Machines used in industrial applications must guarantee not only fast and efficient operation, but also high precision and the ability to automate most of the tasks performed. These requirements are met very well by CNC machines, which can be used for various types of machining operations. Let's find out what CNC machines are and what types of machining they are most often used for.
What is specific to CNC machines?
CNC machines are digitally controlled devices. They are equipped with electronic systems that allow the implementation of previously prepared by the operator action programs, reproduced during the machine's operation. This is possible because all of their working components have built-in advanced sensors that provide their position and status and servomechanisms, which can set them in motion in a strictly controlled manner. This allows for their precise positioning, movement and initiation of work movement with established parameters. The entire device is therefore able to accurately reproduce control sequences, and the software used supports the optimization of the entire process, making it faster and more efficient.
Where are CNC machines used?
CNC machines are used for many tasks related to metal, wood and plastic processing. They are used for subtractive processing, i.e. processing in which subsequent fragments are separated from the material in order to obtain the desired shape. An example would be turning, where the material is set in rotation, and a turning tool moving along the appropriate trajectory collects the allowance, or milling, in which a milling cutter is set in rotation, which usually moves in various axes and planes, allowing the proper shape to be obtained. CNC machines can be used for drilling or chiseling. They are also used in plastic processing, including for bending e.g. on press brakes and mechanical cutting using guillotines or cutting dies. They are also extremely useful for thermal cutting e.g. laser or plasma cutting or work using jet processing.
