Looped Diamond Fil / Kontinuèl Diamond Fil
Kounye a, se fil teknoloji koupe sitou itilize nan koupe materyèl difisil ak frajil tankou ingot Silisyòm, kristal, Meservey, ak seramik, e li gen yon bon pwospè devlopman. Avèk amelyorasyon nan sitiyasyon ekonomik entènasyonal yo, te endistri a en nan machin koupe fil antre nan yon wonn nouvo nan sik biznis, ki te pote sou ekspansyon nan demand kontinuèl mache dyaman fil, and the sales of the endless diamond wire cutting machine industry has rebounded significantly , The relationship between supply and demand has been improved, and the profitability of the industry has been steadily improved
The diameter of the commonly used endless wire is 0.65mm, and there are 0.4mm and 0.3mm under development. To grasp the characteristics of the loop wire itself, it can not be compared with the conventional open wire. Instead, it should be based on the cutting speed advantage to explore thinner wire diameter.It can be imagined that within a limited length, the smaller the wire diameter, the shorter the life of the wire. How to find the balance point between the life of the wire and the size of the cutting kerf is still a topic worthy of research.
Kounye a, many domestic silicon wafer manufacturers have used ring-shaped diamond wire/endless diamond wire cutting machines. For 158 × 158 polysilicon , it takes 5 minutes per cut, wire ‘s average serving life is 200 cuts, and some can cut 400 cuts.Endless wire cutting will gradually replacing band Saw machine to serve photovoltaic companies to further improve wafer production efficiency and reduce costs.
