Larger depths of cut (up to 3.3 mm) and feed per tooth can be achieved, says WNT. By way of example, a recent trial involved the machining of Ti6Al4V titanium alloy components. Here, a 63 mm diameter WNT HFC 19 cutter was run at 0.71 mm feed/tooth, compared with 0.25 mm for the competitor cutter, achieving a cycle time of 52 minutes instead of 120 minutes (a saving of 57%). Tool life was also increased by 200%, with one set of cutting edges machining three components, compared to just one component using the competitor cutter.
HFC 19 cutters enable machine shops to plunge mill, face mill, circular/freeform mill and take on intermittent cutting, all with the same tool and inserts. Customers have a choice of insert geometry, with -F40 positive geometry being suitable for the finish and rough machining of heat resistant materials such as titanium and super alloys. The -M50 geometry is WNT’s universal geometry for light to medium roughing of steel components.WNT HFC 19 cutter reduces cycles by up to 57%

The new HFC 19 indexable insert milling system from Ceratizit WNT targets high chip volume applications that demand elevated process security. According to the company, milling cycle times can be reduced by as much as 57%, thanks to the insert geometry, WNT Dragonskin coating and cutter body design. The inserts have a patented rectangular edge geometry and a large corner radius that delivers a combination of rigidity and soft cutting, reducing stress on the machine spindle. A further benefit is that cutting forces are in the axial direction, which helps to minimise noise levels.
