An aluminum alloy car charger casing manufacturer explains how to add four-axis and five-axis machining using CNC milling machines.

CNC milling machines are typical machinery that integrate advanced technologies, and their development reflects a nation's manufacturing level. They have received great attention both domestically and internationally. Compared with conventional CNC machine tools, CNC milling machines have the following outstanding features:

Compared with conventional CNC machine tools, CNC routers have the following outstanding features:

1. All CNC milling machines are fully enclosed with protective doors. During machining, keeping the protective doors closed can help prevent personal injury accidents.

2. The process is highly concentrated, and machining operations are carried out continuously. CNC milling machines typically feature multiple feed axes (three or more) and even multiple spindles. The number of axes that can be coordinated simultaneously is also very large—such as three-axis linkage, five-axis linkage, and seven-axis linkage—enabling the machine to automatically perform machining on multiple planes and at various angular orientations, thus achieving high-precision machining of complex parts. On a CNC milling machine, a single workpiece setup can complete operations including milling, boring, drilling, reaming, broaching, and tapping, resulting in a highly concentrated machining process.

3. Utilizing multiple tools, the CNC milling machine with an automatic tool changer and tool magazine allows the required tools to be pre-loaded into the magazine before machining. During machining, the tools can be automatically exchanged according to program control.

4. By using multiple workstations, if the CNC machining center is equipped with an automatic exchange table, one workstation can be engaged in machining while another workstation completes the clamping of the workpiece. This significantly reduces auxiliary time and greatly improves machining efficiency.

5. With powerful functionality, CNC milling machines tend toward composite machining, offering integrated turning and grinding capabilities. For example, a rotary table can drive the workpiece to rotate at high speed while the tool performs only the main motion without feed movement, thus achieving machining operations similar to turning. This gives CNC milling machines a broader range of processing applications.

6. The CNC milling machine features high automation, high precision, and high power. It boasts a spindle speed, feed rate, and rapid positioning accuracy that are all exceptionally high. By carefully selecting appropriate cutting parameters, it can fully exploit the cutting performance of the tool, significantly reducing machining time. Moreover, the entire machining process is continuous, with fast auxiliary operations and a high degree of automation, thereby minimizing auxiliary operation time and downtime. As a result, the CNC milling machine exhibits very high production efficiency.

7. High Investment: Due to their high degree of intelligence, complex structure, and powerful functionality, CNC milling machines entail significantly higher initial investment costs as well as ongoing maintenance and upkeep expenses compared to conventional machine tools.

8. Only under the right conditions can CNC machine tools deliver their maximum benefits—meaning that to fully realize their advantages during operation, it’s crucial to leverage the strengths of CNC machine tools. This point is vital for the rational use of CNC routers.
