Lubricant performance hans stienbecker 01/11/2012 @ 5:15pm Excellent article Dave! I agree that making the right choice when it comes to lubricants is a confusing task. I have often seen that bad lube selection shuts down large and expensive systems costing big $$$. We had such a situation when we saw that our extrusion dies started wearing out much faster than expected. After some digging around, we ran some tests with the folks at ducom (www.ducom.com) and found our lube EP was no where near what it was supposed to be. We eventually installed their tester to control incoming quality. I feel that ensuring quality of that what goes into your machinery pays off in the long run.
