Turning with form tools allows customers to benefit from economic advantages in series production. Horn offers customised carbide form inserts based on the 117 tool system for machining diameters from 16 mm upwards on turning and mill-turn centres. The patented, precision insert seat of the 117 system guarantees high concentricity and minimal axial runout as well as high repeatability of insert exchange to within microns. The precision-ground cutting edges achieve a high level of accuracy and surface quality. Financial savings are achieved due to the possibility of re-tipping, lower tool costs and reduced machine downtime. The internal coolant supply to both cutting edges via the round shank cools the contact zone and carries the chips away efficiently.
Horn offers the tools in profile widths (w) of 16 mm, 20 mm and 26 mm. Special profiles are precision ground to suit the application. The maximum profile depth is tmax = 17 mm. The maximum profile width is w = 26 mm. The insert coating is specially selected for each application and is available for material groups P, M, K and N. The round shanks are available as standard with diameters of 16 mm, 20 mm and 25 mm in the A and E designs. All variants have an internal coolant supply.
