The three-line machining center is a typical mechanical three-line machining center equipment integrating high and new technology. Its development represents the level of a country's manufacturing industry and is highly valued at home and abroad.

Compared with ordinary CNC machine tools, it has the following outstanding features:

1. Fully enclosed protection

All machining centers have protective doors. When processing, closing the protective doors can effectively prevent personal injury accidents.

2. The process is centralized, and the processing is carried out continuously

The machining center usually has multiple feed axes (more than three axes), even multiple spindles, and the number of linkage axes is also large, such as three-axis linkage, five-axis linkage, seven-axis linkage, etc., so it can automatically complete multiple plane and The machining of multiple angular positions realizes the high-precision machining of complex three-line machining center parts. Milling, boring, drilling, expanding, reaming, tapping, etc. can be completed in one clamping on the machining center, and the processes are highly concentrated.

3. Use multiple tools, automatic tool exchange

The machining center is equipped with a tool magazine and an automatic tool changer. The required tools are loaded into the tool magazine before processing, and the tools can be automatically replaced by program control during processing.

4. Use multiple workbenches, and workbenches are automatically exchanged

If the machining center is equipped with an automatic exchange of worktables, one worktable can be processed while the other worktable completes the clamping of the workpiece, thereby greatly shortening the auxiliary time and improving the processing efficiency.

5. Powerful functions, tend to compound processing

The machining center can combine turning functions, grinding functions, etc. For example, the circular table can drive the workpiece to rotate at a high speed, and the tool only performs the main motion without feeding, completing similar turning processing, which enables the machining center to have a wider processing range.

6. High automation, high precision and high efficiency

The spindle speed, feed rate and rapid positioning accuracy of the machining center are high. Through the reasonable selection of cutting parameters, the cutting performance of the tool can be fully utilized, and the cutting time can be reduced. The entire machining process is continuous, various auxiliary actions are fast, and the degree of automation is high. Auxiliary motion times and downtimes are reduced, so the machining center is highly productive.

7. High investment

Due to the high degree of intelligence, complex structure and powerful functions of the machining center, the one-time investment and daily maintenance costs of the machining center are much higher than those of ordinary machine tools.

8. Only under appropriate conditions can good benefits be exerted

That is to say, in the process of use, the advantages of the machining center must be exerted in order to fully reflect the benefits, which is very important for the rational use of the machining center.
