Welcome to Extreme Machining Extreme Machining is a fabrication, maching and waterjet cutting house based in Newark, Delaware. We specialize in precision cutting of all materials from thick to thin. Utilizing our two Flow waterjets or our MG plasma and oxyfuel table, we can cut any material to customer specifications. Our large 4 roll hydraulic plate roll can roll plate up to 1" thick, 10' wide. With our Haas CNC mill and lathes, we are able to provide customers with a finished product. We employ customer-friendly staff ready to give you the products you need for your business. In three years, we have grown from a humble 1, 200 square foot garage to a state-of-the-art 34, 000 square foot shop. Since its creation in late 2004 by Don Urie and Mark Kreshock, Extreme Machining has steadily gained employees and workspace. We can now deliver material orders to your location.
