Making Machinable Wax

November 25, 2012

I recently converted my mini-mill to CNC and watching it run full speed with aluminum is a little terrifying. I thought having some machinable wax to play with while I learn would save me a lot of anxiety.

After much searching on the interwebs I decided on a roughly 4:1 mixture of paraffin to LDPE. I decided to add some stearic acid and colorants so my final ratio was more like 4.5:1.

My recipe: * 1564g paraffin * 340g LDPE  * 47g Stearic Acid

Milling tests are going to take some time as it's in disarray at the moment.
