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.

ORSKOREA’s cylindrical grinding machines are engineered to deliver superior surface quality and tight tolerances for high-value parts. They are widely used in aerospace, defense, automotive, medical, and electronics industries for components that demand both strength and precision—such as engine shafts, landing gear parts, gears, and bearings.

Key Advantages
• Handles diverse, small-batch productions with consistent repeatability
• Exceptional dimensional precision for tight-tolerance parts
• Supports tapered and curved surface grinding
• Flexible workpiece capacity with swing up to 350 mm
• Smooth table movement with low noise and vibration for stable operation

By combining precision, versatility, and long-term reliability, ORSKOREA’s cylindrical grinders provide manufacturers with the performance needed to meet mission-critical requirements.

ORSKOREA’s thread grinding machines are designed for high-precision machining of both internal and external threads, covering a wide range of thread profiles and dimensions. These machines are critical for producing aerospace fasteners, defense system parts, precision ball screws, and other components where accuracy and durability are vital.

Key Advantages
• CNC Control: 4-axis (SGTE) and 5-axis (SGTI) for complex thread profiles
• High-rigidity structure minimizing vibration and thermal distortion
• Built-in dressing and balancing units for consistent quality

By shortening processes and improving efficiency, ORSKOREA’s thread grinders reduce costs while enabling high-value, high-accuracy production. They also serve as advanced domestic alternatives to imported machines, strengthening localization and export competitiveness.

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.
