German technology is characterized by continuous innovation and research and development. Even in the financial crisis, it still attaches great importance to the development of new technologies. They are conscious of taking a certain percentage of sales from sales to invest in innovation and research and development to seek sustainable and healthy development of the company. This is worth our effort. Chinese business learning. This article will show the innovation achievements of the German machine tool industry with several latest technological innovation examples for readers. Hermle (Hammer): 5-axis milling technology replaces the traditional tooth surface machining process The C-series high-performance machining center launched by the famous German machine tool manufacturer Hermle (Hammer), with its excellent 5-axis full milling capability in gear processing With unique application advantages, the company claims that the 5-axis milling technology it has developed can already replace traditional tooth flank machining. According to reports, this series is suitable for single piece, prototype piece, sample piece, substitute piece and serial production of gear cutting parts with a diameter of more than 500 mm, and can process almost all tooth surface shapes. With larger 5-axis high-performance machining centers such as the C 40 or C 50 in the series, the machining dimensions can be up to 1,200 mm in diameter. While pre-milling, gear flank milling and hobbing or flank joining, hardening, grinding etc. still dominate today, the Hermle C 40 and C 50 universal 5-axis machining centres offer the advantages It is based on the innovative 5-axis gear cutting and the special software provided by the partner HPG High Precision Gear Company. HPG is the only company in the world that uses the above mathematical method for tooth profile modeling, which can obtain higher resolution than ordinary CAD data models. In this way, the NC program has been adjusted to optimize rough and fine grinding. Therefore, the production of milling gear cutting parts only needs to be completed by auxiliary process steps such as rough grinding, quenching, fine grinding, and final fine machining. All machining processes except quenching are completed in the machining center. For rough/finish grinding, the cost of the tool used is low, there is no need for expensive specialized milling cutters, hobs, cutters or grinding wheels, and of course, no additional NC programs are required. Wendt: Perfectly providing a complete set of modern material grinding solutions. Wendt face grinder WBM 205 CDR, based on the grinding machine WBM eco, newly developed a self-rotating workpiece support surface, which is especially suitable for grinding superhard materials. Double end face. The two driving workpiece support surfaces on each vibrating table of the grinding machine can rotate under the grinding wheel. The advantages of this working method are that the flatness and parallelism of the blade are extremely high, up to 2 μm or less, and the surface texture of the blade is very fine. , the surface roughness is below 0.1 μm, which is in the polishing range. The continuous in-line dressing system ROTODRESS keeps the fine-grained grinding wheel uniform and sharp at all times, thus achieving the highest dimensional and topographical accuracy. The WAC 735 CENTRO 5-axis CNC grinding center WAC 735 CENTRO has a 360°x360° axis motion principle and an innovative flexible fixture design, which realizes one-time clamping, and can fully process the periphery, groove, cutting groove and negative chamfering of the insert. Taking the processing of modern new materials as the theme, Wante uses the combination grinding wheel of dish-shaped coarse particles and bowl-shaped fine particles for the first time to efficiently grind the periphery of PCD blades. The newly developed C-type fixture AXR, with axial and radial supports, greatly enhances the rigidity when grinding PCD. Dressing is also required due to the disc-shaped grinding wheel, so a high-precision dressing shaft was added to the grinder. The WANT 4-axis CNC peripheral grinding center WAC 715 QUATTRO is ideal for the efficient grinding of cutting tools, such as indexable inserts, with the shortest grinding and auxiliary times, and the highest availability. As an upgraded version of the worldwide popular grinding machine WAC 715 SCALAR, the WAC 715 QUATTRO has the same basic structure as the 5-axis grinding center WAC 715 CENTRO. The main innovation of this grinder is the use of hydrostatic bearings. By improving rigidity and shock resistance, even superhard materials can be machined at high feed rates, while achieving no chipping and the highest cutting edge quality. In addition, the expansion of the stroke of the feed axis (X axis) greatly increases the processing range of the grinder. The central prism is integrated in the center of the circular table, allowing extremely precise insert centering within the clamping range of the grinding machine. The new auxiliary measurement system KOMPENSA 3D can numerically measure complex geometries, and perform three-dimensional measurement data by operation, so as to obtain the cut-in width or measure the thickness of the workpiece in the machine.
