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 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.
Advanced grinding equipment gives this shop the flexibility and automation it needs to serve customers with either rapid-response or high-volume jobs.
Achieving consistent and quality results from the centerless grinding process requires an understanding of the basic fundamentals. Most application problems associated with centerless grinding derive from a misunderstanding of the basics. This article explains why the centerless process works and how to use it most effectively in your shop.
It sounds like a contradiction in terms-between centers and centerless grinding on one machine. But for some categories of workpieces, it's a viable production process that can yield machining time reductions of 45 percent over separate grinding operations.
