Ultimate precision and dynamic performance in volume production of tools with a length up to 420 mm

The HELITRONIC VISION 400 L is the next generation of the globally established HELITRONIC VISION. An even more rigid mineral cast machine bed with very good vibration dampening ensures that the highly dynamic drive acts optimally on the grinding wheel and its extremely low temperature sensitivity makes the grinding process particularly stable. The highprecision CNC tool grinding machine can grind lengths of up to 420 mm on the perimeter and provides optimum conditions for grinding rotationally symmetrical tools in production and/or resharpening facilities.

The HELITRONIC VISION 400 L produces rotationally symmetrical tools and production parts with complex geometries in series with a high level of precision. Permissible diameters up to 315 mm, tool lengths up to 420 mm and weight up to 50 kg.
