What is the difference between CNC lathe and machining center?

The machining center has more Y-axes than CNC lathes, and CNC lathes only have X, Z axes.

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.

There are various forms of CNC milling machines, and although different types of CNC milling machines are different in composition, they have many similarities. The following takes the XK5040A CNC vertical lifting table milling machine as an example to introduce its composition. The saw 040A CNC vertical lifting table milling machine is equipped with four 3mA numerical control systems, which are fully digital AC servo driven.

The machine tool is composed of 6 main parts, namely the bed part, the milling head part, the workbench part, the transverse feed part, the lifting table part, the cooling and lubrication part. The internal layout of the bed is reasonable, with good rigidity, the base is provided with 4 adjusting bolts, which is convenient for the machine tool to be adjusted horizontally, and the cutting fluid reservoir is located inside the machine base.

A machining center is a CNC machine tool that has an automatic exchange device and can continuously perform a variety of process processing. It was developed from CNC milling machines.

The biggest difference with the CNC milling machine is that the machining center has the ability to automatically exchange processing tools, by installing tools for different purposes on the tool magazine, the ability to automatically exchange processing tools in a clamping, and by installing different tools on the tool magazine, the processing tools on the spindle can be changed through the automatic tool change device in a clamping magazine, so as to realize a variety of processing functions.

In addition, CNC milling machines only have three axes, while machining centers can be four-axis or five-axis linkage, which is more widely used than CNC milling machines.

The differences between machining centers and CNC lathes are as follows:

1. The movement mode is different: the machining center is the spindle to drive the tool to rotate, and the CNC lathe is the spindle to drive the workpiece to rotate;

2. Different processing objects: CNC lathes are mainly for rotary body processing, and the machining center can process multiple surfaces;

3. The number of tools is different: there are fewer tools in CNC lathes and more tools in machining centers.

CNC machine tools have the following characteristics:

1. Strong adaptability to the processing object, adapt to the characteristics of single piece production of molds and other products, and provide a suitable processing method for the manufacture of molds;

2. High processing accuracy and stable processing quality;

3. It can carry out multi-coordinate linkage and process parts with complex shapes;

4. When the processed parts are changed, the CNC program only needs to be changed, which can save the production preparation time;

5. The machine tool itself has high precision and rigidity, and can choose a favorable processing amount and high productivity (generally 3-5 times that of ordinary machine tools);

6. The machine tool has a high degree of automation, which can reduce labor intensity;

7. It is conducive to the modernization of production management. CNC machine tools use digital information and standard processing and transmission of information, and use computer control methods, which lays the foundation for the integration of computer-aided design, manufacturing and management;

8. The dust vertical has higher requirements for the quality of operators and higher technical requirements for maintenance personnel;

9. High reliability. <>
