To maintain your press brake there are several key elements to focus on, one of the most important being cleanliness. Dust and dirt are the enemies of your whole machine, especially your tooling. It is essential to keep your press brake wiped down and clean. Your machine should also have rust protectant applied to possible rusting surfaces.

Your back gauge needs to be kept clean to work accurately. Lubricate your rails and ball screws according to your manufacturer’s recommended schedule, but be sure to wipe off all excess lubrication so it isn’t collecting debris and other contaminants.

Your press brake’s electrical cabinets will usually have cooling fans or vent filters which can become blocked by dust, so they should be removed and cleaned or blown out at least monthly and as needed. Always keep the door to the electrical cabinet closed except when you are accessing it, both for safety and for cleanliness. The hydraulic pump motor should also be kept clean of dust and dirt.

Your press brake’s safety lasers must be kept clean in order to operate correctly. Any dirt on the lens can diffuse the laser, causing the light beam to spread out instead of being focused straight across. Scratches on the lens can also diffuse the laser, so be sure to use a clean, non-abrasive cloth to wipe off the dirt. It wouldn’t be a bad idea to have a specific cloth set aside that you clean the laser with every morning at start up to prevent any build-up on the lenses.

Another practice of good press brake maintenance is to keep the area around your machine clean as well. People always seem to have junk lying around everywhere in their shops and they tend to put things in places where they can get in the way. Keeping your work area clean can help prevent issues with safety and productivity, along with keeping dirt and dust away from your press brake.
