The Electrical Melting and Explosion(EME) process is
a heavy current non-contact electrical processing. During the
processing, a special electric interaction occurs between the
electrified tool electrode and the surface of the workpiece, which
causes a high density strong electron beam current, and this current
rapidly and locally melts, explodes and stripper the surface layer
of the workpiece, up to the processing criterion of the surface
roughness and the dimensional accuracy.
Technical characteristic :
 Conductive materials
regardless of hardness and stickiness can be processed by EME
machine tools, adapt to outside-circle cutting, inner-circle cutt
ing, level cutting, grooving or other type of cutting. The processing
material may be forged, stack welded or spray welded. The uneven
surface will not influence the processing efficiency.
The organization
of the processing material will not be changed. The surface will
not crack and function of the machine will not be altered. The
forged surface is just above the material surface by 0.05 to 0.33mm.
The processing efficiency
is high. The output of melting and explosion reaches ten to one
hundred and twenty kilograms per hour and the depth 0.01 to 15mm.
The productivity of rough process is promoted by five times while
the cost is reduced by fifty to seventy percent.
The machine tools
bear less force through adopting non-contact electrical processing.
The service life is five times longer than by traditional method.
The metallic material can be saved by fifty percent and power
of machine tools eighty percent.
The depth and precision
of processing can be controlled. The roughness of surface can
reach above Ra12.5 and precision ±0.05-±0.01mm, and the roughness
can reach Ra0.2.
F. Lighten working tension and improve working conditions.
Lighten working
tension and improve working conditions.
Easy to operate.
Without expensive
alloy cutter the process cost is low.
No environmental
pollution.
Consume less energy
in one to three times than by other traditional method. |
