High Performance Spindle

For certain applications – such as strong 3-D marking on very hard metallic materials or even for the large series – the engraving or milling machines were until now limited by the strength and rotation frequency of the spindle. When it comes to making front faces for electrical equipment, or 3D marking of metallic supports, the optional integration of high performance and high frequency spindles considerably reduces the cycle time, principally by lowering the number of necessary passes. These technologies will therefore become particularly interesting for medium or large series applications. This option addresses engraving machines from the IS range (6000, 7000, 8000) and XP range. While high power and high frequency spindles are standard equipment on the market, Gravograph offers a totally integrated solution. The spindle is therefore controlled by the machine´s electronic control system. Likewise, all the information concerning the spindle is integrated into the control screen of the machine (speed of rotation, charge, etc), and, for further safety, a single switch starts both the machine and spindle. The spindle is driven by GravoStyle5 software, which offers numerous CAD/CAM functions to augment the marking options. The new spindles can be equipped as high-quality tools on the Gravograph range, to obtain the most precise results, even with the demanding 2D, 2.5D and 3D applications. Tools with diameters up to 6mm (1/4») are acceptable. This spindle option is compatible with most Gravograph marking accessories: chip hood, vacuum table that fixes pieces to be engraved by depression, tool changer, etc. Finally, the high power spindles can be installed on kit that is already in service. In this case, the services of a Gravograph technician are necessary.
