Edm Metal Cutting Machine

Edm is also known as spark machining and spark eroding.

Edm metal cutting machine.

As a result our cut off method produces highly repeatable lengths without end deformation distortion or delamination more economically than many competing methods. However for very high volumes of parts with diameters larger than 0 020 0 5 mm a method such as thin wheel abrasive cutting might be preferred. The process can be as simple as using a small diameter metal tube to cut a precise hole in a metal block to using a carved graphite block to machine a toy shape in a metal block for injection molding. For example a stamping die can be machined with 1 4 degree taper or a mold with one degree taper in some areas and two degrees in another with precision.

Edm machines shop for edm electrical discharge machining sinkers machines. Extrusion dies or nozzles and horns can be cut with constantly changing tapers. A wire edm machine is a type of cnc machine that can move along four independent axes to generate taper cuts. Edm electrical discharge machining is a way of cutting metal using electricity similar to a plasma cutter except under water.

The process is very common in manufacturing of injection molds. Modern edm machines with awt automatic wire threading and cnc capability can be programmed to work lights out to help mitigate the slow cutting speed. The wire which is constantly fed from a spool is held between upper and lower diamond guides which is centered in a water nozzle head.
