Laser equipment maintenance: Pay attention to cleaning the lenses and guides every day, sweeping up debris on the workbench; cleaning method for lenses: When cleaning lenses, it is necessary to use absolute ethanol or a cleaning solution containing 98% alcohol, use a small amount of lint-free cotton to lightly dab the alcohol and gently wipe the lens in a directional manner, and finally use a dry cotton ball to gently wipe the lens to make it bright and transparent; (Note that excessive force when wiping can easily scratch off the coating on the lens, causing damage to the lens) cleaning method for guides: First remove the stains and machining debris from the guides, then add a little clean lubricating oil to the guides, and move the sliding guides to ensure that the lubricating oil is evenly distributed on the guides. (Note that do not use too thick lubricating oil (grease) as this type of oil can easily adhere to the guides, causing machining debris and dust to stick, leading to wear and damage of the sliders and guides); cleaning method for the workbench: The workbench includes zinc iron alloy, honeycomb, crawler, blade strips, etc. First, clean the machining debris from the workbench. For crawler workbenches used for half a year, add a little clean anti-rust oil to the crawler and perform anti-rust treatment. Other workbenches do not require this. (Note that it is easy to rust if the workbench is cleaned with water, which can accelerate the oxidation of the workbench.)
