How to EDM Steel and Copper Alloy Simultaneously

2019/11/4Machining these materials separately requires multiple part setups (one for the tool steel and one for the copper alloy) and additional electrodes for separate burns with different EDM operations. This approach increases machining time for both electrodes' fabrication and EDM, which leads to higher manufacturing costs.

EDM Talks: Marc Sanders Discusses Best Practices When

Marc Sanders of Entegris | POCO Materials discusses the Nov. 2019 article "How to EDM Steel and Copper Alloy Simultaneously" (written by Marc and Rob Fothergill) with Graphel's Ken Dworznik. The discussion includes polarity, on-time, peak current, material choice, and more, with a focus on getting the best results for your EDM application on both steel and copper alloy.

EDM 101: Electrical Discharge Machining Basics

(It should be noted that Langenhorst did point out that you can use wire EDM to cut shims by stacking the stock, sandwiching it between two pieces of quarter-inch steel, and cutting off a stack.) However, if you're looking for a machining process that's accurate, precise and stress-free—at least on the workpiece—EDM could be just what you need.

Influence of process parameters in electrical discharge

2019/6/1Yan Cherng Lin et al. studied the impact of process parameters, including, I p, T on and gap voltage on MRR, EWR and SR in EDM of SKH 57 high speed steel with copper electrode material. Their study demonstrated that the MRR increased with the I p, and the maximum values were achieved at T on of around 100 μs, as the T on increased further, the MRR was reduced.

EDM DRILL

EDM (Electrical discharge machining) drills is also known as electric spark punching machine, small hole drilling and fast hole drilling and start hole drilling . Its working principle is to use the continuous up and down vertical movement of fine metal copper tube (called electrode wire) as the electrode to carry out pulse spark discharge to remove metal from the workpiece.

What is Electrical Discharge Machining and how does it

Brass, an alloy of cupper and zink, is often used for wire EDM or small tubular electrodes. Contrary to electrodes for die sinking, the wire used for wire EDM does not have to offer good resistance characteristics, as new wire is fed constantly duting the cutting.

Copper in architecture

Copper has earned a respected place in the related fields of architecture, building construction, and interior design. From cathedrals to castles and from homes to offices, copper is used for a variety of architectural elements, including roofs, flashings, gutters, downspouts, domes, spires, vaults, wall cladding, and building expansion joints.
