Based on a highly efficient and productive two-in-one concept, Walter Helitronic Vision Diamond 400 L, Helitronic Power Diamond 400 and Helitronic Diamond Evolution tool grinding machines, from United Grinding North America Inc., integrate both eroding and/or grinding capabilities into single grinding machine platforms. From a production standpoint, the two-in-one concept lets users completely erode tools (PCD) and completely grind tools (carbide) using the same machine to eliminate the time-consuming task of moving workpieces to a second machine.
