EDM Machine Services

At M.A.R.’s we provide Wire EDM machine services. With the ability to cut/burn though any conductive material with Tight tolerances and near perfect repeatability, we leverage our EDMing capacity in several ways. The First and most obvious way is by be ability to manufacture parts that require wire EDMing completely in house. The second and more common way in w we take advantage of this capability in being able to make specialty tooling in house.

The use of the EDM for custom tooling allows us to engineer custom cutting tools for each part which results in faster cycle times with extra accuracy and and consistency. With this tool making being “in-house” we are able to make new or updated tools with next to no lead time at a very low cost. The Low tooling cost paired with the faster per piece cycle time leads to a lower cost of production with is passed on to our valued customers!

Precision Geometry for Complex Profiles

Wire EDM supports intricate outlines, sharp internal corners, and detailed features that cannot be produced with conventional cutting tools. Because the process uses a continuously fed wire and electrical discharge rather than mechanical force, it maintains accuracy on components with thin walls, tight radii, or intersecting geometries. This capability is especially valuable for parts that require consistent dimensional relationships across multiple features.

Dimensional Stability for Hard and Exotic Materials

EDM machining is well suited for materials that are difficult to cut using traditional methods. Hardened steels, tool steels, carbide, and other high strength alloys can be processed without inducing stress, heat distortion, or micro cracking. This allows M.A.R.’s Engineering to support components that must maintain structural integrity and surface quality even after significant material removal.

Surface Integrity and Edge Quality

The EDM process produces clean edges and uniform surface finishes that support downstream assembly and functional performance. Because the cutting action is non contact, the process avoids burr formation and eliminates the need for aggressive deburring or secondary finishing. This is especially beneficial for tooling components, precision inserts, and parts that require consistent surface conditions for proper fit or alignment.

Programming Flexibility for Specialty Tooling

Custom tooling often requires unique geometries, controlled clearances, and precise alignment features. EDM programming supports these requirements by allowing the wire path to follow complex contours with minimal setup changes. This flexibility enables rapid development of new tools, quick revisions during part optimization, and efficient production of specialty fixtures that support high volume machining.

Integration With Multi Machine Workflows

Wire EDM is frequently used to complement screw machining, CNC turning, and CNC milling. By producing accurate tooling and precision features that are difficult to achieve mechanically, EDM machining enhances overall production efficiency. Components that require tight tolerances, fine slots, or detailed cutouts can be finished on the EDM after bulk material removal is completed on other platforms.

EDM Machine FAQ

What Types of Parts Benefit Most from Wire EDM Machine Services?

Components with intricate profiles, sharp internal corners, or tight tolerances benefit from the accuracy and non contact cutting action of EDM machine services.

Can EDM Process Hardened or Difficult Materials?

Yes. Hardened steels, carbide, and other high strength alloys can be cut without stress or heat distortion.

How Does EDM Improve Custom Tooling Production?

The process allows precise, repeatable geometries to be produced quickly, supporting faster cycle times and reduced tooling costs.
