Walter has unveiled two brand new Helitronic models at this year's
GrindTec industry trade show: the Helitronic Power 400 grinding machine and the Helitronic Power Diamond 400 grinding and eroding machine. Walter's latest machines feature a grinding wheel / electrode changer and extended traverse, and can now machine tools up to 380 mm in length, surpassing the previous limit of 280 mm. This is an increase of over 35 percent. But the two machines offer more than just longer workpiece lengths. Walter engineers completely redesigned
the Helitronic Power and Helitronic Power Diamond multi-functional
machines. "The new Helitronic Power 400 and Helitronic Power Diamond 400 machines are more in line with our Helitronic Vision models. They're basically two completely new machines," says Torsten Wörner, product manager in the grinding department at Walter. For example, the base of both machines was completely remodelled. The new, more rigid machine bed ensures even better damping behaviour
which in turn facilitates greater precision and higher surface quality. The C-axis of the standard version of both new machines is driven by a worm drive. A low-maintenance and extremely accurate torque motor is also available as an optional feature.
