5
axis cnc machines are used for a variety of
purposes. Large scale machines can be used to
mill automobile sized pieces, including models
for wind tunnels or casting. Smaller 5
axis cnc machines are also available, and these can save
time by reducing the amount of material repositioning
needed for 3D products. In
order to understand 5 axis units, it is necessary
to take a brief look at 3 axis machining.
A standard 3-axis machine operates in 3
linear axes of movement (x, y, z). These axes of
movement tell the tool where to begin and stop
each procedure, and could produce 3D engraving.
But if you wanted to machine the sides of the project
you would be forced to reposition the material.
 In
addition, 5 axis cnc adds two more axes of
movement (a, b). These two axes allow the cutting
tool to tilt so that the sides of the material
can be machined. The result is e.g. a cnc router
that can produce highly accurate 3D products
quickly and efficiently.
CNC
routers with five axis are ideal for
accurate, high-speed trimming, cutting, and
routing of wood, plastic parts, composites,
clay, and metals. These routers come in many
different sizes, ranging from garage sized
machines designed for making aluminum molds
to larger models designed for accurate cutting
and trimming of large aircraft parts and other
components. They are fully automated, and allow
the operator to input just a few commands to
produce many different pieces. These machines
can also help to trim and finish large metal
and plastic pieces with just a simple cnc software.
Who
uses a 5 axis machine
Because
a 5 axis machines typically takes up a great
deal of space, it is highly unusual to see
these machines in anything but the largest
shops and manufacturing plants. The high cost
of a 5 axis machine also makes it prohibitive
for users on a smaller scale. The
most typical users are
companies which need to produce large, one
piece products with shaping, carving, or finishing
on all sides. Plastics plants, aerospace factories,
automakers, and fabricators are just few examples
of industries which use 5 axis cnc technology.
