Five-axis CNC machining is a high-efficiency and high-precision machining method, which uses numerical control technology and five-axis three-dimensional tools, which can greatly improve the processing accuracy and work efficiency of parts. Five-axis CNC machining is widely used in precision machining, such as mold, aviation, aerospace, automotive, medical devices and electronic parts industries.

The advantages of Dongguan five-axis CNC machining are:

1. High-precision machining: five-axis CNC machining adopts numerical control technology, which can be processed according to the predetermined trajectory, which can not only process parts of various shapes and dimensions with high precision, but also ensure high-precision repeatability during processing.

2. High efficiency machining: five-axis CNC machining method does not require manual operation, which can greatly improve production efficiency. More parts can be machined in the same amount of time, thus increasing production efficiency.

3. More kinds of parts can be machined: five-axis CNC machining can process more complex curved parts, with stronger processing capacity. In addition, it can also process a variety of metal and non-metallic materials, such as titanium alloy, aluminum alloy, copper, iron, stainless steel and so on.

4. Reduce the number of parts: Through five-axis CNC machining, many parts can be combined together, thus reducing the number of parts and reducing costs.

5. Environmental protection and safety: five-axis CNC machining process does not require the use of chemicals and other toxic substances, will not have an impact on the environment, but also reduce the operational risk of workers.

When using five-axis CNC machining, it is important to note that:

1. Rational use of tools: for different workpiece materials and processing requirements, different tools need to be selected to obtain better processing results.

2. Keep the equipment clean: It is necessary to keep the equipment clean and in good condition, and maintain it frequently to ensure the normal operation of the equipment.

3. Reasonable setting of processing parameters: For different workpiece materials and processing requirements, it is necessary to set processing parameters reasonably to obtain the best processing effect.

In short, Dongguan five-axis CNC machining is a high-efficiency, high-precision processing method, which has been widely used in many manufacturing industries, and provides an effective means for the manufacturing and production of parts.

1. Five-axis linkage machine tool with double turntable structure

The table set on the bed can be rotated around the X axis, defined as the A axis, the general operating range of the A axis +30° to 120°. There is no rotary table in the middle of the table rotating around the Z axis, defined as the C axis, the C axis can generally be 360° rotation. In this way, through the combination of the A axis and the C axis, in addition to the bottom surface of the workpiece fixed on the workbench, the remaining five faces can be processed by the vertical spindle. The small index value of the A axis and the C axis is generally 0.001°, which can be subdivided into any Angle to process the inclined plane and the inclined hole. A axis and C axis such as X, Y, Z three linear axis to achieve linkage, you can add a complex space surface, of course, this requires the support of numerical control system, servo system and software. The advantage of this setting is that the structure of the spindle is relatively simple, the rigidity of the spindle is very good, and the manufacturing cost is relatively low. However, the general work table can not be designed too large, the load bearing is small, especially when the A-axis rotation is equal to 90°, the workpiece cutting will bring A large cutting moment to the table.

2. Five-axis linkage machine tool with rotating table and swinging head structure

Since the turntable can be A axis, B axis or C axis, the swing head is the same, can be respectively A axis, B axis or C axis, so the turntable plus the swing head structure of the five-axis linkage machine can have a variety of different combinations to adapt to different processing objects. The advantage of this setting is that the spindle machining is very flexible, and the table can also be designed to be very large. The huge fuselage of the passenger plane and the huge engine casing can be machined in this kind of processing. This design has another major advantage: When using a spherical milling cutter to process surfaces, when the center of the tool is perpendicular to the machining surface, because the apex linear speed of the spherical milling cutter is zero, the surface quality of the workpiece cut out by the vertex will be very poor, and the design of the spindle rotation makes the spindle turn an Angle relative to the workpiece, so that the spherical milling cutter avoids the vertex cutting, ensuring a certain linear speed, which can improve the surface processing quality.

This structure is very suitable for mold high-precision surface machining, but it is also difficult to do rotary machining center. In order to achieve high precision of rotation, the rotation shaft is also configured with circular grating scale feedback, and the indexing degree is within a few seconds, of course, the rotation structure of this kind of spindle is more complex, and the manufacturing cost is higher.

3. Five-axis linkage machine tool with double swing head structure

Because of the structure itself, there is generally an electric spindle with a loose broach structure in the middle of the swing head, so the size of the double swing head itself is not easy to make small, generally in 400 to 500mm, plus the need for the range of activity of the double swing head, so the processing range of the five-axis linkage machine tool of the double swing head structure should not be too small, but the larger the better, generally gantry or moving beam gantry, The width of the gantry is better than 2000 to 3000mm.

At present, the more advanced double-swing head type five-axis linkage machine tool swing head structure generally adopts “zero transmission” technology of torque motor “zero transmission” technology in the rotary shaft application is to solve its transmission chain stiffness and accuracy of the ideal technical route. With the development of technology, the manufacturing cost of the twisted motor has been greatly reduced, and the market price has also fallen, and this process will promote the manufacturing technology of the five-axis machine tool to be greatly advanced.
