Surion is evolving into a world-class helicopter The KUH-1, as known as Surion, is the multi-role utility helicopter. The Surion, complete with excellent maneuverability and a world-class hovering capability features cutting-edge avionics system. The copters have been deployed in the Republic of Korea Army(RoKA) for operation since the end of 2012 and carry out missions including troop transport, airfreight, contributing to strengthening military power. KAI continues to expand the scope of operation by development and modification of the military variants such as Amphibious for Marine Corps and MEDEVAC but also para-public uses for National Police Agency, Coast Guard, Firefighting and forest service and so on.

This miniaturized system allows, depending on the desired configuration, to move very precisely between 1 and 3 sets of lenses over a stroke of several centimeters. The design has been optimized to ensure perfect alignment of the lenses and to minimize their tilt throughout the movement. This optomechanical system mainly consists of high-precision standard MPS and FAULHABER modules, such as brushless or stepper motors, ground ball screws with double nuts and linear ball bearings. It is particularly recommended for focusing a laser over a long distance, for example for the guidance of unmanned flying objects or for communication between flying objects. The number of lens sets, lens size and stroke can be configured at will.

- Long life and precise movement control through fine-tuning - Shaft diameter 5mm~ - Accuracy G3~G7 - Shaft length differs depending on material, size, accuracy of shaft - Efficiency 85% or higher

Based on our state-of-the-art facilities, the semi-conductor machinery component sector manufatctures parts including Chamber assembly, and Main Frame Assembly.
