Įrenginys naudoja keramines, CBN arba deimantines šlifavimo galvutes su vandens aušinimu. Norint išlaikyti keraminio akmens formos švarą ir pastovumą, įmontuotas varomas deimantinis dresavimo diskas su automatiniu režimu. Dėl to užtikrinama stabili ir tiksli galandamos geležtės dantukų forma. Galandimo ciklą valdo CNC servo varikliai – tai leidžia užtikrinti nuoseklią pjūklo dantų dinamiką. CNC juostinių pjūklų geležčių galąstuvas NBS 300 turi integruotą aušinimo skysčio talpą ir purškimo sistemą, kurios padeda išlaikyti žemą geležtės temperatūrą šlifavimo metu. Kodėl mūsų galąstuvai yra išskirtiniai? 1. Trumpesnis nustatymo laikas 2. Taupomos šlifavimo galvutės 3. Tobula, tiksli pjovimo briauna ir geresnė medienos pjovimo kokybė 4. Pratęstas įrankių tarnavimo laikas 5. Problemos dėl profesionalios darbo jėgos ar operatorių? Dėl to galite nesijaudinti 6. Automatinio galąstuvo lankstumas Klodpfjyv D N Ijx Agfep
