Don’t Gamble With Your Tools: Use Rust Protection

It’s a real heartbreaker to pull out a tool you haven’t looked at in a while and discover it has rust. Nasty stuff. I live within sight of the ocean, so my shop is particularly susceptible. That’s made me a believer in rust protection. Once rust sets in, we can clean it, but better if you never give it a toehold.

Best Practices for Preventing Collet Slip

Making Sense out of Tool Pull out Greg mentioned last week that we were putting the finishing touches on a report about collet slip. Why? It just always bugged us when we heard about it, as its been our strong belief that with a properly maintained system, pull out shouldn't happen. Its never been an issue in our shop in Waunakee, and it wasn't like we had some secret techniques we did here nobody else knows about. We just use common sense - keep tools clean and occasionally lubricate the drawbar. The fact is, with enough force, you can pull a tool out of a collet. But how much does it take? We designed our test to measure static pullout force of a tool from a TTS (modified R8) collet, and looked at a number of scenarios - not so much as a way to identify the absolute best method, but as a clear demonstration of how not to do things. [nggallery id=27] The test results validate what we always knew - if you properly prepare the mating surfaces and properly maintain (lubricate) the drawbar assembly, it takes alot - much more than the machine can actually pull up with. You're going to stall the spindle before the tool pulls out. You can read the entire report here, including a discussion of collets, test procedures, and data interpretation. Or you can skip ahead to the punchline and read the best practices recommendations below:
