What are the classifications of machining centers?

2023-07-20

The machining center is developed from the basic CNC Milling machine, which integrates all the functions and characteristics of the CNC milling machine, and its structure is the same, and the processing technology is similar. Not only that, the machining center also concentrates the machining functions and processing processes of a variety of machine tools, which can complete multi-process processing of workpiece clamping at one time, such as milling, boring, drilling, tapping and thread tapping and other multi-process processing.

So how are machining centers classified, and how many classification methods are there? Let's talk to GZ to find out.

There are six methods for classifying machining centers, the first is to classify the spindle and the table relative position according to the structure; The second is classified according to the number of control axes; The third axis is classified according to the processing process; The fourth type is classified according to the number of workbenches; The fifth type is classified according to the tool changing method of the tool magazine of the machining center; The sixth type is classified according to the machining accuracy of the machining center.

What are the classifications of machining centers (Figure 1)?

First, according to the relative position of the spindle and the table classification
Machining centers can be divided into four categories according to the relative position of the spindle and the table, namely vertical machining centers, horizontal machining centers, gantry machining centers and composite machining centers.

Second, according to the number of control axes classification
Machining centers can be divided into many categories according to the number of control axes, including three-axis machining centers, four-axis machining these, five-axis machining centers, six-axis machining centers, etc. and other multi-axis machining centers.

Third, according to the processing process classification
Machining centers can be divided into two categories according to the classification of processing operations, namely boring and milling and turning and milling.

4. Classification according to the number of workbenches
Machining centers can be divided into three categories according to the number of workbenches, which are single table machining centers, double table machining centers and multiple worktable machining centers.

5. Classification according to the tool changing method of the tool magazine
Machining centers can be divided into two categories according to the tool changing method of the tool magazine, namely manipulator tool change machining center and non-manipulator tool change machining center.

6. Classification according to processing accuracy
According to the machining accuracy of machining centers, it can be divided into three categories, namely ordinary precision machining centers, high-precision machining centers and precision machining. Among them, the ordinary precision machining center: the resolution is 1μm, the maximum feed speed is 15~25m/min, and the positioning accuracy is about 10μm. High-precision machining center: the resolution is 0.1μm, the maximum feed speed is 15~100m/min, and the positioning accuracy is about 2μm. Between 2~10μm, ±5μm is more, which can be called precision machining center.
