THK stands for ” Toughness,” ” High Quality,” and ” Know-how.” The company aims to contribute to the improvement of society and development of industry by focusing on these three principles in our technology development and product manufacturing processes. THK’s linear motion system enabled rapid improvements in the accuracy, speed and labor-saving potential of advanced mechatronic instruments. With THK‘s LM Guides, machine tools and industrial robots become capable of ultra-precise operations, and semiconductor-manufacturing devices can operate in submicron units. More recently, the system has been applied in liquid crystal manufacturing lines, railway carriages, assistive vehicles, medical equipment, skyscrapers and residences, and amusement devices. The use of LM Guides has truly expanded beyond all prior boundaries.
