Typical Applications
These precision motion components are widely adopted across electronics, automotive, semiconductor, robotics and medical-equipment industries. For example:
• In CNC machining centers or precision presses, a THK linear guide enables stable movement of tables or tool holders under heavy loads and high accelerations.
• In automation or robotic systems, the guide ensures accurate motion of actuators, grippers or transfer units with minimal vibration and deflection.
• In semiconductor or optical manufacturing, where micro-positioning is essential, the LM Guide supports stages or alignment mechanisms requiring repeatable movement and very low error.。
