First, the main structure of the two is the same:
1. The main structure of ordinary lathes: the main components of ordinary lathes include spindle box, feed box, slide box, tool holder, tailstock, smooth bar and lead screw.
and bed. 2. CNC lathe.
The main structure: the CNC lathe consists of a CNC device, a bed, a spindle box, a tool holder feed system, a tailstock, and a hydraulic system.
It is composed of cooling system, lubrication system, chip conveyor and other parts.
Second, the role of the two is the same:
1. The function of ordinary lathes: it is often used to process the internal and external rotating surfaces, end faces and various internal and external threads of the workpiece, using the corresponding tools and accessories, and can also be drilling, reaming, tapping and knurling. Ordinary lathes are the most widely used lathes, accounting for about 65% of the total number of lathes, and are called horizontal lathes because their spindles are placed horizontally.
2. The function of CNC lathes: mainly used for the cutting of the inner and outer cylindrical surfaces of shaft parts or disc parts, the inner and outer conical surfaces of arbitrary taper angles, the internal and external curved surfaces of complex rotary and cylindrical and tapered threads, and can be used for grooving, drilling, reaming, reaming and boring.
3. The characteristics of both are the same:
1. The characteristics of ordinary lathes: large low-frequency torque and stable output; high-performance vector control; Fast torque dynamic response, high speed stability accuracy; Deceleration and fast stopping; Strong anti-interference ability.
2. The characteristics of CNC lathe: high processing accuracy and stable processing quality; It can carry out multi-coordinate linkage and process parts with complex shapes; When the processed parts are changed, generally only need to change the CNC program, which can save production preparation time;
The machine tool itself has high precision and rigidity, and can choose a favorable processing amount, and the productivity is high (generally 3 5 times that of ordinary machine tools); The machine tool has a high degree of automation, which can reduce labor intensity; The quality requirements for operators are higher, and the technical requirements for maintenance personnel are higher.

1. CNC lathe:
1. Advantages: The CNC lathe adopts an electric spindle, which cancels the belt, pulley and gear, greatly reduces the moment of inertia of the main drive, improves the dynamic response speed and working accuracy of the spindle, and completely solves the vibration and noise problems of the belt and pulley transmission when the spindle runs at high speed. The electric spindle structure can make the spindle speed reach more than 10000r min.
The linear motor has high driving speed, good acceleration and deceleration characteristics, superior response characteristics and follow-up accuracy. The linear motor is used as servo drive, which eliminates the intermediate transmission link of the ball screw, eliminates the transmission gap (including the reverse clearance), the motion inertia is small, the system rigidity is good, and it can be accurately positioned at high speed, thus greatly improving the servo accuracy.
2. Disadvantages: Compared with ordinary machine tools, the overall performance and efficiency of CNC lathes have been improved, and the application is also relatively wide, therefore, CNC lathes do not have too many shortcomings compared with ordinary machine tools.
2. Ordinary machine tools:
1. Advantages: large low-frequency torque and stable output; high-performance vector control; Fast torque dynamic response, high speed stability accuracy; Deceleration and fast stopping; Strong anti-interference ability.
2. Disadvantages: The operation efficiency and processing efficiency of ordinary machine tools are not as high as those of CNC lathes.

CNC machine tool processing speed is fast, the processing accuracy is unified, only the stool should be adjusted by the debugger, the operator's skill requirements are not high, and the lack of travel points is required in batches; The machining accuracy of ordinary lathes is not uniform, and the operators need to have high skill requirements for dismantling wax liquid, but the requirements for batch size are not high.

1. It can greatly improve the high productivity of Zheng Xiang. After the workpiece clamping is completed, enter the prepared processing program, the machine tool will automatically complete the machining process, and when the processed parts change, generally only need to change the data program, so the processing time is greatly shortened, so that the productivity can be increased several times more than that of the spectrum machine tool.
2. It has high processing accuracy and product quality is very stable. Due to the automatic processing according to the program, the machining accuracy can also be corrected and compensated by the software, so the higher machining accuracy can be obtained, and almost all the high, precise and cutting-edge products in the enterprises are processed and manufactured by CNC machine tools.
3. The high degree of automation reduces the labor intensity and dilutes the difference between physical labor and mental labor to a large extent. The work of CNC machine tool operators has a high scientific and technological content, and the quality of the operators is higher, and the technical requirements for the maintenance personnel are higher.

CNC lathes have many advantages over ordinary lathes, and whether they can completely replace ordinary lathes.
Hello, I am glad to answer for you: CNC lathes have many advantages over ordinary lathes, and can they completely replace ordinary lathesA: Pro-CNC lathes cannot fully replace ordinary lathes at present.
Usually machining large workpieces or long noisy shafts is the strong point of ordinary lathes, and CNC lathes cannot complete such work. CNC lathe is the abbreviation of digital program control lathe, which integrates the characteristics of more than 10,000 key energy lathes with good versatility, precision lathes with high machining accuracy and special lathes with high processing efficiency, and is a CNC machine tool with the largest use and the widest coverage in China. The typical parts processed by CNC lathes are generally shaft sleeve parts and disc parts, which have the characteristics of high machining accuracy, high efficiency and high degree of automation; Thank you for your patience.
If you are satisfied with my service, please give a thumbs up, and once again wish you all the best! Peace and joy!

