How to maintain your metal pressbrakes?
To maintain your press brake there are several key elements to focus on, one of the most important thing is cleanliness. Dust and dirt are the enemies of your whole machine, especially your pressbrake tooling&auto cnc pressbrake back gauges. 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 ball screw&linear guide sheet bending 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, some pressbrakes manufacture offer cnc auto lubrication, which you need to make sure have enough oil in tank.
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, this is is very important when you fill oil to tank, you need to clean fully the tank, everytime you change the oil, you should be clean the tank before filling fresh oil.
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 metal bending machines area clean can help prevent issues with safety and productivity, along with keeping dirt and dust away from your press brake.
Cleaning Press Brake Tooling for Your sheet metal bending machines
When you bending sheet mteal material on press brake, you cause mill scale to flake off of your material, particularly when you are working with black iron. Regardless of what material you are bending, dust and debris will come off of the metal and will work its way down under your pressbrakes dies. Even if you are bending aluminum&stainless steel, there are fine particles along the cut edge that will break off. Any material coatings, rust-proofing chemicals, and built-up resin will also flake off during bending.
All of these factors are continually building up in and around your tooling, getting compressed and stuck to it. If you aren’t changing your tooling often — or even if you are, but don’t clean it in between using different bending tools — you can significantly affect the accuracy of your press brake, as metal bending accuracy will be got according to different match of upper punch and lower dies. For example, if enough dust collects to change your press brake tooling height , you might get the accuracy of your bends by as much as two degrees difference..
Wiping oil — which can collect dust — and mill scale off of your tooling as you are changing it can make a huge difference in the long run. Besides cleaning the working surfaces of the tooling, you should also clean underneath your bottom die and wipe off the top part of your upper punch (where it seats to the machine). It is also a good idea to keep your tooling clean to sight on the exposed surfaces as you are using it.
So clean your pressbrakes and make your pressbrakes get higher bending accuracy and long using life!
