CNC Erosion Machine for PCD Tools – QR 270

Disc erosion machine for PCD circular saw blades

Design and Structure of the Machine
On the QR the PCD circular saw blades are machined on the top surfaces of the tooth tip. The saw blades are mounted in the vertical position to allow machining of very large diameters (up to 840mm) without restricting the accessibility of the working area. The copper-tungsten rotary electrode is positioned so that erosion is performed with the face of the cup wheel. The face of the electrode is used to achieve precise accuracy at the cutting edge with clearly defined angles – a major advantage for the cutting performance of the saw blade. The machine incorporates a polymer concrete block on which are mounted the operating components for the 8 CNC axes.