Answer: The difference between CNC machine tools and ordinary machine tools is:
The machining process of CNC machine tools for parts is carried out in strict accordance with the parameters and actions specified in the processing procedures. It is a high-efficiency automatic or semi-automatic machine tool, suitable for the processing of complex special-shaped parts; High machining accuracy; Stable and reliable processing; High flexibility; High productivity; good working conditions; conducive to management modernization; The investment is large and the cost of use is high; Complex production preparation; It is difficult to maintain compared to ordinary machine tools.
The obvious difference in structure is: CNC machine tools have CNC devices, and there are great differences in the main drive and feed transmission structure. Main drive part:
The original ordinary AC motor drag is changed to DC motor drag, and the corresponding DC speed regulation device is configured. The speed regulation of ordinary AC motors is generally not easy to achieve, and the speed of the spindle needs to be changed through the conversion of the positions of each sliding gear in the spindle box or different speeds. In order to make the spindle can or have a variety of different speeds from low to high, to meet the needs of processing, the number of mechanical gears is generally more, so that the spindle box structure is complex, the volume is huge, in the process of operation, especially at high speed, the vibration and noise are larger, and the machining accuracy of the parts will have a negative impact.
With AC and DC spindle drive or use frequency converter to control the ordinary AC frequency conversion motor can adopt speed closed-loop control, the change of grid voltage and cutting torque has little influence on the motor speed, easy to achieve stepless smooth speed regulation, and the speed regulation range is wide, and the number of mechanical gears required is also less (generally 2 or 4 gears). The reduction of the number of gears leads to the simple structure of the headstock, the reduction of volume, the reduction of vibration and noise during rotation, and the machining accuracy of the parts is higher. Feed transmission part:
The original sliding screw was replaced with a ball screw, and the drive motor was added, the transmission chain was shortened, and the flexibility of the moving parts was improved.
-
The feed of ordinary lathes is to use the feed box, that is, the gear gearbox, and the CNC lathe directly uses a servo motor, and the servo motor has a feedback signal, which can display and control the feed amount and feed speed.
-
The numerical control is controlled by a computer, while the general car does not.
-
The most fundamental difference is the 2 words of CNC. CNC is the abbreviation of digital control, and CNC technology is a method of using digital information to control mechanical movement and machining process. Ordinary machine tools are manually controlled.
In other aspects, CNC machine tools are also different from ordinary machine tools, such as ball screws, inclined beds, standardized indexable tools, fully enclosed structures, frequency conversion motors or servo motor spindles, and linear guides.
Same: The mechanical movement mode is the same, such as CNC lathe and general lathe are both workpiece rotation tool movement.
CNC machine tools and ordinary machine tools follow the same manufacturing principle, such as cutting machine tools follow the principle of metal cutting.
-
Except for automatic tool change, there is no difference between CNC milling and machining centers.
-
Ordinary lathes are driven by gears and ordinary lead screw nuts. By bai, there is a gap between the movement pairs, and the manual operation is not accurate, so the repetition is fine.
The DAO degree is low. When ordinary lathe measurement, it is necessary to measure manually after stopping, and the measurement error is large, and the efficiency is low. It is suitable for small batches, low precision requirements, and zero-live parts.
It has a lower investment than CNC, but it requires higher operational skills from workers, so the wage level is high. Scrap rates and productivity of low-level workers can give you headaches.
CNC lathes rely on stepper motors to drive ball screw transmission, because the ball screw can have interference, transmission without gap, accuracy mainly depends on the machine tool itself and program to ensure the accuracy. It can be measured automatically during the machining process and can automatically compensate for errors caused by tool wear and other reasons. Therefore, the processing is ***, and the accuracy is stable.
It is also possible to use the programming method to turn out parts with complex shapes that are difficult to process with ordinary lathes. It is suitable for parts with high precision, large batch size and complex shape. But small batch production also works well.
Its maintenance cost is higher than that of ordinary lathes.

This is too difficult to say, the key is what you want to know, from the current domestic situation, most manufacturers are manufacturing CNC equipment, the cost of CNC equipment is higher, the failure rate of equipment (as far as domestic machine tools are concerned) is too high, once there is a small failure, the whole machine tool is in a state of paralysis, of course, this is for the operator, the processing capacity of CNC machine tools is strong, for complex, or a single process processing time is longer, you can use CNC machine tools, the accuracy of CNC machine tools The accuracy is higher than that of different machine tools, and the maintenance cost is also high. That's all there is to it.
