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.

The ACTUS® ARKS5255 (5-25X, 56mm FFP) Long Range Riflescope is designed for precision and durability, meeting the needs of professional users across a wide range of environments. Equipped with a First Focal Plane (FFP) optical design, it enables fast and accurate target coverage at any magnification level. The illuminated reticle ensures smooth and clear targeting in low-light conditions, such as during dawn or dusk. Whether in challenging operational environments or critical moments, the ACTUS® ARKS5255 is the ideal riflescope for users seeking superior performance when it matters most.

EO/IR Payload System EOTS (Electro-Optical Tracking System) is an electronic optical image tracking device that identifies danger and emergency situations on the battlefield, monitors and tracks tragets, and calculates their coordinates, and is an essential equipment for drones that can be used in both military and private sectors. M1 and M2 were developed to use a common mount that connects to the drone by keeping the size of the gimbal assembly the same at 4 inches. M1 can be recognized at a maximum of 0.2km for humans during the day and at night, and M2, which operates in adverse conditions at night, can be recognized at up to 1.0km for tanks in the form of IR continuous zoom.
