Facilities Listing

Water jet  
  • 1- Omax
    •
  • 20 HP Jet machining center, 26" x 52". Omax JetMachining is a new concept in precision part production. The OMAX Center precision machines complex parts out of metal, plastic, glass, composites or ceramics at a very low cost. In only minutes, it can contour flat materials up to 2" thick - directly from a CAD drawing - to a dimensional tolerance within +.005 inch. It is ideal for short-run part production, just-in-time manufacturing, prototype part development and tooling.
