CNC Precision Machining Information

CNC precision machining can provide ultra precise measurements on any type of job and for any type of product, part, etc. The more axes that the machine operates on the better the results are for precision. Most of the time, the best precision capabilities comes from the CNC 5 axis machines.

A five axis CNC machine offers a wide range of possibilities for any shop. These machines can create basically anything imaginable, even a replica of the human head. Most machines operate on two or three axes; however, 2D and 3D effects are all that can be created. The five axis machines offer so much more. You can create the hardest angles, closets cuts, etc.

Five axis machining offers a tolerance range of 1 micron (0.000039") to 100 microns (0.003937"). This type of ultra precision machining is probably as close as you can come to being perfect.

CNC (computer numerical controlled) technology combined with robotic technology offers every company a better way of doing things. These machines can operate on their own with very little human intervention. Controlled by a computer program, the accuracy of these machines can be matched by no other. The better the program is, the better the machine capabilities are.

In other words, highly skilled programmers can create programs that will allow the closest accuracy that there possibly is. Other things can affect the accuracy of the machines. For instance: the environment. Most facilities have a temperature controlled environment that these machines operate in on a daily basis. Small factors such as this can help with the accuracy of the machine.

The operators of the machine also have a part in the accuracy of the machine. The right tools for the job have to be set up, the material has to be placed properly in the machine and the program has to run right with no flaws. The programs are designed in a code that is for the CNC technology and one little mistake in the program, can make the machine be a little off and the end product that is created will not be to the right specifications.

To be able to gain even more accuracy and precision out of a machine, the operators must "know" their machines. We're not talking about knowing how to load it or how to set it up; the operator must know the technology and the behavior of the machine. Operators, who understand this and know the behavior of their machine, can push the machine beyond the limits that the manufacturers originally developed the machine for. Squeezing every little ounce of precision and accuracy out of a machine can help you to perform a wider range of projects where the results are sure to please anyone.

CNC precision machining can be learned, but the precision can be improved through the knowledge of the operator. There are schools available that can teach you the basics of CNC machining; however, the facts beyond the basics are can be learned through years on the job.
