CNC lathe is one of the most widely used CNC machine tools at present. It is mainly used for shaft parts or disk parts of the inner and outer cylindrical surface, any cone Angle of the inner and outer conical surface, complex rotary surface and cylindrical, taper thread machining, and can be cut, drilling, reaming, reaming and boring. In CNC manufacturing, the machine is operated by numerical control, in which the specified software program to control the object. The language behind CNC machining, also known as G code, is used to control various behaviors of the corresponding machine, such as speed, feed rate and coordination. Simply speaking, CNC machining center does not include CNC lathes and CNC milling machine, CNC machining center is also the format of CNC milling machine, but there is a tool library. So CNC is a processing center, and CNC lathe is different from the following points:
Goto LECN to know more.
1. Structural differences.
CNC machining center is at least three axis control, and CNC lathe is two axis control.
2. Processing tool difference.
CNC machining center has a tool library, CNC lathe is used by the tool holder. CNC machining center tool library classification than CNC lathe tool rest classification is more, there are disc type, bamboo hat type, chain type, flying saucer type, with the move type, and so on, most of the tool library capacity is larger than CNC lathe tool rest tool capacity.
3. The processing range is different.
The processing range of CNC machining center is larger than that of CNC lathes. CNC lathes are mainly used to process rotary parts.
4. Programming differences.
The programming of CNC machining centers and CNC lathes is similar in some aspects, but the programming of CNC machining centers is more complex.

CNC machining can pre-program the speed and location of machine tool functions and run them through software in repeated, predictable cycles with little manual manipulation. During CNC machining, 2D or 3D CAD drawings are conceived and then converted into computer code for the CNC system to execute. After entering the program, the operator runs it to make sure there are no errors in the coding. Because of these capabilities, the process has been adopted in all corners of manufacturing, and CNC machining is particularly important in the field of metal and plastics production. The advantages of CNC machining are mainly shown in the following points:
1. CNC can be automatic processing.
CNC machining usually refers to precision machining controlled by computer numbers. Therefore, it can be controlled by the program instructions of CNC machine tools, and the whole machining process is carried out automatically according to the program instructions. Machine tool automation degree is high, greatly reduce the labor intensity of workers.
At present, many CNC machines can be run unattended throughout the machining cycle, freeing up the operator for other tasks. This provides a number of side benefits for CNC users, including reduced operator fatigue, reduced errors due to human error, and consistent and predictable processing times for each job.
2. CNC machining precision is high.
The second major advantage of CNC technology is the consistency and accuracy of the workpiece. Typical accuracy of today's CNC machine tools has reached two to four thousandths of an inch or 0.05 to 0.10 mm, with repeat accuracy close to or better than eight thousandths of an inch or 0.02 mm. This means that once the program is proven, two, ten, or a thousand identical parts can easily be produced with the same precision and consistency. Can realize mass production, product quality is easy to control.
