Shine On with Two-in-One Part-Production, Re-Sharpening

Resharpen carbide or PCD tools in metalcutting applications with the Walter Helitronic Raptor Diamond from United Grinding Group (Miamisburg, Ohio), designed with grinding and eroding technology that gives users plenty of flexibility.

Its Fine Pulse Technology achieves low cycle times and better performance for producing tools with smoother exteriors and cutting edges, along with super-fine finishes comparable to the visible shine generally reserved for polished tools. Fine Pulse Technology finely finishes tools made from the most common PCD types, from 10 µm grain size to coarse-grained formulations.

Developed especially for the re-sharpening and production of rotationally symmetrical PCD tools, the Walter Helitronic Raptor Diamond benefits shops that don’t require automatic tool support systems or automatic grinding wheel/electrode changers but still need a high degree of flexibility in the working area for diverse types of tools.

The Helitronic Raptor Diamond has a 15.4 hp (11.5 kW) spindle and a work envelope that can accommodate tools up to 15.7″ (400 mm) in diameter and 10.6″ (270 mm) in length, including end face operations. As with other Walter Two-in-One EDM and grinding machines, HSK interface for electrode/wheel grinding is standard.

The machine uses Walter Helitronic Tool Studio for the utmost in tool grinding and eroding efficiency, from tool design to part production, as well as re-sharpening.

In addition to its low-vibration gray cast iron frame and gantry-type construction, the Helitronic Raptor Diamond is designed to accommodate a range of options, including top loaders with up to 500-tool capacities integrated in the working area. Other options include glass scales, A-axis torque drive, a grinding wheel measuring probe and a manual support steady rest.
