Electrical discharge machining, commonly called EDM, is used to create parts and components out of conductive materials that other machining operations cannot handle because of the hardness of the material, the precision of the required cut or other factors. EDM is used in many applications, but it is especially useful for creating prototypes, dies, and molds because it can cut very intricate pieces and cut through hard metals such as kovar, titanium, Inconel, carbide, and hardened tool steel. The medical, aerospace, automotive and defense industries use EDM machining extensively. EDM may also be used for removing drills and broken items from cavities. Micropulse has a complete range of EDM machines that will suit any customer needs.
Wire EDM (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.
The wire EDM machines at Fathom Manufacturing’s Arizona production facility are capable of cutting 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 radiance 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.

Ram / Sinker EDM machining uses a job specific electrode connected to the ram and the power source. As the head feeds into the metal to be cut, the metal erodes. The entire process takes place in a fluid bath that continuously flushes away cutting debris and cools the metal to prevent unwanted changes to its metallurgical properties. The Ram / Sinker EDM process can be used to clean and repair damaged exterior or interior walls with a .002” tolerance.
Ram/Sinker EDM, sometimes called cavity type EDM or volume EDM, uses specially shaped, graphite, copper or tungsten electrodes which is submerged with the workpiece in dielectric fluids. The electrode is connected to a power source attached to a ram or head, and slowly fed into the work piece. Which then creates a spark to sink or burn a shape into the material being machined.
Our Ram/Sinker EDM machines can be used to cut a wide variety of conductive materials, including precious metals, soft & hard metals, super alloys, and conductive ceramics. By using this technique rather than more traditional methods, Ram/Sinker EDM is able to produce complex shapes using 3D modeling without introducing stress or causing the machined material to suffer from heat distortion.

Practically Sharp .002″ Internal
What is the Work Envelope Capable by the Ram/Sinker EDM Machines?
Machine specs have limits, contact us to discuss.
What is the Production Size That Can Be Handled?
We can handle small to large production runs.
Small Hole EDM uses a specialized hollow electrode to cut precise holes into metal. The electrode spins, similar to a drill, but it is the electrical spark from the power source applied to the electrode that actually removes the metal. The process creates a series of holes in the material, which may combine into a single larger hole as the process continues. During the entire operation, the materials are washed with fluid to carry away waste and provide cooling. This process can create holes as small as .010 at any angle, with no burrs or damage.
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.

ALL angles are possible.
Is It Possible to Drill on Angles or Round Surfaces?
Yes, it is possible to drill on angles and round surfaces.
Can Small Hole EDM Remove Broken Bits or Taps?
Yes, and in most cases without harming the part.
CNC machining is fast for manufacturing prototypes and production quantity runs. CNC machines are programmable, and they can run autonomously, producing parts from a wide variety of materials quickly and efficiently. Micropulse West has a variety of state-of-the-art CNC machines to ensure we meet our customer needs for quality components.
A CNC lathe uses modern tooling and computer programming to create parts quickly and accurately. Parts produced on a CNC lathe are identical, making them ideal for applications that require precision. A CNC lathe has the same capabilities as a manual lathe, but it runs autonomously. Parts up to 11 feet long can be produced in large or small runs.
Our CNC gantry routers can create complex 2D and 3D parts and prototypes. The multi-axis machine’s bits spin at very high speed, following the specs from the computer program that controls the machine’s operation. We can create consistent parts with dimensions up to up to 5’ by 10’.
A CNC surface grinder creates parts with a fine surface finish. CNC grinders are semi-automated to provide more precise control for precision work such as sharpening blades or deburring cut pieces, with a tolerance of +/- .0002 / 6RMA finish. Multi-variable speed CNC surface grinders can handle a surface up to 12” by 24”.
Micropulse West by Fathom employs a highly skilled team of machinists dedicated to rapid prototyping. We use the full range of our CNC & EDM equipment to create exactly the part specified in your design. We offer fast turnaround and rapid changes as your design evolves. Multiple identical prototypes can be produced with a turnaround time of just a few hours.
Cutting surfaces on dies suffer from wear after a period of use, resulting in unacceptable finish or out of tolerance parts. Since dies are made from extremely hard materials to enable them to withstand the rigors of cutting other hard materials, they are difficult or impossible to repair in most standard machining facilities. We have the skills and equipment to offer complete die repair for all your tooling saving our customers time and money.
These machines use your computer generated designs and blueprints to create parts quickly and accurately. Our skilled team and the CNC programming controls speed, feed rate and pressure to control the finished product and ensure it meets your specifications exactly. We work with a wide variety of materials from very soft to very hard, turning out perfect parts every time.
The aerospace and defense industries include satellites, airline manufacturers, orbital spacecraft, NASA, Military and more. They require precise parts that are either not generally available to the public or they are in need of a number of unique parts and pieces for equipment. This means the parts these industries require have wide ranging needs and specs. On one side there is a need for mass produced parts, while on the other, there are unique spacecraft and rockets that may need small runs of very specialized parts.
The medical field often requires precise, accurate equipment created from materials that can be sterilized. Our EDM and CNC techniques are often the only way of achieving the tolerances necessary for the machined materials. A vast majority of what we do in the medical industry is medical device manufacturing for the tool, device or the custom equipment medical companies, as such, all parts and products used have to be perfectly calibrated and sized.
The automotive industry encompasses more than simply automobiles, it also includes the machines to build them, maintain them, and repair them. We machine the parts that these machines require to build, maintain and repair vehicles.
The automotive industry is one of the largest industries in the world. There are millions of cars sold every year, and every car requires very specific parts. Some of these parts are even unique to a particular make and model, requiring manufacturers to have small runs of certain parts made for the machines they use. Many prototype pieces are needed in order to test new models before they are made available to the public. Micropulse is able make the machine pieces necessary that the industry uses to build prototype car projects.
The energy sector is the backbone of society, providing electricity and other forms of energy to homes and businesses. The energy industry encompasses electricity, solar, natural gas, propane, and many other types of power. In addition to fossil fuels, many energy companies also have equipment for harnessing solar, wind, and water energy. As such, it requires parts and products that are very durable and dependable. As such we have machined many parts and projects in the alternative energy industry like green transit devices, solar conversion support, parabolic cells and molds.
