棱柱形零件的車銑加工

加工中心執行多工序 (轉動, 銑削, 鑽孔, 無聊的, 竊聽, ETC。) 透過自動換刀和工作台分度對棱柱形零件進行多面複合加工. 實務證明複合加工中心確實有利於解決交貨期長的缺點, 資源利用率低, 中小型機械製造業在製品較多，資金周轉緩慢. 車銑複合加工因而在工業生產上得到越來越普遍的應用.

棱柱形零件的CNC加工

在那之後, the spindle head of the CNC machining center was automatically rotated 90 degrees to convert the vertical and horizontal modes. The CNC machining center can not only process the 4 sides of the box part, but also process the 5th surface-the top surface. 因此, the so-called 5-face machining center has been introduced, which can also be regarded as an improvement in the composite processing function of the machining center. 最近幾年, with the price reduction and popularization of 5-axis linkage CNC equipment and programming software, 5-axis linkage (or multi-sided) machining centers have become a new hot spot in the recent international machine tool exhibition. Recently, a machining center was introduced, which can mill and drill the 6 faces of the bar in one clamping. The CNC machining center for bar materials is a new development of multi-faceted compound machining capabilities.

In terms of composite processing of prismatic parts with different processing methods, the current eye-catching trend is the combination of milling processing and laser processing or ultrasonic processing. The German DMG company added a laser processing head to the high-speed milling machine a few years ago, and launched the DMU60L (the current model is DML60HSC) for milling and laser combined processing. The machine is equipped with a Q-switched YAG laser with a power of 100W, a beam diameter of 0.1mm, and a processing efficiency of 20mm3/min. After the workpiece (mainly the mold) is clamped on this machine tool, the high-speed milling head is used to complete most of the work, and then the laser is used for finishing in layer cutting. Remove the milling traces of the profile and process the fine parts, including engraving patterns and patterns.

Hard and brittle materials such as glass, ceramics, 硬質合金, ETC。, are difficult to process with traditional techniques. 然而, if high-frequency vibration motion is added to the traditional milling, 鑽孔, and grinding processes, 那是, ultrasonic technology is combined with cutting processing technology, the processing efficiency will be significantly improved. The DMS series ultrasonic processing machine tool of DMG company in Germany uses the converter on the spindle to convert the electrical high frequency signal of the ultrasonic generator into 20KHz mechanical vibration motion (longitudinal motion). Then the vibration amplitude is amplified and controlled by the voltage regulator, and then all the vibration is transmitted to the milling cutter, drill or grinding wheel made of diamond particles through the patented Sauer conical tool holder. 機械加工過程中, the tool is continuously tapped on the surface of the workpiece 20,000 times per second to separate the surface material of the part in the form of tiny particles. Not only its processing efficiency is increased by 5 times compared with the traditional method, but also the surface roughness can reach Ra<0.2μm. DMS series ultrasonic processing machine tools have two types: 3-axis linkage control and 5-axis linkage control. The spindle speed is 20～6000r/min, and the tool magazine and automatic tool changer are also optional. So it becomes a machine tool that not only has the function of ultrasonic processing, but also can perform multi-process compound processing such as drilling, 銑削, 和研磨.
