Abstract: A precision machining apparatus includes a bite machining an object being rotated, according to a correction value, a fixing jig closely attaching the object to the bite and rotatably fixing the object, an optical unit magnifying and verifying a machining position on the object being rotated, a height control part controlling a height of the bite according to the machining position on the object, and an interval control part connected to an end portion of the bite and controlling an interval between the bite and the object.

Abstract: The present invention relates to a laser transmitter for simulation training, which is mounted on a firearm. The laser transmitter for simulation training includes an infrared laser diode 21 configured to emit an infrared laser beam, a laser beam shaping lens 22 disposed in the direction of travel of the laser beam of the infrared laser diode, a dichroic beam splitter 23 disposed in the direction of travel of the laser beam of the infrared laser diode and configured to have a first face 23a for transmitting an infrared laser beam and a second face 23b for reflecting a visible laser beam, a visible laser diode 31 configured to emit a visible laser beam and disposed at a position where the visible laser beam is refracted by the second face, and a focusing lens disposed in the direction of travel of the visible laser beam.
