The WBM 205 CDR is based on the WBM eco and has recently developed a self-rotating workpiece support surface, which is especially suitable for grinding single and double ends of superhard materials. The two workpieces on the rocking table of the grinding machine drive the supporting surface and can rotate while rocking. The advantage of this grinding method is that the flatness and parallelism of the blade are extremely high, below 2μm, and the surface of the blade surface is very fine, the surface The roughness is below 0,1μm, which is close to the polishing range. With the continuous online dressing system ROTODRESS, the fine-grain grinding wheel is always evenly sharp, achieving the highest dimensional and topographical accuracy. The new design also makes the grinding machine WBM 205 CDR more compact and practical.
The Vantage 5-axis CNC Grinding Center WAC 735 CENTRO's "360° x 360°" axis motion principle and innovative flexible fixture design enable a single clamping, all-round machining of the periphery, groove, cutting groove and negative Chamfer. With the theme of processing modern new materials, we have used the disc-shaped coarse-grained, bowl-shaped fine-grain combination grinding wheel for the first time to efficiently grind the perimeter of the PCD insert. First, when the blade is coarsely ground, the wheel line contacts the workpiece, which reduces the grinding pressure and improves the coolant entering the contact area between the grinding wheel and the workpiece, thereby significantly improving the quality of the cutting edge. After rapid rough grinding, the grinding machine can be ground with a bowl-shaped grinding wheel at a large blade adjustment angle, with the grinding direction at a variable angle to the cutting edge for maximum edge quality. The newly developed C-clamp AXR has axial and radial support, which greatly enhances the rigidity when grinding PCD. Due to the use of a disc-shaped grinding wheel, it also needs to be trimmed, so the grinding machine adds a high-precision dressing shaft.
The Vantage 4-axis CNC Peripheral Grinding Center WAC 715 QUATTRO is ideal for high-efficiency grinding of cutting tools such as indexable inserts for minimum grinding times and minimum assist times, as well as maximum use. As an upgraded version of the WAC 715 SCALAR, a grinding machine commonly used worldwide, the WAC 715 QUATTRO has the same basic construction as the 5-axis grinding center WAC 715 CENTRO. The main innovation of the grinding machine is the use of hydrostatic bearings. By increasing the rigidity and shock resistance, even super-hard materials can be processed at high speed, while achieving no chipping and highest cutting edge quality. Compared to previous grinding machines, there is also an innovation: the expansion of the feed axis (X-axis) stroke, which greatly increases the processing range of the grinding machine. The central prism is integrated into the center of the circular table, making the blade extremely accurate in the centering range of the grinding machine. The new auxiliary measuring system KOMPENSA 3D can numerically measure complex geometries and calculate 3D measurement data to obtain the cutting width or the measured workpiece thickness in the machine.
After grinding the end face and the periphery of the CBN and PCD blades, the SPECTRA 820 laser can be used to machine the three-dimensional complex features of the blade, such as chip flutes and negative chamfers. The laser machine is suitable for high-precision machining of microscopic shapes. A diode-supplied highest quality solid-state laser produces a 20-40 μm diameter concentrating drive with a frequency of up to 100 kHz, ensuring the highest removal rate. Its pulse time is in the nanosecond range, thus avoiding thermal damage to the workpiece. Laser power components can be replaced and easy to maintain. The laser machined workpiece moves under the static laser beam. This innovative shaft design and laser precision focusing, combined with nano-concentration technology, enables micro-machining of three-dimensional shapes. A further advantage is that the machining time is very short, because of the direct drive linear motor, the acceleration can reach 5g. The adjustment, centering, and finished product measurement of the workpiece is done by a measuring head mounted on the machine tool, and the measuring head is also involved in monitoring the machining process. The new modular clamping system allows the user to quickly change the clamping according to different workpieces. The loading and unloading system installed in the machine automatically loads and unloads the workpiece from the tray, and it is easy to connect with the grinding machine and the packaging machine to form a flow operation. The laser machine is programmed through 3D-CAD/CAM memory and can read CAD data of the user's common exchange format, such as IGES or STEP.
In addition, based on the innovative slot filtration principle, the cooling system FLUIDMASTER 730 achieves ultra-pure filtration. The system is compact in construction, small in floor space, self-closing work, can be connected to different machine tools, and even can be supplied to multiple grinding machines.
As a grinding system supplier, in addition to providing grinding machines, accessories, cooling systems and application technology, Vant offers grinding tools that are ideal for grinding superhard materials, especially for grinding PCD and CBN, the newly developed MATRIX series. The grinding wheel has excellent grinding performance during high-speed feed, and at the same time achieves excellent cutting edge, together with the best matching high-precision wear-resistant diamond dressing roller, the complete set provides perfect grinding solution.
