Capabilities
   EDM Electrode / Wire Type:       
   Your choices are...         
   Electrode Materials       Graphite, copper, tungsten, tungsten-copper, brass wire or other raw stock materials used to form EDM electrodes. 
   Drilling / Tube Electrodes       Solid rod or hollow tube shaped electrodes for drilling or trepanning applications.  Tube shaped electrodes with a single bore or multiple bores for drilling or trepanning applications. 
   Letter/ Digit Electrodes       EDM electrodes prefabricated with letter, number or symbols configurations. 
   Tapping Electrodes       EDM electrodes prefabricated for EDM machining of female or internal threads. 
   Ram / Sinker Electrodes       Custom electrodes designed for CNC ram or sinker EDM machining applications for dies, molds or specialized parts. The ram electrode has a three dimensional configuration that is "sunk" into the surface to create an imprint or a cavity of this configuration in the machined workpiece.  Cavities, thin walls and extremely fine features can be machined into a part or mold using EDM electrodes. 
   Wire       EDM wire is used in traveling wire EDM machines.  EDM wire does not need to have the EDM wear or arc erosion resistance because new wire is continually fed during the EDM wiring cutting process. 
   Coated Wire       Coated wire has an outer coating of zinc for improved corrosion resistance, spark formation and flush characteristics. Coated wire is sometimes called "speed wire" due the increased metal cutting rates the material provides. 
   Other       Other, unlisted or specialized electrode type. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Tooling and Consumables       
   Your choices are...         
   Dielectric Fluid       The dielectric fluids perform three functions:
  • Conducts the sparks by breaking down at the appropriate applied voltage
  • Acts as a workpiece and electrode coolant
  • Flushes away the eroded debris or EDM chips
 
   Electrode Holder       The EDM electrode holder should securely clamp onto the electrode with a high degree or precision and repeatability.  The tooling system should also allow the electrode to be redressed or machined on standard mounting plates or shanks. 
   Fixture / Workholder       Clamping device or system designed to hold the workpiece with the proper orientation, positioning and clamping pressure to ensure accurate machining. 
   Guide / Ferrule       EDM wires or electrodes are fed through and guided by the ferrule, which is usually fabricated from ceramic. 
   Inhibitor / Cleaner       Inhibitors and cleaners are added to the dielectric fluid to clean and prevent corrosion of workpieces and components.  Cleaner remove or prevent the build-up of lime, calcium, erosion sludge and other deposits.  
   Other       Other unlisted or specialized consumable type. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Material
   Material       
   Your choices are...         
   Brass       Brass materials are used to form EDM wire and small tubular electrodes.  Brass does not wear as well as copper or tungsten, but brass is much easier to machine and can be die cast or extruded for specialized applications.  EDM wire does not need to have the EDM wear or arc erosion resistance because new wire is continually fed during the EDM wiring cutting process. 
   Carbide       Carbides are compounds of a metal or metalloid (B, Si) and carbon. Metal carbides are also known as hard metals such as tungsten carbide (WC), titanium carbide (TiC) or tantalum carbide (TaC). Metal carbides have high hardness and high melting points. Metal carbides often used a cobalt, nickel or intermetallic metal bond between grains (cemented carbides) which results in increases toughness compared a pure carbide or ceramic.   
   Copper       Copper has better EDM wear resistance compared to brass, but the material is more difficult to machine than brass or graphite.  Copper is also more expensive than graphite.  Copper is useful in EDM machining of tungsten carbide or in applications requiring a fine finish. 
   Copper Graphite       Copper graphite is more expensive, but the material has improved conductivity and flexural strength compared to pure graphite.  The higher strength is useful for fabricating thin section EDM electrodes. 
   Copper Tungsten       Copper tungsten materials are composites of tungsten and copper produced using powder metallurgy processes. These materials very expensive compared to other electrode materials.  Copper tungsten is useful in making deep slots under poor flushing conditions and in EDM machining of tungsten carbide. 
   Graphite       Graphite is the most common EDM electrode because of its good machinability, EDM wear resistance and low cost. Graphite is a form of carbon (C) with an anisotropic hexagonal crystal structure.  Graphite or carbon is a non-metallic element with an extremely high sublimation temperature, which provides resistance to high temperature arcs.  Fine grain sized graphite tend to have better erosion and wear performance, but higher cost.  
   Molybdenum       Molybdenum is used to make small hole EDM electrodes and EDM wire for specialized applications. Molybdenum is a refractory metal with good strength and arc erosion resistance due to the metal's high melting point (2610oC).  
   Tellurium Copper       Tellurium copper is useful in EDM machining applications requiring a fine finish.  Tellurium copper has machinability similar to brass and better than pure copper.  
   Silver Tungsten       Silver tungsten materials are composites of tungsten and copper produced using powder metallurgy processes. These materials very expensive compared to other electrode materials.  Silver tungsten is useful in making deep slots under poor flushing conditions and in EDM machining of tungsten carbide. 
   Tungsten       Tungsten is a refractory metal with elevated temperature strength.  Tungsten has a high melting point (3410oC) and high resistant to arcs (low EDM wear), but also low conductivity. Tungsten's brittle nature and high melting point often results in fabrication using grinding or powder metal techniques.  
   Tungsten Carbide       Tungsten carbide (WC) materials are compounds of a tungsten metal and carbon usually with a metal binder.  Metal carbides have high hardness and wear resistance, which makes them useful for EDM electrodes, wire guides or ferrules and other wear applications. Metal carbides often use cobalt, nickel or other metal bonds between grains (cemented carbides), which results in increases toughness compared a pure carbide or ceramic.   
   Other       Unlisted or specialized cutter material. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Fine / Ultrafine Structure?       Fine grain sized structures tend to have better erosion and wear performance.  
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Electroformed?       Electrodes machined or formed through an electroforming process. In electroforming, a thin layer is plated onto a removable pattern often made of wax.   Thin shell electrodes can be manufactured with this technique.  
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
