Stainless steel jewelry production, wire-cut EDM

Are you curios to know how we cut steel pendents in stainless steel jewelry production?

Is there any alternative ? what are the advantages using wire cut in Stainless steel jewelry production?

How it effect the price and delivery time?

Read about one of the most used fabrication methods in stainless steel jewelry production.

The wire-cut EDM is electrical discharge machine that uses CNC controller and continuous-traveling vertical wire under tension as one of the electrode to produce the desired shape.

The wire in wire-cut EDM is about as thick as a small diameter needle which allows creating a very delicate parts or shapes. In the stainless steel jewelry industry this fabrication method mostly used to cut flat parts out of steel sheets i.e. dog tag pendants.

Wire cut in stainless steel jewelry production considered to be a slow fabrication methods.  As the industry advanced and if the thickens of the steel jewelry product we produce allowed. We prefer to use laser or plasma cutting. Which speed the process.

Another disadvantage of wire cut is the finish of the part edges. in most cases it will require longer and costly polish process.

Wire-cut EDM  Machining According to Wikipedia.org:

“In wire electrical discharge machining (WEDM), also known as wire-cut EDM and wire cutting, a thin single-strand metal wire, usually brass, is fed through the workpiece. The wire, which is constantly fed from a spool, is held between upper and lower guides. The guides move in the X-Y plane, and sometimes the upper guide can also move independently giving rise to transitioning shapes (circle on the bottom square at the top). This gives the Wire-cut EDM  the ability to be programmed to cut very intricate and delicate shapes. The wire-cut uses water as its dielectric with the water’s resistivity and other electrical properties carefully controlled by filters and de-ionizer units…”  [View Wikipedia Entry]

Wire-cut EDM Machining Process

Wire-cut EDM  machining also known as Electrical Discharge Machining is an electro thermal production process in which a thin single-strand metal wire in conjunction with de-ionized water (used to conduct electricity) allows the wire to cut through metal by the use of heat from electrical sparks.

Due to the inherent properties of the process, Wire-cut EDM  can easily cut complex parts and precision components out of hard conductive materials.

How Wire-cut EDM Works with stainless steel jewelry

Wire-cut EDM  machining also known as spark EDM  works by creating an electrical discharge between the wire or electrode, & the work piece. As the spark jumps across the gap, material is removed from both the work piece & the electrode.

To stop the sparking process from shorting out, a non conductive fluid or dielectric is also applied. The waste material is removed by the dielectric, and the process continues.
