Wire EDM is one of the most accurate machining processes available. At Keystone, we can manufacture some of the most complex shapes with some of the closest tolerances available in the machine world.  With our two Sodick Wire EDM machines, our EDM specialists can produce both simple and complex parts with exceptionally tight tolerances and smooth finishes.  This capability allows us to combine with our milling and turning departments to produce parts that in the past would have been impossible to make at a cost that is extremely affordable.

Wire EDM can cut material of any hardness easily. Parts can be heat treated and stress relieved prior to Wire EDM allowing tight tolerances without distortion.  This feature allows  the construction of tools and fixtures in a high Rockwell range.

Keystone has the most advanced programming system available for its EDM department so that we can program both the top and bottom of the part to allow for land and taper, making it an excellent conduit for tooling and die sections.
