New Tool Grinding Solutions



UNITED GRINDING Group's WALTER HELITRONIC RAPTOR and HELITRONIC RAPTOR DIAMOND tool grinding solutions are designed for the grinding and resharpening of rotationally symmetrical tools for the metal industry. The new HELITRONIC RAPTOR offers both automation-ready flexibility and an economical universal design for enhanced all-around tool grinding applications. The new WALTER 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 metalcutting applications.

Developed with the resharpening sector of the rotationally symmetrical tool market in mind, the WALTER HELITRONIC RAPTOR is particularly 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 resharpening success," said a company spokesperson.

The HELITRONIC RAPTOR has a 15.4 HP (11.5 kW) spindle and a work envelope that can accommodate tools up to 12.6" (320 mm) in diameter and 11.0" (280 mm) in length, including end face operations. For enhanced tool grinding efficiency, from tool design to part production as well as resharpening, the machine uses WALTER HELITRONIC TOOL STUDIO.

"For the HELITRONIC RAPTOR DIAMOND, WALTER eroding technology achieves low cycle times and better performance due to FINE PULSE TECHNOLOGY, which produces tools with smoother, more perfect exteriors and cutting edges along with super-fine finishes that match the level of visible shine generally reserved for polished tools," said the spokesperson. "FINE PULSE TECHNOLOGY finely finishes tools made from the most common PCD types, from 10 µm grain size to coarse-grained formulations."

Developed for the resharpening and production of rotationally symmetrical PCD tools, the WALTER HELITRONIC RAPTOR DIAMOND is 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 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. Like other WALTER Two-in-One EDM and grinding machines, an HSK interface for electrode/wheel grinding is standard. For enhanced tool grinding and eroding efficiency, the machine uses WALTER HELITRONIC TOOL STUDIO.

In addition to low-vibration gray cast iron frames and gantry-type constructions, both the HELITRONIC RAPTOR and HELITRONIC RAPTOR DIAMOND are 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.
