High speed machining is the development trend of automobile mould manufacturing.High speed machining technology is an advanced manufacturing technology in the 21st century, which has strong vitality and broad application prospects. High speed machining technology can solve a series of problems which are perplexed in the conventional machining of automobile die. In recent years, high-speed machining technology has been widely used in most mold companies in the United States, Germany, Japan and other industrial developed countries. About 85% of the die EDM process has been replaced by high-speed machining. High speed machining technology, which integrates high efficiency, high quality and low consumption, has become the mainstream of international mold manufacturing technology.
Through the practice and application of high-speed cutting technology in the automobile mold manufacturing industry at home and abroad, high-speed cutting technology has the following advantages:High speed machining improves machining speedHigh speed machining is used to cut automobile die at a speed about 10 times higher than that of conventional cutting. Because the exciting frequency of high-speed machine tool spindle is far beyond the natural frequency range of "machine tool workpiece" system, the machining process of automobile die is stable and impact free.High efficiency of high speed
machining.By using the high-speed machining center or high-speed milling machine to process the mold, the rough and finish machining of the mold surface and the machining of other parts of the automobile mold can be completed in the one-time clamping of the workpiece, that is, the so-called "one pass machining". The application of high-speed cutting technology has greatly improved the development speed of automobile die.
High quality machining surface can be obtained by high speed machiningBecause of the small step distance and cutting depth, high-speed machining can obtain high surface quality, and even eliminate the process of fitter polishing.Simplify the process:Conventional milling can only be carried out before quenching, and the deformation caused by quenching must be finished by hand or finally formed by EDM. Now it can be finished by high-speed machining, and there is no case hardening caused by EDM. In addition, due to the reduction of the cutting amount, the tool with smaller diameter can be used to process the smaller fillet radius and mold details in high-speed machining, which saves some machining or manual finishing processes, thus shortening the production cycle.High speed machining makes the repair process of automobile die more convenientIn the process of using the automobile die, it often needs to be repaired many times to extend its service life. If high-speed cutting is adopted, the work can be completed faster, and the machining effect of milling instead of grinding can be achieved. Moreover, the original NC program can be used without reprogramming, and the accuracy can be achieved.
