Basic principles of CNC lathe
CNC lathe is a machine tool that uses a digital control system to accurately control the movement trajectory of the tool to process hardware accessories. Its working principle is to input the pre-programmed machining program into the CNC system. The CNC system controls the spindle rotation of the lathe to drive the workpiece rotation according to the program instructions, and at the same time controls the tool to move along the axial direction (Z-axis) and radial direction (X-axis) of the workpiece. The rotating workpiece is cut by the tool to process the blank into the required shape.
For example, when processing a simple shaft hardware accessory, the blank bar is first clamped on the spindle chuck of the lathe. The CNC system controls the tool to start cutting from the outer circle of the bar according to the program instructions, gradually reducing the diameter until the machined Shaft that meets design dimensions.
Processing accuracy and control
CNC lathes can achieve high machining accuracy. Its accuracy mainly depends on the control accuracy of the CNC system, the mechanical structure accuracy of the lathe and the accuracy of the cutting tools. Generally speaking, the positioning accuracy of CNC lathes can reach ±0.01mm or even higher, and the repeated positioning accuracy can also meet the processing requirements of high-precision hardware accessories.
Through precise programming, parameters such as the feed speed and cutting depth of the tool can be controlled. For example, when processing precision threaded hardware accessories, the thread pitch and thread profile can be accurately controlled to ensure the accuracy and quality of the thread.
Processing scope and application areas
CNC lathes are mainly used to process rotary hardware accessories, including shafts, discs, sleeves and other parts. Shaft parts such as transmission shafts, motor shafts, etc. in mechanical transmission; disc parts such as flanges, gear blanks, etc.; sleeve parts such as various bushings, sleeves, etc.
In the field of automobile manufacturing, a large number of axles, wheel hubs and other parts are processed by CNC lathes; in the machinery manufacturing industry, screw rods and polished rods of various machine tools are also common products processed by CNC lathes; in the field of hardware tool manufacturing, products such as wrenches, The handle parts of tools such as screwdrivers can also be processed by CNC lathes.
Introduction to precision machining of centering machines
Working principle and structural characteristics of the heart-moving machine
The full name of the CNC lathe is the CNC lathe. Its working principle is that the workpiece rotates driven by the spindle of the machine tool, and the tool feeds along the axial direction of the workpiece. The tool system of the CNC machine can realize multi-axis Linkage. The structural feature of the centering machine is that it has multiple tool stations and can complete multiple processing procedures in one clamping.
For example, when machining a complex slender shaft, the centering machine can perform cylindrical turning at the front tool station, axial drilling at the middle tool station, and thread processing at the rear tool station, and these The process is carried out continuously and there is no need to re-clamp the workpiece.
Precision machining advantages
High precision: CNC machines have significant advantages in precision machining. Due to the use of high-precision spindle system, guide rail system and advanced CNC technology, the processing accuracy of the centering machine can reach ±0.002mm or higher, which can meet the processing of hardware accessories with extremely high requirements for dimensional accuracy and shape accuracy, such as aerospace Some small shaft parts in the field, precision needle tubes in medical equipment, etc.
Efficient processing of complex parts: The centering machine can complete a variety of complex processing procedures in one clamping, greatly improving processing efficiency. For some slender shaft parts with multiple features, traditional processing methods may require multiple conversions between different machine tools, while the centering machine can complete all processes in one machine tool, reducing the number of clamping times. error, and also shortens the processing cycle.
Good surface quality: During the processing of the centrifugal machine, because the movement mode and cutting parameters of the tool can be accurately controlled, good surface quality can be obtained. The surface roughness of the hardware accessories processed by it can reach below Ra0.8μm. For some parts that require high surface finish, such as shaft parts of precision instruments, centering machining is an ideal choice.

Precision machining of centering machines is widely used in the field of precision hardware accessories manufacturing. In the electronics industry, it is used to process various precision small shafts, pins, etc.; in the medical device industry, it is used to manufacture precision components such as surgical instruments and implantable medical devices; in the field of watch manufacturing, it is used to process watch machines. High-precision parts such as mandrels and pointer shafts.
The importance of precision machining of centering machines lies in its ability to meet the processing needs of modern manufacturing industries for high-precision, high-efficiency, and high-complexity hardware accessories. With the continuous development of science and technology, many industries have increasingly higher requirements for precision hardware accessories. The emergence and development of precision machining technology of centering machines has provided reliable processing solutions for these industries.
