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.

An electric motor that supplies power to the actuator for opening and closing the KF-21 canopy.

All units are equipped with a microprocessor-based MPCU controller that manages diagnostics, protection, and optional energy consumption monitoring systems. EAR rectifiers are trusted across ground support zones, hangars, and field operations.
