To date, we have experience producing more than 10,000 pieces and have the ability to produce an average of 500 molds per year.

ORSKOREA’s centerless grinding machines ensure stable accuracy and durability without the need for chucks or centers. By allowing workpieces to rotate freely between the grinding and regulating wheels, they deliver high-efficiency and uniform machining for shafts, pins, housings, and other cylindrical components used in aerospace, defense, and advanced automotive systems. Key Advantages • High productivity through fast, efficient multi-part processing • ±2μm precision and long-term repeatability • Versatility to handle components from small to large sizes • Hydrostatic slides and spindles minimizing heat and vibration • Proven stability for high-value part manufacturing such as engine components, battery cases, and optical housings By combining productivity, accuracy, and reliability, ORSKOREA’s centerless grinders significantly enhance competitiveness in both defense and civilian applications.

Green Optics possess proprietary CVD-based Zinc Sulfide (ZnS) production technology for defense and industrial multi-wavelength optical materials. We have core technological capabilities to manufacture high-quality ZnS products tailored to meet diverse customer requirements. ZnS Material Optical Performance and Processing ZnS materials produced through CVD processes provide high transmittance exceeding 70% in the SWIR wavelength range (8-12 μm). When these materials undergo additional Hot Isostatic Pressing (HIP) treatment, the crystal structure undergoes recrystallization, improving transmission characteristics to achieve over 70% transmittance in the visible (VIS) wavelength range of 0.45-0.8 μm. This process extends the application range of optical materials previously limited to SWIR and LWIR bands, delivering superior optical performance across multi-wavelength regions from VIS to LWIR. Material Specifications: - STD-ZnS (Standard ZnS Material): Manufactured via CVD process, exhibits transmittance exceeding 70% in LWIR wavelengths (8-12 μm) with high physical hardness (Knoop hardness: 210 kgf/mm²). - MS-ZnS (Multispectral ZnS): Converted from STD-ZnS through HIP processing, extends wavelength range into the visible spectrum. While crystal structure recrystallization during this process reduces hardness somewhat (approximately 150 kgf/mm²), it still meets MIL specifications. This dual-processing approach enables comprehensive wavelength coverage while maintaining military-grade durability standards.
