New chip formers enhance grooving system
With the Walter Cut MX, the Tübingen-based company says it has designed a tool for grooving and parting off that retains all the best elements from earlier systems while also eliminating their weaknesses. The indexable inserts each boast four precision-ground cutting edges, the three chip former types GD8, CF5 and RF5 as well as the new Tiger-tec Silver PVD cutting tool materials.
The manufacturers highlight the merits of the self-aligning, tangential clamping system and the dowel pin location in the insert seat that provide stability and thus allow for high repeat accuracy and process reliability. This also serves to prevent the inserts from being incorrectly fitted. The exceptionally effective chip control offered by the CF5 sintered chip former geometry reportedly makes the new solution a good choice for many different users. Cutting depths of up to 6 mm and cutting widths of between 0.8 and 3.25 mm are available in the standard range. Non-standard sizes and versions are also available via Walter Xpress. Due to the highly precise centre height and the precision-ground cutting edges, the system is seen as ideal for precision grooves, circlip grooves and small diameters. As the German exhibitors point out, the efficiency of the system is such that only one type of cutting insert is required for both the left- and the right-hand tool holder. Moreover, if one of the cutting edges breaks, work can be continued with the rest.
