United Grinding Walter Helitronic Raptor.

United Grinding Group’s Walter Helitronic Raptor and Helitronic Raptor Diamond provide flexible, cost-effective tool grinding.

Created for the grinding and resharpening of rotationally symmetrical tools for the metal and wood industries, the Helitronic Raptor offers automation-ready flexibility and all-around tool grinding. The Helitronic Raptor Diamond further extends the company’s Two-in-One grinding and eroding machine concept for resharpening carbide or PCD tools for use with wood or metalcutting applications.

The Helitronic Raptor is well-suited for shops that do not require features such as automatic tool support systems or automatic grinding wheel changers, but still need a high degree of flexibility in the working area for diverse types of tools. Its work envelope can accommodate tools up to 12.6" (320 mm) in diameter and 11.0" (280 mm) in length, including end face operations.

For the Helitronic Raptor Diamond, Walter eroding technology achieves low cycle times and better performance thanks to fine-pulse technology, which produces tools with smoother exteriors and cutting edges, enabling finishes generally reserved for polished tools. It finishes tools made from the most common PCD types, from 10 micron grain size to coarse-grained formulations.

Developed especially for the resharpening and production of rotationally symmetrical PCD tools, the Helitronic Raptor Diamond is well-suited for shops that do not require features such as automatic tool support systems or automatic grinding wheel/electrode changers, but still need a high degree of flexibility in the working area for diverse tool types. Its work envelope can accommodate tools up to 15.7" (400 mm) in diameter and 10.6" (270 mm) in length, including end face operations. An HSK interface for electrode/wheel grinding is standard.

Both machines have a 15.4-hp (11.5-kW) spindle. In addition to low-vibration cast iron frames and gantry-type constructions, both machines accommodate top loaders accommodating as many as 500 tools.
