Diamond Tooling For Machining Hard Materials
Horn is presenting in the expo area at this year’s Intec Connect online machine tool and metalworking show, which is normally held at the Leipzig fairground, an expanded range of CVD (chemical vapour deposition) diamond-tipped tooling for cost-effective drilling and countersinking of sintered carbides and ceramics of hardness up to 3,000 HV. They enable short throughput times, high surface quality, low costs and more flexibility within the production process as well as long tool life.
The DDHM tool system allows rigorous machining processes to be carried out on conventional milling and turning centres, eliminating the need to invest in expensive new machinery or resort to costly, time-consuming grinding and eroding processes. Due to their ability to machine carbide punches and dies efficiently, the cutters are particularly suitable for use in the tool and die making sector. However, they also offer production advantages in the medical, aerospace and automotive industries.
The CVD-D-tipped drills are ideal for producing holes in solid material to a maximum depth of ten times diameter. They are of two-edged design and are available in diameters ranging from 2 mm to 10 mm. All versions feature internal channels for cooling with air. For chamfering and countersinking, Horn offers CVD-D end mills with diameters of 3 mm and 6 mm and with flank angles of 15, 30 and 45 degrees. The 3 mm version has five teeth while the 6 mm version has six.
