Discuri diamantate pentru tăiere uscată fină
- Acestea sunt utilizate cu precădere pentru a secționa plăcile de gresie și faianță, oferind o tăiere netedă, rapidă și fără așchii. Răcirea se realizează prin găurile de răcire special concepute.
CUM ALEG DISCUL DIAMANTAT?
Pentru o tăiere eficientă este important ca discul diamantat și materialul de tăiat să interacționeze corect.
Tăierea uscată utilizează aerul pentru răcirea lamei de diamant
În timpul tăierii uscate, operatorul trebuie să realizeze tăieri de adâncimi reduse pentru a permite aerului să circule în jurul lamei de diamant
În cazul tăierii uscate durata fiecărei operațiuni poate varia de la câteva minute până la câteva secunde, în funcție de duritatea materialului tăiat
Operatorul trebuie să efectueze tăieturi de mică adâncime, pentru a evita supraîncălzirea lamei discului diamantat
Atenție! Nu forțați lama discului diamantat în materialul tăiat
