The difference between CNC lathes and ordinary lathes

At present, there are many domestic CNC lathe manufacturers, but there are not many machine tool manufacturers specializing in heavy-duty CNC lathes, among which Zhongtuo machine tool is very good. Dezhou Zhongtuo machine tool focuses on large-scale CNC lathes and roll lathes, has mature machine tool production experience, core team (design, technology, assembly, quality control, service) personnel, have more than ten years of work experience, has successfully provided customers with the largest rotary diameter of 3150mm, the maximum processing length of 15m, bearing capacity of 60 tons of all kinds of large CNC lathes, roll lathes, turning and boring compound machine tools, turning and milling compound machine tools. The high-end CNC machine tools developed by the company have the advantages of large-scale, precise, high-speed, high-efficiency and intelligent, and provide a large number of high-quality CNC machines for aerospace, automobile, mold, mining, construction machinery, wind power and nuclear power, large-scale water conservancy and military industries

There are the following differences:

First, the difference between the mechanical part.

Ordinary lathes use gears to change speed, and you need to pull the shift handle to change speed, and CNC lathes generally use CNC programs to change speeds.

Ordinary lathes use trapezoidal thread screw rod to process threads, smooth rods for cutting, CNC lathes are used ball screws.

The tool holder of the ordinary lathe is generally on the operator's side, most of the tool holder of the CNC lathe is opposite the operator, and the tool holder of the economic CNC lathe is on the operator's side.

The guide rails of ordinary lathes are all hard rails, and the guide rails of CNC lathes have hard rails and linear rails.

Ordinary lathes have large carriage handles, medium carriage handles, and small carriage handles, while CNC lathes do not have these handles, and there is no small carriage.

Second, the difference between the electrical part.

The spindle motor of ordinary lathes is generally an ordinary motor, and the spindle motor of CNC lathes is often a frequency conversion motor or servo motor.

The spindle, feed, and cooling pump of ordinary lathes are all manually controlled, and CNC lathes are controlled by CNC programs. (Manual is also possible).

Ordinary lathes do not have numerical control devices, and CNC lathes have numerical control devices.

The machining principle of CNC lathes is the same as that of ordinary lathes. The difference is that its feed, pass, speed and other parameters are driven by stepper motors or servo motors under program control (ordinary lathes are manual), so it can process specific surfaces and curves, and is also suitable for using specific programs to control the consistency of batch products.

CNC lathes are computer-controlled lathes, which can automatically process products according to programming. High yield efficiency for mass production.

Ordinary lathes are operated manually step by step, which can be seen to be clumsy. But it is also inseparable from it.

Ordinary lathes plus CNC systems and ball screws are CNC lathes, and CNC lathes plus tool magazine and spindle angle control are turning machining centers.

CNC lathes are aimed at high-volume production, while ordinary lathes are aimed at single-piece production.

Foxconn Weixin introduced the characteristics of CNC lathes and ordinary lathes.

CNC lathes and turning centers are high-precision and high-efficiency automatic machine tools. Equipped with a multi-station turret or a driven turret, the machine tool has a wide range of processing process performance, can process linear cylindrical, oblique cylindrical, circular arc and a variety of threads, grooves, worms and other complex workpieces, with linear interpolation, arc interpolation various compensation functions, and in the mass production of complex parts play a good economic effect.

CNC milling machine is an automatic processing equipment developed on the basis of general milling machine, the processing technology of the two is basically the same, and the structure is somewhat similar. CNC milling machines are divided into two categories: without tool magazine and with tool magazine. Among them, the CNC milling machine with a tool magazine is also called a machining center.

In addition to the characteristics of ordinary milling machine processing, CNC milling processing also has the following characteristics:

Machining center (6 photos).

1. The adaptability and flexibility of parts processing are strong, and the parts with particularly complex contours and shapes or difficult to control the size can be processed, such as mold parts, shell parts, etc.;

2. It can process parts that cannot be processed by ordinary machine tools or are difficult to process, such as complex curve parts described by mathematical models and three-dimensional space surface parts;

3. It can process parts that need to be processed in multiple processes after a clamping and positioning;

4. The processing accuracy is high, the processing quality is stable and reliable, the pulse equivalent of the CNC device is generally high-precision, and the high-precision CNC system can reach, in addition, the CNC machining also avoids the operator's operation error;

5. The high degree of production automation can reduce the labor intensity of the operator.

If you choose to get a job, it is recommended to study a machining center, which has a high salary. But having said that, whether it is a car or a mill, if it is done well, the treatment is good. Of course, please don't go to those companies that only need to clamp and start standard parts and batch parts, and try to go to some companies that do non-standard products, so that you can really exercise your skills!

The difference is large, and the main manifestations are:

1. The CNC lathe rotates the workpiece and the tool moves. CNC milling machine is the tool rotation and the workpiece moving.

2. CNC lathes mainly process rotating parts, and CNC milling machines are suitable for processing other types of parts.

3. The numerical control systems of the two are different.

4. The structure of the machine tool is different.

5. The operation methods of the two are different.

6. The spindle speed of the CNC lathe will not be very high, and the maximum spindle speed of the CNC milling machine is very high.

CNC lathe, and CNC milling machine are machine tools, but there is a big difference between the two CNC lathe is a kind of turning equipment, is the workpiece follows the spindle rotation, tool processing of a kind of machine tool CNC milling machine is the workpiece is installed on the work surface, the spindle rotation drives the tool to process the workpiece, the lathe is generally two-axis processing, the milling machine is generally three-axis processing, learning: the lathe is easy to learn compared to the milling machine.

Finally, remind you that the machining industry is a technical job, you need to persevere, ten years like staying in a relative environment, ten years later you will find that machining is a real blue-collar job.
