Have Proper Consideration Before Opting For The CNC Machining Center For Sale

Now widespread in industrial processing, for the realization of objects with extreme precision from very different materials, thanks to the instructions given by a computer, CNC machines have now evolved into Cyber-Physical Machine Tools.

The CNC machines (Computerized Numerical Control), or computerized numerical control machines, are tools whose movements are controlled by an integrated digital device in the machine. The great advantage lies in the fact that the movements and functions are predetermined. That is, they are preset via specific software. This feature makes CNC machines ideal for high-precision machining that requires long times. Before you opt for the CNC machining center for sale (ขาย เครื่อง cnc machining center, which is a term in Thai) you need to know the following:

The evolution of CNC machines has led to new systems made according to the dictates of Industry 4.0. These systems are characterized by being innovative, connected, and widely accessible with greater adaptability and autonomy. However, CNC machines should not be confused with robots, made using more advanced technologies, and able to adapt and react to changes in the environment and sudden obstacles. 

A Brief History of CNC Machines

The first numerically controlled machines were developed at the Massachusetts Institute of Technology (MIT)in the second half of the 1940s, following some research activities related to constructing the components of a new airplane designed by Lockheed. The first step was the adaptation of the conventional machines of the time to numerical control. The first NC machines were conceived for fixed or manual processing cycles. The added control systems were used only for relative positioning between the tool and the component being machined. Although machining times were consistently contained, the operator was still left with the choice of device, speeds, and machining paths. The following solution consisted of the continuous control of the tools according to coordinated and simultaneous movements in the three Cartesian axes (controlled axes). This is important for you to know before you go to the CNC machining center for sale.

The Step More

A further step in their progress was that of obtaining the subtraction of the material at the same time as controlling the relative movements of the tool component being machined. These machines also featured solutions for storing settings on magnetic tape or punch card systems, which were difficult to edit and had limited storage capacity.

Last Words

In 1980 the G – Code language became the EIA RS-274-D standard; this standard was almost entirely transcribed in the ISO 6983 standard. This language is currently used even in the most advanced CNC machines, with few differences and updates by the control systems manufacturers. The advent of a language led to the introduction of CNC machine tools, thanks also to advances in computers in the 1970s.
