We have developed a vacuum system capable of machining plastics, wood or aluminuim on our HAAS VF3 (18x36 table size).  It is capable of holding down anything form .030" to 3.0" thk material.  This process helps us eliminate about 70% of our setup time producing a much more competitive cost.  Another way for JD ELLEN MFG LLC  make your project come to life.
