Main features of CNC machining center
According to statistical data, the CNC machining center is one of the most widely used CNC machine tools in the current industrial production industry. This is a full-featured CNC machine tool that integrates high-tech functions such as milling and boring. A variety of processing technology, its development represents the level of a country’s manufacturing industry. Its main features are:
First, fully enclosed protection
The CNC machining center has a protective door. When processing, close the protective door, which can effectively prevent personal injury accidents.
Second, the use of multiple tools, automatic tool exchange
The CNC machining center is equipped with a tool magazine and an automatic tool changer. Before processing, the required tools are first loaded into the tool magazine. During processing, the tools can be automatically changed by program control.
Third, the process is concentrated and the processing is carried out continuously
CNC machining centers usually have multiple feed axes (more than three axes), and even multiple spindles, the number of linked axes is also large, such as three-axis linkage, five-axis linkage, seven-axis linkage, etc., so it can automatically complete multiple planes And the processing of multiple angle positions to achieve high-precision processing of complex parts. One-time clamping in the machining center can complete milling, boring, drilling, expanding, reaming, tapping and other processing, the process is highly concentrated.
Fourth, high automation, high precision and high efficiency
The spindle speed, feed speed and fast positioning accuracy are high, and the reasonable selection of cutting parameters can give full play to the cutting performance of the tool and reduce the cutting time. The entire machining process is continuous, various auxiliary actions are fast, and the degree of automation is high. Auxiliary action time and downtime, therefore, the production efficiency of the machining center is very high.
Fifth, use multiple workbenches, automatic exchange of workbenches
If there is an automatic exchange worktable on the CNC machining center, one worktable can be processed while another worktable completes the clamping of the workpiece, thereby greatly shortening the auxiliary time and improving the processing efficiency.
Sixth, powerful functions, tend to compound processing
It can have compound turning function and grinding function. For example, the round table can drive the workpiece to rotate at high speed, and the tool only performs the main motion without feeding. It completes similar turning processing, which makes the machining center have a wider processing range.
Seventh, the best benefits can be achieved only under appropriate conditions
That is, it is necessary to give full play to the strengths of the machining center in the process of use, so as to fully realize the benefits. This is very important for the reasonable use of the machining center.
Eighth, powerful, high investment
Due to the high degree of intelligence, complex structure and powerful functions of the CNC machining center, the investment and daily maintenance costs of the machining center are much higher than those of ordinary machine tools.
