2 Universal High-Performance with a double-groove and variable helix The NB-NVD high-performance milling cutter with patented double-groove geometry and variable helix is designed for use in high-performance cutting, where the greatest demands are placed on process security. In contrast to conventional roughing cutters, these milling tools are also suitable for processes that are optimized and place high demands on component quality such as shape or positional as well as surface qualities. Compared to conventional tools, significant benefits can be achieved in these target areas, which result in a higher productivity, lower tool costs and improved price-to-performance ratio. The advantages: Extreme metal removal rates in HPC technology with high feed rates and infeeds Universal applicability for roughing and finishing Extreme process security Excellent suitability for trochoidal milling [ 2 ] The features of the NB-NVD milling cutters to be emphasized are their rigidity, stability and the resistance to tool failure as a result of breakage in connection with the above points. Slot end mills as well as contour milling cutters with the highest feed rates still cannot compete with this tool. The NB-NVD can also be used for simple finishing operations. Users appreciate these features so much that such tools are preferred for modern dynamic milling strategies like trochoidal milling, process security and at the same time, high metal removal rate. Using NB-NVD tools enables you to reach these targets without difficulty, which has a positive impact on the machining and tool costs. % conventional Fig. 2: At least a 30% higher material removal rate with NB-NVD Double-Groove Geometry Material: Ck45 (1.1191), Rm=700N/mm 2, dry +30% NB-NVD The NB-NVD tools distinguish themselves from conventional, smooth-edged solid carbide milling tools by their patented double-groove geometry and variable helix. Both geometric elements ensure the tool s high rigidity and resistance to breakage. High metal removal rate When using the NB-NVD, significantly higher infeeds can be selected compared to conventional tools. This advantage can mainly be attributed to the double-groove critical geometry. This enables an increase of the metal removal rate by 30%, which leads to a significant reduction of the machining costs. This considerable cost reduction can be achieved in not only the machine run time but also in the reuction of machine idle time as well. 1. Groove Geometry 2. Groove Thanks to the double-groove concept, roughing and finishing geometries can be combined in one tool The first face recess ensures the highest metal removal rates and tool life Various materials can be processed by means of the same tool concept (universality) Fig. 4: Double-groove concept Overall geometry Groove, on the end face
