Horn is releasing an expanded range of CVD (chemical vapour deposition) diamond-tipped tooling for the cost-effective drilling and countersinking of sintered carbides and ceramics of hardness up to 3000 Hv. According the company, the tools 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 take place 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 suitable for producing holes in solid material to a maximum depth of 10xD. Each tool is of two-edged design and is available in diameters ranging from 2 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 and 6 mm, and with flank angles of 15, 30 and 45°. The 3 mm version has five teeth, while the 6 mm variant has six.
