    Aluminum cleaning

    Hello,

    looking for a best solution to clean laser cut aluminum parts. We have continuous orders for laser cut parts. Part size is approx 15 cm x 10 cm, it has several holes (diameter 8 mm). Batch is typical 200 - 400 pcs.

    Requirement for part finishing: "clean surface, no grease, no burrs, no sharp edges.

    Could you recommend what is the best method to make proper part finishing for such size batches?
    What is the best way to clean and degrease aluminum parts?

    thanks

    That finishing requirement is pretty much a standard notation on all drawings. If the customer is happy with the pieces as they come out of the laser then no further finishing is required.

    If not, then hand deburring and/or vibratory finishing might be required. Normally just some degreasing solution (liquid household cleaner) in the vibratory water is good enough. Another option for cleaning is a standard home dishwasher, I use mine for this all the time. There are commercial part cleaning systems, but for short runs it really makes no sense to spend that kind of money.

    Bottom line is that the customer sets the requirements.

    Usually, I use the Septone Metal Polish, but as Jim said, the dishwasher does a pretty job too. I don't use it that often, only once in a while or when I run out of the Septone, but if you're looking only for a clean surface you can work with that. When I have bigger projects I work with MaximaAluminium because I don't have such performant equipment but for the smaller projects, I work with my machines. Try this metal polisher, and I'm pretty sure there were other options similar to this. I like this one because it also protects from oxidation and this is an advantage too.

    Depending on the parts load there is a relatively inexpensive countertop residential dishwasher available. Set anywhere you have a sink and a countertop.

    We can use standard vibratory finishing process with plastic tumbling media cone 20mm (or 3/4 inches), the green colour XG recipe from Vibra Finish
    Tumbling time about 1-2 hours depends on your burr size

Found a nice lady on their website and in 3 hours she came and cleaned amazingly fast and well my garage where I have plenty of instruments, car/bike parts and so on. So she told me she used a little of vinegar and a washing gel (I don't know it's name).
    I was rushing at work and forgot to tell you all the story so here is my entire post
