are different variants . Not every application requires a high positioning accuracy... Standard ( included in delivery ) Manufacturer: FBT ( China ) Manufacturing process: rolled Diameter: 25mm ( 20mm in Z-Axis ) Pitch: 10mm ( 5mm on request ) Accuracy class: C7 ( 50µ / 300mm or +/- 25µ / 300mm ) Preload class: no preload Axial backlash: 30µ All ball screws have bearings on both sides . The fixed bearing consists of 2 angular contact ball bearings wich are preloaded. Optional ( on request ) Manufacturer: SBC ( Korea ) Manufacturing process: rolled Accuracy class: IT5 ( 23µ / 300mm or +/- 12µ / 300mm ) Preload class: 3% Axial backlash: 0µ Manufacturer: Korta ( Spain ) or Steinmeyer ( Germany ) Manufacturing process: precision ground Accuracy class: IT3 ( 12µ / 300mm or +/- 6µ / 300mm ) Preload class: 3% or 6% Axial backlash: 0µ Machine table The table is made of cast aluminium ( AlMg4.5 ) . This is enough for a machine of this size . If desired, they can also be made of steel ... The 6 T-slots are already milled and suitable for sliding blocks with M8 thread . All screws are sealed with plastic caps to ensure easy cleaning . Delivery time and payment according to agreement. Transport costs are just an example and may vary depending on the delivery address ! The price does not include VAT ( Value Added Tax ) !
