WALTER HELITRONIC POWER 400 CNC grinding machine

WALTER HELITRONIC POWER 400 CNC grinding machine built in 2017 in Germany, is designed for fully automatic tool grinding. The grinding process takes place in five axes (X,Y,Z,C,A), on workpieces with a maximum length of 380 mm (end face grinding) or 520 mm (peripheral grinding) and with a weight up to 50 kg. Axis feeds are respectively 650 mm (X axis), 350 mm (Y axis), 720 mm (Z axis), 400° (C axis) and ∞° (A axis).

Superior machining quality and precision is achieved thanks to the machine’s solid grey cast iron construction with increased rigidity, effectively reducing vibrations during the grinding process. The modern design and installed high-end FANUC CNC controller with a large and comfortable to use control panel, significantly distinguishes the grinding machine from the rest of the machines in its class.

The extensive equipment of the CNC grinding machine include among others the RENISHAW MP250 electrostatic probe performing reliable measurements in all conditions, a spindle operating at a maximum speed of 10500 rpm and the CAD/CAM software HELITRONIC TOOL STUDIO for designing and editing all tool parameters. The five-axis CNC grinding machine weighs approximately 5300 kg.
