Sinker EDM Application

Prototype production

The EDM process is most widely used by the mold-making tool and die industries, but is becoming a common method of making prototype and production parts, especially in the aerospace, automobile and electronics industries in which production quantities are relatively low. In sinker EDM, a graphite, copper tungsten or pure copper electrode is machined into the desired (negative) shape and fed into the workpiece on the end of a vertical ram.


Coinage die making

Master at top, badge die workpiece at bottom, oil jets at left (oil has been drained). Initial flat stamping will be "dapped" to give a curved surface.For the creation of dies for producing jewelry and badges, or blanking and piercing (through use of a pancake die) by the coinage (stamping) process, the positive master may be made from sterling silver, since (with appropriate machine settings) the master is significantly eroded and is used only once. The resultant negative die is then hardened and used in a drop hammer to produce stamped flats from cutout sheet blanks of bronze, silver, or low proof gold alloy. For badges these flats may be further shaped to a curved surface by another die. This type of EDM is usually performed submerged in an oil-based dielectric. The finished object may be further refined by hard (glass) or soft (paint) enameling and/or electroplated with pure gold or nickel. Softer materials such as silver may be hand engraved as a refinement.


Maintaining Cleanliness with Internal Machine Electrical Cabinets

No matter how clean you keep your shop environment there will always be very fine particulates of dirt, oil mist and other debris flowing through the air. These particulates can accumulate into just about any crack or crevice of a machine that has been under stationary operation for months or years. One critical area of an EDM machine that you want to avoid accumulation of debris is the electrical cabinet. If a machine's electrical hardware and connections become dirty, this can lead to potential performance and reliability issues. To combat this accumulation of debris, Makino designs its EDM machines with a sealed electrical cabinet design that keeps the electronic components and connections clean. This electrical cabinet design features a heat exchanger system that circulates air through a chamber inside the cabinet, but it does not introduce or blow any dirt, debris, or oil mist from the outside shop environment against the internal components. It's a subtle design feature, but critical to prolonging the life and long-term performance of the machines.
