Holland Engineering Co.

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.

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.
