Wet milling in all it's glory!

WET MILLING e.Max To go with our video clip, here is a neat little article from IDT   about milling machines.  It explains a few basic workings and some comparative details - including wet versus dry. At Drake, we do both - different options for different configurations, different materials, and different outcomes.  If you want to know more, give us a call! You can never be armed with too much knowledge.
