SMALL HOLE EDM MACHINING

Small Hole EDM Machining Services


We use computer-controlled Small Hole EDM machines in order to carefully cut holes in a wide variety of conductive metals and materials. Small Hole EDM is different from Wire EDM in that it is mainly used to cut small holes in passes, rather than cut pieces of metal into shapes.

Small Hole EDM is the process of using a hollow electrode that spins around a spindle, similar to a drill and drill bit, and uses the small hollow electrode to guide the electrical pulses through metal. The electrode is made of either brass or copper tubing and is electrically charged by a servo-controlled generator producing the spark.

Since the holes are cut via guided electric spark, and not by the electrode itself, this leaves the conductive material free of burrs and other deformities. Small Hole EDM is also effective in simpler applications, such as removing broken taps & drills from cavities.

SMALL HOLE EDM APPLICATIONS

Small Hole EMD is used in the aerospace/defense and automotive industries for an example to create small coolant holes in tooling, taps, end mills, drills and its ideal for injection nozzles which is too difficult to drill using other techniques

WHY CHOOSE SMALL HOLE EDM MACHINING

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

Small Holes In Hard Materials

Small Holes In Hard Materials

Our small hole EDM services can make small holes in hardened materials like carbide & tungsten.

Reach Inaccessible Areas

Reach Inaccessible Areas

Holes can be created in pieces or finished products that could not otherwise be drilled. This allows for the placement of holes in very small or inaccessible areas.

Uses Less Force

Uses Less Force

Small Hole EDM uses very little force to create holes. Instead, the material is gradually eroded by repeated sparks.

No Burrs Or Damage

No Burrs Or Damage

The method used to create the holes in the material leaves no damage. There are no burrs or other dents around the created holes.

Small Diameter Holes

Small Diameter Holes

Each system can be set to automatically create the necessary holes in the material. We are capable of manufacturing holes down to .015”.

All Conductive Materials

All Conductive Materials

Our Small Hole EDM services can handle any type of conductive material, whether it is hard metals or soft brittle materials.

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

Oct 26, 2017

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…
