subject: The Manufacturing Process Of Cnc Turning Machines [print this page] CNC or also known as computer numerical controlled machines are technologically advanced metalworking tools that can help develop sophisticated parts that modern technology requires. The growth in modern technology has made it possible for CNC turning machines to perform as milling machines, laser cutters, lathes, punch presses, press brakes and a host of other industrial tools. These machines use computer logic to perform metalworking and control movements.
Modern design
It is important that the components of the machine have to be rigid and robust so that it can support the moving parts. There are bearings that support the spindle, which is supposed to be the strongest part and the automatic clamping enables the spindle to conveniently clamp as well as unclamp during the complete process. Earlier cast iron used to be the preferred metal, however, today steel and stainless steel are used to minimize cost and to fabricate intricate designs. On the side of the machine, one will find attached magazine of different tools and there is a transfer arm, which replaces one tool with another tool from the magazine.
Manufacturing
CNC turning machines feature advanced technology and can perform all kinds of operations that customers require. The first step of manufacturing is welding the base. The base of the machine can be either casted or welded together and the machine is treated with heat to eliminate welding or casting stresses and therefore ensuring it metal is normalized for machining. The ways are bolted and pinned to the base.
The next step is to bolt the ball screws to the base and ball screws are actually tools that move the spindle. These screws are meant to change the motion of the drive motors from rotary to linear.
The next step is mount the spindle but for that to happen it has to be first machined and then mounted onto the drive motor and finally bolted to the spindle carrier. Each axis contains a separate ball screw and a set of ways. The next step is to get the computer, which is the controller and separate from the rest of the machine. The controller features a climate control enclosure, operating memory, power suppliers, computer boards, electronic circuits etc. There are wires that link the controller to the machine motors. There are also slides that send information regarding the location of the axis to the controller so that the exact position is always known and precision-based results can come out.
Finally, the machine is made to test run for precision and accuracy. Since the machines can have physical differences, these are mathematically corrected through the operating system of the computer. As the CNC turning machine wears due to frequent use over a period of time, the parameters can be recalibrated to ensure precision.
These are the different steps that are followed in the manufacturing process of CNC turning machines and it is important that a stringent procedure is followed because ultimately the aim of a really good CNC turning machine is to offer precision-based results.
