Walter Helitronic Raptor Tool Grinder Resharpens Rotationally Symmetrical Tools
The Walter Helitronic Raptor from United Grinding is designed for grinding and resharpening rotationally symmetrical tools for the metal and wood industries.
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.
Because of the high material removal rate creep-feed grinding can deliver in challenging materials, grinding might not be just the last step in the process—it might be the process.
No other process can do what creep-feed grinding can do. Recent tests show even more can be gained by optimizing every element of a creep-feed system.
Two enabling technologies -- superabrasive wheels and high precision servo control -- come together to provide a contour grinding process that resembles an OD turning operation. For many medium volume OD grinding applications, this method may be a means to consolidate several manufacturing steps into a single setup.
