There are 4 main types.
1, the traditional specialized CNC system, this type of CNC system hardware developed by the CNC system manufacturers themselves, with a strong specialization, after a long time of use, quality and performance stability and reliability, is still occupying most of the market in the manufacturing industry.
2, PC embedded in the NC structure of the open CNC system, this type of CNC system and the traditional specialized CNC system, compared with the structure of some openness, very powerful, but the system hardware and software structure is very complex, the system price is also very expensive.
3, NC embedded in the PC structure of the open CNC system, the hardware part of this CNC system by the open architecture of the motion control card and PC organizations. Motion control card is usually used as a high-speed DSP CPU, has a strong motion control and PLC control capabilities.
4, all-software type of open CNC system, this is a new type of open architecture of the CNC system, all the CNC functions, including interpolation, position control, etc. are all realized by the computer software.

Precautions:
Before turning on the electricity, we should check the appearance, electrical piping and some of its parts. The appearance of the electrical pipeline and some of its external auxiliary equipment, whether there are abnormalities. In particular, external auxiliary equipment with hydraulic system pumping station, to observe whether the amount of hydraulic fluid is sufficient, with pneumatic system, to carry out regular air compressor, gas storage pressure vessel drainage, to prevent the accumulation of excessive moisture, driven by airflow into the interior of the machine tool, causing rust and corrosion of the parts and components, or even damage.
Touch the temperature of the machine tool, the machine tool in operation, there is a certain temperature increase is normal, because there is a friction in the process of operation, thus generating heat, in general, when the machine tool operation reaches a certain period of time, it will reach a thermal balance, that is, the temperature is basically constant, roughly in the 50-60 degrees, if you take a hand and put it on the, do not dare to stay, indicating that this time the temperature is too high, it should be Check whether the lubrication is sufficient.
