Advantages of five-axis CNC machining center

The CNC five-axis machining center has high technology content, high precision, and a wide range of applications. Not only used in the civil industry, but also widely used in aviation, aerospace, military, scientific research, precision equipment, high-precision medical equipment and other industries. Here is a brief introduction to its advantages. The five-axis machining center is particularly suitable for processing molds with complex geometric shapes. Its advantages are as follows:

1. When processing a deep and steep cavity, the additional rotation and swing of the workpiece or spindle head can create the best technological conditions for the processing of the end mill, and avoid collisions between the tool and the tool bar and the cavity wall. It reduces the jitter and the risk of tool damage during tool processing, which is beneficial to improve the surface quality of the mold, the processing efficiency and the durability of the tool.

2. The technology of the five-axis machining center eliminates the need for multiple debugging and chucking required for repositioning the workpiece at a complex angle. This not only saves time, but also greatly reduces the error, and saves the expensive cost of fixtures and fixtures required to install the workpiece in place.

The use of a five-axis linkage machine tool makes it easy to clamp the workpiece. There is no need for special fixtures during processing, which reduces the cost of fixtures, avoids multiple clampings, and improves mold processing accuracy. Using five-axis technology to process molds can reduce the number of fixtures used. In addition, because the five-axis linkage machine tool can save many special tools in processing, the tool cost is reduced. Using five-axis linkage machine tool to process molds can quickly complete mold processing, fast delivery, better guarantee the quality of mold processing, make mold processing easier, and make mold modification easier. In traditional mold processing, a vertical machining center is generally used to complete the milling of the workpiece. With the continuous development of mold manufacturing technology, some of the weaknesses of the vertical machining center itself have become more and more obvious. Modern mold processing generally uses ball-end milling cutters to process. Ball-end milling cutters bring obvious benefits in mold processing. However, if a vertical machining center is used, the linear velocity of the bottom surface is zero, so the bottom surface finish is very poor. , If you use four-axis or five-axis linkage machine tool processing technology to process molds, the above shortcomings can be overcome. In the past ten years, due to the continuous advancement of tools, drives, control and machine tools, high-speed machining and machining, especially high-speed hard milling, have been widely used and promoted in the mold manufacturing industry. Traditional EDM is used in many The occasion has been replaced by high-speed hard milling. Through high-speed hard milling, the comprehensive processing of the mold blanks under one clamping not only greatly improves the processing accuracy and surface quality of the mold, greatly reduces the processing time, but also simplifies the production process, thereby significantly shortening the mold manufacturing Cycle, reducing mold production costs.
