Jul 25, 2012· We make hardend and ground blanks for EDM shops. We as well heat treat our own parts to run on our wire EDM. All Tool Steel. It really does not make a difference. For us it just depends on all of our machining processes. Sometimes we have to machine after EDM and then heat treat. For your small parts I would heat treat before. Double temper for ...
EDM of Tool Steel Introduction The use of Electrical Discharge Machining (EDM) in the production of forming tools to produce plas-tics mouldings, die castings, forging dies etc., has been firmly established in recent years. Develop-ment of the process has produced significant re-finements in operating technique, productivity and
The surface roughness of a tool steel SKD11 machined by an EDM shinking with the difference type of electrode materials for the pulse current of 20A and 45A. Material Removal Rate The effect of the different type of electrode materials on the material removal rate from the tool steel . VOL. 11, NO. 2, JANU ARY 20 16 ISSN 1819-6608 ...
EDM or Electrical Discharge Machining is the burning/melting of the steel to form a tool or part. Proper heat treat of the steel is an ABSOLUTE MUST in preparing for the EDM process; 3 tempers minimum is required. When sinker EDM was introduced, the part/tool was made 1st and then heat treated after the EDM .

Mar 13, 2007· Instead, the key often is the machining processes used on the tool steel. A great deal of tool steel damage can result from improper machining procedures. Metal removal methods such as electrical discharge machining (EDM), drilling, milling, broaching, turning, and grinding all must be performed properly, or tool steel damage could result.
D2 Tool Steel. D2 Tool Steel is a versatile high-carbon, high-chromium, air-hardening tool steel that is characterized by a relatively high attainable hardness and numerous, large, chromium-rich alloy carbides in the microstructure. These carbides provide good resistance to wear from sliding contact with other metals and abrasive materials.
In this paper, work on machining by EDM for EN-31 grade tool and die steel has been presented. Although some literature on EDM of low carbon steels, carbides and die steels is available but all have emphasized on machining parameters. Not more has been mentioned on heat affected regions to

Cutting Tool Steel With Wire EDM. Difficult to machine materials, such as carbide, Inconel, D2 and A2 are as easily cut as cold rolled steel. The finished product is relatively free from burrs, the surface finish is excellent and there is minimal stress placed on the workpiece.
Dec 02, 2011· Although it's probably best to hang onto that grinder, jig borer or EDM your shop uses for cutting hardened steels just in case, milling those materials instead can provide numerous benefits when the process is understood and proper tools, equipment and software are in place. CTE
2.An experimental investigation for material removal rate in EDM using tool or graphite, copper and AISI 316. 3.Some investigation of Electrical discharge machining on OHNS steel with a copper and brass electrode to increase the surface finish and reduced heat-affected zone, lead time by .
Our EDM department operates 24 hours a day, 7 days a week. EDMs are typically used in tool and die production but have many other applications in manufacturing, aerospace and medical industries. Benefits of EDM machining include the ability to machine hard materials that are difficult to machine using traditional techniques.
EDM OF TOOL STEEL 4 Fig.1. A "rough-machined" EDM surface with a cross section through chips and craters. Material: Uddeholm Orvar 2 Microdized. The effects of the EDM process on tool steels The influence of spark erosion on the machined material is completely different to that of conventional machining methods. As noted, the surface of the ...
Historically, tool steels used for stamping and forming tools have included A2 and D2, with occasional use of the high speed steel M2. A2 and D2 are familiar to most tool builders and tool users as common, general purpose cold work tool steels.
Jan 30, 2017· For aluminum extrusion, these are usually made from H13 tool steel. A hole is first drilled through the die blank, (often also by EDM,) and the wire is then threaded through. The CNC moves the blank through the wire to cut the required profile. On modern wire EDM machines, the wire can be inclined to cut of shapes with tapered sides.
EDM of Tool Steel. Electrical Discharge Machining or EDM, as it is commonly known, is the process of machining tool steel through the use of an electrical current used to erode the surface of the tool. An electrical charge is passed between the anode, made of copper or graphite, and a cathode, the tool steel.
