Welcome to CNCexpo.com
This site is dedicated to CNC (Computer Numerically Controlled) Machines, associated equipment, and tooling. Without CNC Machine technology, the
cost-effective, automated manufacturing industry we see today would simply, not exist.
This picture represents robots in action. CNC Robots are just one of many
different types of machines in the CNC Machine world. Different CNC Machines
perform metal and other material machining, welding, assembly, measuring, and
other processes.
Life as we know it would be much different without CNC Machines. Travel alone
would not be as affordable, energy efficient, and comfortable as it is today.
As mentioned above, this site also represents equipment that support's CNCs. One
example would be a conventional mill that maintenance might use to make repairs
or parts for CNC Machines. There are calculators, bolt torque specification tables,
and conversion tables that encompass CNC, conventional, and maintenance usage
under the Shop Aids menu.
CNC Machine Components:
There can be many components, assemblies, and systems to a CNC Machine. Many of these components have both
electrical and mechancial parts. These components, are sometimes referred to as electro/mechanical devices.
This picture of an large multi-axis CNC Grinder has many components, assemblies, and systems that are needed
to perform it's tasks.
On the electrical end there are magnetic relay systems, servo motors, electronics such as the computer or
controller, probing systems to measure the workpiece or the machine itself, feedback devices for rpm, velocity,
position, temperature, pressure and force.
There are air conditioners to keep the electronics cool, chillers to keep the hydraulic systems cool, and chillers to
keep the coolant cool which in turn keeps the parts being machined and tooling cool. There are also ballscrews, gears, bearings, spindles, an automatic tool changer,
pneumatic, coolant, lubrication, and chip or other removed material recovery systems.
One more system to consider is the one that controls the environment that the machine is in. When extreme accuracy is required, the machine may have to be operated in a climate controlled room or building.
CNC Machine Tooling:
Tooling is another aspect of CNC machine components.
The importance of selecting the the proper tooling for the task at hand
cannot be understated for optimum precision and run time. Tooling in manufacturing is
where the "rubber meets the road". Success isn't just about the machine,
it's also about the tooling. The cutting tools, holders, fixtures, and all
the rest of the tooling is just as important as the machine. When the
tooling fails the machine goes down, production comes to a halt until
the problem is solved.
There are many tooling manufacturers that support CNC Machines. There
is a huge variety of cutters, holders,
fixtures, and other tooling. It is imperative that the tooling fits the
desired results. Many tooling manufacturers will provide free consultation
to help select the best tool for the job at hand.
Note: This site is being developed with the technical
expertise of people whom manufacture, operate, program, and maintain CNC Machines. It contains technical
information in the form of specifications, training, maintenance, calibrations,
use of precision measuring instruments, leveling and alignments,
shop aids, and software.
