HELITRONIC DIAMOND EVOLUTION from WALTER is an advanced tool eroding machine with C.O.R.E. technology, developed to both erode and grind tools in a single clamping. The machine is a highly efficient solution for manufacturing and machining tools in PKD/PCD and CBN, while it can also sharpen tools in HSS and cemented carbide.
With its compact design, the HELITRONIC DIAMOND EVOLUTION offers high capacity in a small footprint. The machine handles tools with diameters from 1 to 165 mm, tool length up to 255 mm and workpiece weight up to 30 kg.
Erosion and grinding in one process
HELITRONIC DIAMOND EVOLUTION makes it possible to combine EDM and grinding in the same machine and in the same clamping. This results in high precision, shorter handling time and better conditions for efficient production of complex tools.
Stable cast iron gantry construction
The machine is built according to WALTER's stable cast iron gantry design. The design has good damping properties, which contribute to smooth machining, high accuracy and very fine tool surfaces.
Laser Contour Check for non-contact measurement
HELITRONIC DIAMOND EVOLUTION is available with the new optional feature Laser Contour Check. It is an intelligent measuring system integrated directly into the tool grinding and eroding machine. The system enables highly accurate, non-contact measurement of various tool parameters on cylindrical tools.
Fast linear shafts with ball screw
The machine is equipped with three linear axes, X, Y and Z, with ball screw. The maximum speed of movement is 15 m/min, which provides efficient processing and contributes to short cycle times.
Belt-driven HSK 50 spindle
HELITRONIC DIAMOND EVOLUTION has a HSK 50 belt-driven spindle with two spindle ends. It can be equipped with up to three electrodes and three grinding wheels, or up to six grinding wheels. This provides high flexibility when machining different tools, geometries and materials.
Fine Pulse Technology for high surface finish
The machine is equipped with the latest erosion technology by Fine Pulse Technology. The technology provides a stable and fast erosion process, very fine surface finish and minimal chipping, which is particularly valuable when machining PCD/PCD and CBN tools.
