Before the high-speed machining center is used, it needs to be accurately tested with a precision detection device. Laser interferometers are often used for detection. Laser interferometers are an instrument that uses laser as a length reference to precisely measure the position accuracy and geometric accuracy of CNC equipment (such as machining centers and three-coordinate measuring machines). This equipment is recognized as a high-precision and high-sensitivity detection method, so it is widely used in the field of high-end manufacturing.
