[Jewel Blind Hole Rod]

Two types of rods:
1) Jewel rods(Material: synthetic sapphire/ruby)
Jewels rods are widely applied as survey pole to machine, survey and laser technology.
2) Ceramic rods (Material: zirconia, alumina, Sic, Si3N4 and optical glass)

Synthetic sapphire/ruby is wearable and anticorrosion, and it is in possession of very good thermal stability, chemical stability and nice optical performance. Jewel rod made of synthetic sapphire/ruby is generally used in high precision machines, super precision measuring and laser technology. Ceramic rod made of ZrO2/Al2O3 ceramic is generally used in medicine, high precision machines, high precision measurement, inspection, and laser technology, such as insert rod, measuring rod, laser rod, laser distance measuring instrument, laser control and guide instrument, and gyroscope. The jewel rod and ceramic rod are widely used in the environment which requires highly in the good performance of the anticorrosion, wearable, and heat exchange.



Outside Diameter of Ceramic Rod: Φ0.80 ~ Φ40.00mm, Max Deviation of Outside Diameter: 0.05 ~ 0.05

Length of Ceramic Rod: 1.00 ~ 5.00mm, Max Deviation of Length: 0.05 ~ 0.20

Outside Diameter of Jewel Rod: Φ1.00 ~Φ80.00mm, Max Deviation of Outside Diameter: 0.003 ~ 0.05

Length of Jewel Rod: 6.00 ~ 80mm, Max Deviation of Length: 0.05 ~ 0.20

Technical Index:

Material: Synthetic sapphire/ruby single crystalα-Al2O3, ceramic ZrO2, Al2O3, SiC, Si3N4, and optical glass, etc.
