High-speed cutting increases the processing speed High-speed cutting performs high-speed cutting of automobile molds at a cutting speed about 10 times higher than that of conventional cutting. Since the excitation frequency of the high-speed machine tool spindle far exceeds the natural frequency range of the "machine tool-tool-workpiece" system, the machining process of automobile molds is smooth and shock-free.
The high-speed machining technology of automobile molds has the following advantages:

High-speed machining has high production efficiency. Machining the mold with a high-speed machining center or a high-speed milling machine can complete the roughing and finishing of the profile and the machining of other parts of the automobile mold in one clamping of the workpiece, which is the so-called "One Pass Machining" technology.
The application of high-speed cutting technology has greatly improved the development speed of automobile molds. High-speed machining can obtain high-quality machined surfaces. Due to the extremely small step distance and depth of cut, high-speed cutting can achieve high surface quality, and it can also save the process of finishing the fitter. Simplified machining procedures Conventional milling can only be carried out before quenching, and the deformation caused by quenching must be manually trimmed or formed by electrical machining. This can now be done by high-speed machining without the surface hardening caused by electrical machining. In addition, due to the reduced cutting amount, high-speed machining can use smaller diameter tools to process smaller corner radii and mold details, saving part of the machining or manual trimming process, thereby shortening the production cycle.
High-speed cutting makes the repair process of automobile molds more convenient. Automobile molds often need to be trimmed many times during use to prolong their service life. If high-speed cutting is used, the work can be completed faster and the processing results of milling instead of grinding can be obtained. , and the original NC program can be used without reprogramming, and can be accurate. Machining can process hard automobile molds with complex shapes.
It can be seen from the high-speed cutting mechanism that the cutting force is greatly reduced during high-speed cutting, and the cutting process becomes easier. High-speed cutting has great advantages in cutting high-strength and high-hardness materials, and can process complex profiles and high hardness. car mold.
