Wire EDM

APM's Colorado machine provides Wire EDM (electrical discharge machining) services for use on hard metals, prototype production, small hole drilling, metal disintegration, and more.

Electric discharge machining (EDM), also referred to as spark machining, spark eroding, burning, die sinking or wire erosion, is a manufacturing process whereby a desired shape is obtained using electrical discharges (sparks). Material is removed from the workpiece by a series of rapidly recurring current discharges between two electrodes, separated by a dielectric liquid and subject to an electric voltage. One of the electrodes is called the tool-electrode, or simply the ‘tool’ or ‘electrode’, while the other is called the workpiece-electrode, or ‘workpiece’.

When the distance between the two electrodes is reduced, the intensity of the electric field in the volume between the electrodesWire EDM (Electric Discharge Machining) – Longmont Machine Shopbecomes greater than the strength of the dielectric (at least in some points), which breaks, allowing current to flow between the two electrodes. This phenomenon is the same as the breakdown of a capacitor (condenser) (see also breakdown voltage). As a result, material is removed from both the electrodes.

Once the current flow stops (or it is stopped – depending on the type of generator), new liquid dielectric is usually conveyed into the inter-electrode volume enabling the solid particles (debris) to be carried away and the insulating proprieties of the dielectric to be restored. Adding new liquid dielectric in the inter-electrode volume is commonly referred to as flushing. Also, after a current flow, a difference of potential between the two electrodes is restored to what it was before the breakdown, so that a new liquid dielectric breakdown can occur.

Applications



  • Prototype production

  • Coinage die making

  • Small hole drilling

  • Metal disintegration machining


Types of Mills:

  • Knee mill
  • Bed mill
  • Box mill or column mill
  • C-Frame mill
  • Gantry mill

Knee mill or knee-and-column mill refers to any milling machine whose x-y table rides up and down the column on a vertically adjustable knee. This includes Bridgeports.

This refers to any milling machine where the spindle is on a pendant that moves up and down to move the cutter into the work. These are generally more rigid than a knee mill.

Basic hobbyist bench-mounted milling machines that feature a head riding up and down on a column or box way.

These are larger, industrial production mills. They feature a knee and fixed spindle head that is only mobile vertically. They are typically much more powerful than a turret mill, featuring a separate hydraulic motor for integral hydraulic power feeds in all directions, and a twenty to fifty horsepower motor. Backlash eliminators are almost always standard equipment. They use large NMTB 40 or 50 tooling. The tables on C-frame mills are usually 18″ by 68″ or larger, to allow multiple parts to be machined at the same time.

The milling head rides over two rails (often steel tubes) which lie at each side of the work surface.
