B Series incorporates the highly reliability Hypertac® hyperboloid contact which provides optimum performance in harsh conditions such as extreme mechanical shock and high mating cycles.

The SNT motif motor business is divided into powertrain parts, electric provision parts, and convenience motor parts. Based on our diverse experience in the global market, we are supplying eco-friendly motors, which are key components of hybrid and electric vehicles.

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.

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
