WIRE EDM MACHINING

Wire EDM Machining Services


Wire EDM (A.K.A: Wire-Cut EDM or Wire Cutting) uses a thin single strand of spooled wire that is fed through a workpiece and submerged or flushed with deionized water. The deionized water constantly flushes away small particulates as the electrode cuts the material and maintains thermal stability. There is no physical contact between the wire and the machined part. The wire controls the path of the electrical discharge and as the wire voltage charges it removes layers of material with each pass.

Our Wire EDM Machines are capable to cut plates as thick as 16.5” and as thin as .001” which is usually accurate up to 0.0002”  and can have a cutting path or kerf as small as 0.006” and internal radiace of 0.003”. This helps with making punches, tools, and dies from hard metals that are difficult to machine with other methods.

Wire EDM services are perfect for projects that require the materials to be cut straight through or tapered. Since the hardness of the material being cut has no effect on the cutting speed, Wire EDM can be used to cut a wide range of conductive materials including hard metals or materials that are fairly brittle and would be damaged by other machining processes.

WIRE EDM APPLICATIONS

Wire EDM is used in many different industries to create small or large intricate cuts that require an extremely tight tolerance. It’s often used to create parts for the medical, aerospace/defense, firearm and automotive industries. Wire EDM can be used for any part that requires extreme precision but the utmost care.

WHY CHOOSE WIRE EDM MACHINING

There are a number of reasons why wire EDM is the best option for certain projects.

More-Effective-Cutting-Capabilities@1x

More Effective Cutting Capabilities

Wire EDM is more accurate than plasma, die, laser cutting or conventional tools. It is also a cost effective method for projects with low quantities.

Small-Radius-Cuts@1x

Small Radius Cuts

We can achieve small radius cuts that are not possible from conventional milling.

No Direct Contact@1x

No Direct Contact

There is no direct contact between the cutting tools and the part that is being machined. Leaving the machined part precise without any heat treat distortion.

Cut Many Different metals

Cut Many Different Types of Conductive Metals

Our wire EDM services can cut through many different types and sizes of metals, including kovar, titanium, carbide, and metals that require extreme care. These metals can range from thin and brittle to the incredibly thick and strong.

Cut Delicate Intricate Parts

Cut Delicate, Intricate Parts

Since no cutting forces are applied to the material Wire EDM services can also cut very small pieces, corners, internal fillets, and contours, which can be accurate up to .0002”. These shapes may be too delicate and intricate for other machining methods.

Prototyping up to High Volume Machining

Prototyping up to High Volume Machining

We can handle small prototyping projects which require quick turn around or high volume, large run machining projects requiring 24/7 production.

Surface finish achievable with EDM

Nov 16, 2017

Surface finish is often called out on part prints. Sometimes it’s because it influences appearance, more often because it affects how surfaces slide over one another. Bearing surfaces and those used for sealing are examples of where finish is important. An EDM surface finish is different to that produced by conventional machining. Cutting processes produce…

Let EDM be your secret weapon

Thin walls, tight internal radii, tapers, deep blind pockets in hard materials. Sometimes it seems designers are just trying to find the limits of what manufacturing can do. It’s as if they’re hoping manufacturing will say, “Can’t be done.” The thing is, if manufacturing only has access to conventional machining processes they’re probably right. Some…

How accurate is wire EDM?

Oct 4, 2017

It’s only natural that designers and toolmakers should ask about the precision of EDM. Knowing the capabilities of the process informs design decisions and influences costs. Whether the parts being made are surgical instruments, extrusion dies, or aerospace components, it’s important to know what tolerances are achievable. Unfortunately, there’s no simple answer. While accuracies of…

Wire EDM is Not Just for Tooling

You can think of wire EDM as the non-contact, 21st Century version of the fretsaw. A fretsaw is used to cut complex shapes from blocks of wood. The key to its versatility is the blade, which is essentially just an abrasive wire. Being thin and able to cut on all sides, the woodworker can turn it easily to follow…
