Software The intelligence of tool machining and measuring for production and regrinding The WALTER grinding software HELITRONIC TOOL STUDIO and the EWAG grinding software ProGrind are based on decades of experience and market-proven tool grinding expertise. With its wizard technology, WALTER HELITRONIC TOOL STUDIO guarantees optimal tool machining. In a very short amount of time, grinding programs for very complex tool geometries can be programmed. HELITRONIC TOOL STUDIO What you see is what you grind. EWAG ProGrind is tailor-made for flexible use. Thanks to input masks with 3D graphics, it is possible to create individual grinding programs quickly and easily. Via 3D simulation, the grinding program can be analysed at any time and corrected as necessary. The variety of WALTER measurement technology software matches the HELICHECK CNC measuring machines perfectly and offers innovative and user-friendly functions.
