Description

technical field [0001] The invention relates to a machine tool, specifically a five-axis numerical control machine tool. Background technique [0002] At present, large-scale mold manufacturing technology generally uses three-axis vertical machining centers (CNC machine tools) for processing. When the three-axis vertical machining center processes the mold, the linear speed of the bottom surface is zero, so the finish of the bottom surface is very poor, and the surface processed by the three-axis vertical machining center is a vertical surface, which is often multi-faceted in the processing of complex abrasive tools. For processing, the operator needs to continuously turn over the workpiece, which often leads to changes in the accuracy of the workpiece during the turning process. However, the conventional five-axis machining center on the market uses a cantilever structure, which has weak stability and rigidity, and is prone to vibration patterns during roughing.

Problems solved by technology

When the three-axis vertical machining center processes the mold, the linear speed of the bottom surface is zero, so the finish of the bottom surface is very poor, and the surface processed by the three-axis vertical machining center is a vertical surface, which is often multi-faceted in the processing of complex abrasive tools. For processing, the operator needs to continuously turn over the workpiece, which often leads to changes in the accuracy of the workpiece during the turning process

However, the conventional five-axis machining center on the market uses a cantilever structure, its stability and rigidity are relatively weak, and it is easy to produce vibration lines when roughing. In addition, its tool speed is relatively low, which makes the surface finish relatively weak.

During the cutting process, due to the different processing materials, the quality of the cutting fluid will also be affected, which reduces the cooling effect of the subsequent cutting fluid on the workpiece and the protection of the machine tool; the structure of the conventional five-axis machining center still has certain shortcomings. It is difficult to automatically clean the processed waste materials, and it is impossible to effectively control water and remove chips for waste materials of different materials
