Inovatools new Curvemax series of curve segment cutting (CSC) mills, set new standards in copy milling. The new universal VHM curve segment mills in tangential and conical form shorten the process times required for finishing complex, freeform surfaces in a wide variety of materials — such as for aluminum cutting in the aeronautical industry. Curvemax mills also enhance the surface quality compared with standard, full-radius mills.
The developer predicts that, compared with conventional ball-shaped mills, the new Curvemax tools used in the same application can achieve time savings of up to 90%, up to 60% improved surface quality and an up to 90% longer service life.
Thanks to their special geometry, the new mills permit larger path distances and line jumps during pre-finishing and finishing. Although the working radius is larger than that of a traditional full-radius mill, the tool still has the same diameter. This leads to a significant reduction in process times. Thanks to the larger engagement width, the cutting edge does not suffer from wear at any point. Combined with the extremely smooth, high-performance Varocon coating, this helps to increase the tool's service life. The larger and flatter overlap reduces roughness and ensures surface finishes even better than those created by traditional full-radius mills. Inovatools offers the new CSC-Curvemax mills in conical and tangential form as four-edged cutters for finishing in different sizes and radii.
The following real-life example underlines the performance of the Curvemax: While a conventional ball-shaped mill (Ø 6 mm; line distance: ae 0.17 mm) takes 14:53 minutes to finish a workpiece made of tempering steel 1.2379, the Curvemax (conical form; line distance: ae 2.20 mm) takes only 2:34 minutes for the same workpiece. The average raw value with the ball-shaped mill was 0.8 µm – with the Curvemax, it was 0.5 µm.
Thanks to their curve segment milling technology, the Curvemax mills also open up new production methods, e.g., to reliably create undercuts, freeform surfaces and variable setting angles. In addition, complex contours can be pre-finished and finished, even on narrow inside radii.
