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 SGU 35 cylindrical grinder is designed for precision grinding of cylindrical components in various sizes. It is particularly suited for aerospace and defense manufacturing, where high-strength materials and lightweight designs are essential. By delivering both durability and accuracy, the SGU 35 ensures reliable machining of aircraft parts, weapon system components, and other mission-critical applications requiring superior surface quality and long-term performance.

The SGTE/SGTI thread grinders are designed to machine both internal and external threads with high precision, accommodating diverse thread profiles and exact dimensions. These machines are essential for producing high-value components where accuracy and durability are critical, such as aerospace fasteners, defense system parts, and precision ball screws. By enabling shorter processes and greater efficiency, the SGTE/SGTI provide cost advantages in equipment investment and energy use. Developed as domestic alternatives to imported equipment, they strengthen localization efforts while creating new export opportunities in aerospace and defense markets.

The SGC 300 centerless grinding machine provides stable accuracy and durability required for defense and aerospace manufacturing. Its thru-feed design allows efficient machining of small cylindrical components without chucks or centers, making it highly effective for shafts, pins, and precision housings used in armored vehicles, drones, and aircraft systems. With in-house developed hydrostatic slides and spindles, the machine minimizes thermal distortion and ensures long-term repeatability, supporting the production of high-value parts such as bearing races, engine components, battery cases, and optical housings. By combining ±2μm precision with proven reliability, the SGC 300 strengthens the competitiveness of manufacturers in both defense and civilian applications.
