Today some edm manufacturers boast advertised first pass cutting speeds using large diameter coated wires in excess of forty inch hour which is a far cry from the twelve inch hour of the 1980s or the twenty inch hour of the early 1990s.
Wire edm cutting speed table.
Whereas the diameter of a cutting tool determines the offset in milling the edm controller applies a cutter comp based on the diameter of the wire.
The 0 016 topas h e a t.
Where wire edm is concerned accuracy has traditionally come at the cost of speed.
Repeatability and longer tooling life are must haves with component miniaturization and increasing production volumes.
The wire edm in figure 1 represents current technology.
Fast accurate electrical discharge machining.
The upv 3 wire edm machine was designed to produce the ultimate in precision machining while achieving ultra fine surface finishes.
Achieve the accuracy down to 2 µm machining repeatability with thermostabilization and finer surface finishes down to ra 0 08 µm essential to your daily success with the new cut p wire cutting edm series.
Most machines can cut tapers of 20 30 degrees depending on workpiece thickness.
For example if a 0 010 inch diameter brass wire is used the cutter comp will approach 0 005 inches plus a spark gap as the wire gets closer and closer to the part surface and possibly finish at.
Nc test cutting video of my home made wire edm.
He machine is built on the proven makino uj series wire edm platform that utilizes a stationary table design and is held to an even higher construction accuracy specification.
The α cib series comprises three versatile all rounders including the first model with an 800 mm table.
Moreover this increased power capacity allows the wire to cut efficiently at lower wire speeds relative to the feed rate.
The system consists of a.
The shape being cut is a cat figure again found from open clip art converted to dxf with inkscape and.
A typical 0 010 brass wire will break at higher power levels which is why standard wire edm generators typically top out around 30 amps.
That s why fanuc has developed a next generation robocut wire cutting machine.
Wire can take as much as 60 amps without breaking.
