I am currently setting up a machine to drill holes in polished 304 stainless tube. This machine will make about 100,000 holes per year through one side of 3/4" by .060" tubing. To ensure long tooling life, I need to cool the bits. The tubing is prepolished and this is decorative stainless (so the appearance must be flawless after we drill). I am looking for a coolant that is easy to clean off the finished parts before they are assembled. Any one have any ideas?
BTW I am not tackling this project alone, I am working with Joe Agro Jr and his dad on this project. Also anyone one with first hand knowledge of good coolant pumps? I need one of those also.
Thanks in advance Greg Postma
