CNC plasma
cutting machine is a familiar device for businesses in the mechanical industry.
Metal products processed by plasma cutting machines have superior quality than conventional
cutting machines. The following article helps you better understand the CNC
Plasma cutting machine and the notes you need to know when using it.
What is a CNC Plasma Cutting Machine?
When the
metalworking industry has not been widely applied, people often use Oxy-Gas
torch to cut and engrave high hardness material surfaces. However, this method
has a slow cutting speed, it is difficult to control and adjust the flame, the
quality of processed products completely depends on the skill level of the
worker. With these disadvantages, the Oxy-Gas method cannot produce machine
parts with small sizes and complex shapes.
The introduction
of the plasma cutter has solved this problem. Scientists have researched and
discovered that an inert gas path when passing through an electric arc will
create a high-temperature plasma beam. The plasma beam travels to the cutting
head, focusing on the surface of the material and igniting the metal in a short
time.
Computer Numerical Control
On the other
hand, Computer Numerical Control (CNC) is an automatic programming system
controlled by a computer. The CNC plasma cutting machine is a
device that works based on the digitization process, the automatic control
system will move the torch according to the pre-installed sample drawing on the
computer. As a result, this type of cutter can make the metal cutting and
engraving process faster but still ensure the accuracy of the final
product.
Plasma cutting
machines are often used to cut metal materials such as copper, stainless steel,
aluminum, black steel... In particular, this type of cutting machine is also
capable of processing metal with a thickness of more than 10mm with precision high.
Working principle:
The power supply
unit is activated which will activate the voltage and gas flow (without arcing)
to the cutting head. The spark generated from the arc starting circuit will
ionize and form a plasma arc. The high temperature of the Plasma arc transmitted
to the cutting head and exited to the outside will melt the metal, and at the
same time blow away the material from below the cutting groove. The cutting
head of the machine will move according to the pre-programmed drawing by the
CNC system.
Application of CNC plasma cutting machine
Outsourcing materials for the advertising industry
Automatic plasma
cutting machine can cut small and delicate details on billboards. Besides, this
type of cutter can also cut metal letters in any shape and size, meeting the
requirements of businesses and customers. Billboards are manufactured from
Plasma cutting machines with high aesthetics, cutting time is significantly
shortened compared to manual manufacturing.
Crafting kitchen utensils
Home kitchens or
industrial kitchens all use a lot of metal objects, especially stainless steel.
These products are often very demanding in terms of safety and usability. In
addition, the plasma beam from the small CNC machine is friendly to
human health, ensuring the creation of products that meet the above
requirements.
Production of art partitions, interior and exterior decoration
Fine art
partitions and interior and exterior decoration items often have complex
shapes, many sophisticated details, and need to use modern cutting technology
for processing. Popular products: Stair railings, art partitions, outdoor
balcony balustrades, elevators...
