Learning CNC lathe needs some basic knowledge, usually need to learn about 2-3 years to be able to master.
A, CNC lathe introduction
CNC lathe is one of the more widely used CNC machine tools. It is mainly used for shaft parts or disk parts of the internal and external cylindrical surface, any cone angle of the internal and external conical surface, complex rotary internal and external surfaces and cylindrical, tapered threads and other cutting, and can be grooved, drilling, reaming, reaming and boring.
The CNC machine is in accordance with the pre-programmed machining program, automatic processing of the parts to be processed.
We put the parts of the machining process route, process parameters, tool trajectory, displacement, cutting parameters and auxiliary functions, according to the CNC machine tools specified instruction code and program format written into a processing program list, and then the contents of this program list is recorded in the control media, and then input to the CNC machine tools in the CNC device, so as to command the machine tool to process the parts.
In July 2023, the 25th Institute of the Second Academy of Aerospace Science and Industry successfully developed a high-precision optical automation centering CNC lathe integrating optical detection, fine-tuning and machining, and passed the verification of the engineering pilot application, with the technical level reaching a leading position in China.
Two, CNC lathe machine components
1, host
He is the main body of the CNC machine tool, including the machine body, column, spindle, feed mechanism and other mechanical components. He is used to complete a variety of mechanical components of cutting processing.
2, CNC device
is the core of CNC machine tools, including hardware (printed circuit boards, CRT monitors, key boxes, paper tape readers, etc.) and the corresponding software, used to enter the digital parts program, and complete the storage of the input information, the transformation of the data, interpolation algorithms, as well as the realization of various control functions.
3, drive device
He is the actuator of the CNC machine tool drive components, including the spindle drive unit, feed unit, spindle motor and feed motor. He is under the control of the CNC device through the electrical or electro-hydraulic servo system to realize the spindle and feed drive. When several feed linkage, it can complete the positioning, straight line, plane curve and space curve processing.
4, auxiliary devices
This refers to some of the necessary supporting components of the CNC machine tool to ensure that the operation of the CNC machine tool, such as cooling, chip removal, lubrication, lighting, monitoring and so on. It includes hydraulic and pneumatic devices, chip removal devices, exchange table, CNC rotary table and CNC indexing head, but also includes the tool and monitoring detection devices.
