The Walter Helitronic Raptor from United Grinding is designed for grinding and resharpening rotationally symmetrical tools for the metal and wood industries. The machine is said to be 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 Helitronic Raptor has a 15.4-hp (11.5-kW) spindle and a work envelope that can accommodate tools ranging to 12.6" (320 mm) in diameter and 11.0" (280 mm) in length, including end face operations. The machine is equipped with Walter’s Helitronic Tool Studio CAD/CAM software for tool design, part production and resharpening tasks. 

Featuring a low-vibration gray cast iron frame and gantry-type construction, the machine accommodates a range of optional components, including top loaders with up to 500-tool capacities integrated in the working area. Other options include glass scales, A-axis torque drive, grinding wheel measuring probe and manual support steady rest.
