LEDs, medicine
R-axis, A-axis configuration
2,4,5,6,8-inch cylinders
Optimized cylinder cutting program
High crystal growth rate – 83 kg boule - in 15 days

We have achieved 55% of using of 83 kg of boule for cutting suitable blanks of 2 ”and 6” inch cylinders.
Total length for 2 ”blanks 5345 mm.
The annual total gross output of 2 ”cylinders (TIE) can reach 100,000 mm).
