Holland Engineering Co.

United States

Holland Engineering specializes in CNC machining (computer-numeric-control machining). In CNC machining, the machine is programmed to do any of the jobs that would have been handled by conventional milling machines: cutting, turning, drilling, tapping, grinding, facing, knurling, threading, and the like. The result is that CNC machining can make complicated shapes with extremely high tolerance requirements, such as molds. CNC machining is also good for short runs.

Holland Engineering specialized in wire EDM (electric discharge machining). In wire EDM, a wire, ranging in thickness from .004 to .012 of an inch, acts as a charged electrode, while the material to be cut takes the opposite polarity. Sparks jumping the gap gradually remove material, while a stream of de-ionized water flushes away debris and acts as a dielectric fluid, controlling sparking. Wire EDM yields extremely accurate cuts with no burrs.
