Electrical Discharge Machining Services

Precision Machining Services is a world class provider of wire EDM and sinker EDM services. Our equipment and programming software give us the tools to complete complex projects with tighter tolerances and quicker turnarounds. Precision Machining’s wire EDM and sinker EDM services are ideal for machining extremely hard materials with tight tolerances, small internal radii and complex shapes that cannot be machined by any other method.

Our sinker EDM services can create imprinted shapes in metal in blind cavities, without cutting all the way through a part. Sinker EDM works by first creating an inverse of the desired shape out of graphite or copper electrode using our high speed mill, grinder, or other methods. We then “sink” that electrode into the construction material to create the part. Sinker EDM is ideal for mold making, creating shapes in very hard metals, and for creating threads and tapping holes in parts before heat treatment. It is also very effective in creating tight tolerance profiles.

Our Wire EDM services produce precision parts that match the dimensional tolerances of your designs within ± 0.0001”. With state-of-the-art wire EDM machining equipment and advanced programming, we can manufacture even the most intricate parts with perfect accuracy and repeatability, whether you need prototypes, short production runs, or quantities in the tens of thousands.

Our level of expertise in EDM services are unparalleled, and our variety of services is second to none. Contact Precision Machining for more information about our turning services.
