The Walter Helitronic Raptor from United Grinding Group is a flexible, cost-effective tool grinding solution. Created for the grinding and re-sharpening of rotationally symmetrical tools, the Heltronic Raptor offers both automation-ready flexibility and an economical, universal design for all-around tool grinding excellence.

Developed with the re-sharpening sector of the rotationally symmetrical tool market in mind, the Walter Helitronic Raptor is particularly 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. The new machine ensures that manufacturers have access to Walter quality with exactly the features they need for part-production and re-sharpening success.

The Helitronic Raptor has a 15.4hp (11.5kW) spindle and a work envelope that can accommodate tools up to 12.6" (320mm) in diameter and 11.0" (280mm) in length, including end face operations. For the utmost in tool grinding efficiency, from tool design to part production as well as re-sharpening, the machine uses Walter Helitronic Tool Studio.

In addition to its low-vibration gray cast iron frame and gantry-type construction, the Helitronic Raptor 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.
