Five-axis CNC machining is a mode of CNC machine tool processing. The machining centers we usually use now are generally three-axis three-linked machining centers. Three-axis refers to the X-axis, Y-axis and Z-axis of the machining center, and of course there are Four-axis machining center, four-axis machining center refers to the X-axis, Y-axis, Z-axis and A-axis, where the A-axis refers to the axis that rotates around the X-axis. The five-axis machining center refers to the B-axis in addition to the X-axis, Y-axis, and Z-axis. The B-axis refers to a rotation axis around the Y-axis. This technology has been widely used in high-precision instrument manufacturing fields such as ships, aerospace, automobiles, light industry, and medical treatment.

1. Reduce processing time

Three-axis machining centers and vertical machining centers are commonly used in traditional mold processing to complete the milling of workpieces. With the development of mold manufacturing and processing technology, the ball-end milling cutter commonly used in traditional mold processing has obvious benefits, but if it is used For vertical machining centers, the bottom surface speed is zero and the finish is poor, so the weaknesses of traditional mold processing gradually appear. The five-axis machining can process different sides of the workpiece without changing the position of the workpiece on the machine tool, which can greatly improve the processing efficiency of prismatic parts.

In five-axis machining, flat-bottomed end mills are used to maintain a vertical state of the complex mold processing surface, which can greatly reduce the processing time. The principle of the five-axis machining center is also suitable for side milling with angled surfaces, which can eliminate rib-like lines caused by the processing of the ball end mill, making the surface quality of the mold more ideal, and reducing the need to clean the surface of the mold. The workload of manual milling and manual work.

2. High production efficiency

The five-axis machining center can effectively reduce the machining time and auxiliary time of the parts. The five-axis linkage machining center has a large range of spindle speed and feed, allowing the machine tool to perform powerful cutting with a large amount of cutting. The five-axis linkage machining center is currently entering In the era of high-speed machining, the rapid movement and positioning of moving parts of the five-axis machining center and high-speed cutting processing have reduced the turnaround time between semi-finished products and improved production efficiency.

3. Improve processing accuracy

Through the five-axis machining technology, the problem that the workpiece needs to be repositioned at a complex angle and needs to be debugged multiple times is solved, which not only shortens the time, but also greatly reduces the error generated. The tooling fixture required when installing the workpiece The large amount of cost has also been saved, and the machine tool has also achieved the processing of complex parts, such as the drilling, taper processing, and cavity recesses required for complex surfaces, which are not possible with traditional methods.
