Laser alignment is a precise technique used to ensure that machinery and components are correctly aligned. It involves using a laser beam to measure the alignment of shafts, pulleys, or other parts, helping to reduce wear and tear, improve efficiency, and prevent breakdowns. The process typically includes setting up a laser device that emits a beam, which is then reflected off targets placed on the equipment. By analyzing the beam's path, technicians can make necessary adjustments to achieve optimal alignment, ensuring that the machinery operates smoothly and effectively.
