What are some tips that I can use to make my granite surface plate last as long as possible? Taking care of your surface plate well is incredibly useful when it comes to getting your money’s worth and making it last. You want to make sure that you keep your granite surface plate clean. Airborne particles like dust, water, grease, and other abrasive substances that are present in the manufacturing workplace can wear out your surface plate over time. Relatedly, whenever you are not using your granite surface plate keep it covered to help protect it. Rotating the plate periodically can also help ensure that no one area is being used more than another, resulting in more equally dispersed wearing. Perhaps most importantly, do not use your granite surface plate for purposes other than its intended use. It is not a table or workbench and you can avoid unnecessary damage by not using it as one.
