X-Sharp – Masini de ascutit scule stantare
Wilson Tool X-Sharp este o masina total automata de ascutit scule, usurinta procesului de ascutire permitand operatorilor sa programeze ascutiri regulate si de adaos foarte mic a sculelor- rezultatul fiind o durata de viata mult mai mare a poansoanelor si placilor de taiere. O investitie care se amortizeaza rapid prin economiile mari aduse prin prelungirea duratei de viata a sculelor si prin calitatea permanent buna a muchiilor pieselor d-voastra, calitate ce se obtine numai cu scule corect ascutite.

Masina are sistem de filtrare magnetic la circulatia lichidului de racire , nici o impuritate rezultata din rectificare nu ramane in lichid astfel incat filtrele normale se schimba mult mai rar fata de alte masini. Pe langa piatra (discul de rectificat) , se invarte controlat CNC si masa ce tine scule, combinatia de miscari duce la o calitate excelenta a muchiei. Masurarea inaltimii initiale a sculei se face automat . De altfel, operatorul are de selectat pe ecran doar tipul de scula si adaosul dorit de rectificat, masina adapteaza turatia, racirea si restul parametrilor la tipul sculei (nu se face rectificare cu aceeasi turatie ca la alte masini, turatia este adaptata automat la tipul sculei).
Reglarea usoara a adaosului de rectificare cu ajutorul controlerului touch-screen
Piatra (discul) este din CBN, un material excelent la rectificarea otelurilor aliate tratate specifice sculelor de stantat. CBN (Cubic Boron Nitride) este un material cu o duritate apropiata de diamant dar net superior acestuia la rectificarea otelurilor tratate specifice sculelor de stantare. Cateva informatii despre CBN (in engleza) mai jos :
What is CBN ?
CBN is an abbreviation for Cubic Boron Nitride, a development of the General Electric Company for which CBN was also registered, now it is a trade mark Diamond Innovations. CBN is still more costly than industrial diamond, originally the grain was much more expansive than gold. It is nearly as hard as diamond, almost 4 times as hard as aluminum oxide, and has revolutionized the grinding of hardened steel.
The wheels consist of a metal body which is coated in an electro-galvanic process with a layer of CBN-grain. The particles stick in a bond specifically designed for grinding without coolant. The CBN-grain is of a precise size, each one just a few thous.
Why CBN wheels?
CBN ist the best suitable grain for grinding hardened steel: You will hardly generate a high temperature, because CBN has an extremely good conductivity for temperature, so the heat generated is dispersed quickly. This is also helped by the shape of the metal body of the wheel. No more blues.
The wheels have an extremely long working life with an excellent rate of stock removal. The face will stay flat, no dressing and shaping necessary.
They will produce just the right cutting edge for turning tools.
Why not diamond wheels?
Diamond is chemically pure carbon. When it is used as a grinding grit it works extremely well with tungsten carbide or glass. With steel, this is a different matter: At comparatively low temperatures the diamond (carbon) forms carbides with some of the ingredients you have in every steel, nickel, chromium. That means the diamond is gone, your diamond grinding wheel is destroyed.
