- 1. The CNC lathe can process complex workpieces such as straight cylinders, oblique cylinders, circular arcs and various threads, grooves, worms, etc. It has various compensation functions such as linear interpolation and circular interpolation, and is used in the mass production of complex parts. A good economic effect.
- 2. Numerical control lathes and turning centers are high-precision and high-efficiency automated machine tools. Equipped with multi-station turret or power turret, it has a wide range of processing performance. The CNC machine tool automatically processes the processed parts according to the pre-programmed processing program.
- 3. The machining process route, process parameters, tool motion trajectory, displacement, cutting parameters (spindle rotation, feed, back tooling, etc.) of the part, and auxiliary functions (tool change, spindle forward rotation, reverse rotation, etc.) , Cutting fluid on, off, etc.), in accordance with the instruction code and program format specified by the CNC machine tool to write a processing program list, and then record the content of the program list on the control medium (such as punched paper tape, magnetic tape, magnetic disk, magnetic bubble Memory), and then input into the numerical control device of the numerical control machine tool, so as to direct the machine tool to process the parts.
- 4. This whole process from the analysis of the part drawing to the preparation of the control medium is called the compilation of the numerical control program. The difference between CNC machine tools and ordinary machine tools processing parts is that CNC machine tools automatically process parts according to the program, while ordinary machine tools must be operated by humans. As long as the program that controls the action of the machine tool is changed, the purpose of processing different parts can be achieved. CNC machine tools are especially suitable for processing small batches of parts with complex shapes and high precision requirements.

See lessThe Programmable Logical Controller (PLC) is also a general-purpose automatic control device based on the proud processor. It is also called a Programmable Controller (PC) or Programmable Machine Controller (PC). Programmable Machine Controller, referred to as PMC), is used to complete various logical operations and sequence control of CNC machine tools, such as machine start and stop, workpiece clamping, tool replacement, coolant switch and other auxiliary actions. The PLC also accepts instructions from the machine tool operating panel: on the one hand, it directly controls the actions of the machine tool; on the other hand, it sends related instructions to the CNC for processing control and creation. The PLC in the CNC system has a built-in type and an independent type. The internal I type PLC and CNC are combined and designed, also known as the integrated type, which is a part of the CNC; the independent type PLC is produced by an independent professional factory, also known as the exterior type.
The operation of the CNC machine tool is realized through the man-machine operation panel, which is composed of the CNC panel and the machine tool panel.
The numerical control panel is the operation panel of the numerical control system, which is composed of a display and a manual data input (Manual Data Input, referred to as MDI) keyboard, also known as an MD panel. The lower part of the display is often provided with a menu selection key, which is used to select a menu. In addition to various symbol keys, number keys, and function keys, the keyboard can also be set with user-defined keys. The operator can realize the system management through the keyboard and the display, and input, store, edit and modify the numerical control program and related data. During processing, the screen can dynamically display system status and fault diagnosis reports. In addition, the numerical control program and data can also be imported through the disk or the communication interface box.
The machine tool operation panel is mainly used for the operation of the machine tool in the manual mode, and the operation of the machine tool in the automatic mode. There are various buttons and selection switches on it, which are used for the start and stop of the machine tool and auxiliary equipment, the selection of processing methods, the selection of speed and override, etc.; there are also digital tubes and signal display. The operation panel of medium and small CNC machine tools is often integrated with the CNC panel, but there is a clear boundary between the two. The communication interface of the numerical control system, such as a serial interface, is permanent and located on the machine operation panel.
