Years ago we started using Hangsterfer's 5030 in the mill and after a few years we noticed the chips would stick on surfaces and a sticky residue would be left on surfaces. We just dealt with it and after a thorough clean up a year ago, we started to get the sticky issue again. Recently, I though about the production parts we started to run, just about the same time the stickiness started. These parts are pre-cut 6061, .750" square and 1.380 long. To date we have run about 3000 of these parts through the machine in three years. Last week I noticed the sticky stuff on a spot on the machine where we just started placing the stock before going in the fixture. Another thing that made me think of this is six months ago we switched to 5030 in the lathe and we do not see the sticky residue. The pre-cut stock doesn't have any visible residue on them but do feel a bit sticky when handled. I called the supplier of the pre-cut parts and found that they are using a seed oil based coolant in the saw. I am thinking that the seed oil residue is left on the stock and the Hangsterfer's washes it off and it gets suspended in the 5030 and deposits on the surfaces. It is not like way oil or anything like that. It tries sticky.
We are now pre-cleaning the pre-cut stock with detergent. We tried Dawn and Simple Green but it does not cut what we are assuming is seed oil residue as well as we would like.
So now to a question, what would be the best detergent and method to clean off the seed oil residue? Alcohol and acetone don't work that great. Goof-off works the best.
Try to imagine the lip on your container of linseed oil or poppyseed oil. It is that kind of sticky stuff. Or the oil residue that collects on the range hood after a month of cooking with olive and canola oil.
Does anyone else recognize this issue? I can't be the only one.
Thanks for looking and hope this helps others with this issue.
