CNC EDM machines offer a wide variety of uses in industries
engaged in metalworking, fabrication, and manufacturing. These devices are the
next generation of machines, which can be used for cutting, drilling, milling,
grinding, etc. CNC EDM machines are frequently used in automotive making,
transportation developments, various medical fields, and building and
construction projects.
What are CNC EDM Machines?
CNC EDM stands for computer numerical controlled electrical
discharge machine. These devices were first created in 1976 as an off-shoot to
wire cut EDMs, which were patented in 1969. But compared to its forerunner, CNC
EDM machines offer better precision and efficiency in all metalwork cutting,
drilling, grinding, or milling processes.
CNC EDM machines became highly sought thereafter by
manufacturers who worked on metal tools and parts for its high precision. These
manufacturers include those in the automobile and aircraft industries.
Where Are CNC EDM Machines Manufactured?
This CNC device is produced across the US and in other
countries. Manufacturing companies that require cutting machines for their
projects can contact dealers of CNC EDM machines. In addition, a lot of
secondhand devices are also sold by their previous owners since they no longer
have use for these machines.
How CNC EDM Machines Work
In 1770, an English physicist name Joseph Priestly
discovered another use for electricity. If one aims it accordingly, one can cut
or erode metal, making electricity as a cutting tool. This is the underlying
principle of EDM machines.
In 1943, Russian scientists devised a machine, which stemmed
from Priestly's discovery. In 1969, an American mechanical engineer also
developed die or sink EDM and wire cut EDMs. It was in the 1970s that CNC EDM
machines were introduced and became popular among large-scale industries.
Equipped with a computer control panel, CNC EDM machines can
be programmed to perform a predetermined set of tasks. The programming process
will need an input of parameters regarding the dimension, shape, and hardness
of the metal work piece.
To begin the manufacturing and fabrication processes, these
elements need to be entered into the machine. After receiving these parameters,
the computer will send signals of information into the cutting electrode, which
will produce varying intensities of heat into the metal, cutting and eroding it
to produce the desired output.
Should you require a device to deliver your cutting,
drilling, or milling needs with absolute precision, you can rely on CNC EDM
machines to do the job.
Since the costs associated with CNC EDM machines are higher
compared to the conventional tools used for drilling, cutting, grinding, etc.,
you should make a preliminary assessment regarding your manufacturing needs and
your budget before acquiring these innovative devices.
EDM machines can play an integral part in your manufacturing processes. Speak to a reputable dealer for more information about CNC EDM machines.
