ORSKOREA’s high frequency grinding spindles, operating at speeds up to 120,000 rpm—the highest level in Korea—are engineered for ultra-precision and durability in critical defense and aerospace applications. In addition to belt-driven, built-in motor, hydrostatic, and hydrodynamic types widely used in semiconductor and precision equipment, our spindles are customized to deliver the exact speed and power output required by customers. With over 25 years of expertise in repairing and retrofitting leading Japanese, German, and Swiss brands such as TOYO, KOYO, OKUMA, GMN, and Fischer, and with multiple proprietary patents including joint developments with Schaeffler Korea, ORSKOREA ensures proven reliability. These spindles are ideal for machining high-value defense components such as armored vehicle gears, drone actuators, aircraft engine parts, multispectral sensor housings, and advanced optical or communication devices, supporting the competitiveness of both defense and civilian manufacturers.

Our radars’ low-Size, Weight, and Power (SWaP) means ample room for other onboard sensors, such as Electro-Optical and Infrared (EO/IR) cameras. Users no longer need to decide which sensor to include and which to exclude. Instead, they can understand the bigger picture. Highly reliable, the NSP-3 has a recommended maintenance interval of 1,250 hours. It can gather data over land and maritime environments and can be used for applications as broad as sea ice monitoring and search and rescue, as well as specialized intelligence, surveillance, and reconnaissance (ISR) missions.

It is mounted on a weapon system such as a fuze that rotates at high speed, and is a high-sensitivity and high-performance GNSS receiver capable of providing up to 10Hz output and multi-band GNSS signal reception as well as narrowband jamming rejection capability. You can get more than 20dB anti-jamming capability comparing with traditional high-sensitivity receivers. Features: Mounted Anti-Jamming Algorithm High Sensitivity & Multi-Band GNSS(GPS/GLONASS/Galileo) Receiver Optimum Reception Even in Harsh Battlefield Conditions Currently Applying Weapon Systems such as Small Fuze

Lumir developed this new on-board computer in cooperation with Korea Aerospace Industries (KAI) for the CAS500-3 (technology verification satellite), which is scheduled to be launched aboard Korea’s fourth Nuri launch vehicle.

Large mirrors are crucial in various optical systems, particularly long-range multi-spectral setups for defense, surveillance, and commercial use, like UAV optics and agricultural temperature monitoring. Aerospace applications, such as satellites and telescopes, are common. These mirrors come in different shapes and materials, including Al, Si, Ge, and Cu, spanning visible, UV, and IR spectrums. By using advanced CNC grinding, polishing, and diamond turning we provide precise surface forms, with tight tolerances, and multispectral performance. Our mirrors, up to 700mm in diameter, provide impressive specifications: 0.05% radius tolerance, less than 0.5Fr P-V irregularities, 0.1Fr RMS at 0.633μ, and sub-40Å RMS roughness. MKS Ophir's proprietary coatings enhance spectral performance and surface durability. Contact us to set a meeting at ADEX Seoul

The L Series comes with frames in various lengths to accommodate a variety of module combinations. The frames range from a basic frame with just 2 side rails and 2 end caps, to more complex versions with jackscrews, backshells, cable clamps, etc.

Model-Based Systems Engineering (MBSE) is a methodology that integrates design, analysis, and verification activities throughout the system lifecycle using architecture models. By modeling requirements, functions, structure, and behavior, MBSE supports consistent and informed decision-making. Ansys SAM (System Architecture Modeler) supports the latest system modeling language, SysML v2, and enables both graphical and textual modeling, real-time collaboration, and model management. Ansys ModelCenter integrates various engineering tools and builds automated workflows, enabling what-if simulations and trade studies. By connecting architecture models with simulation models, it supports consistent design analysis and requirements validation using a single source of truth (ASoT).
