Ewag Laser Line Ultra keeps focus on CVD tooling
The Laser Line Ultra, available from Walter Ewag UK, uses short-pulse 50 W laser technology to produce the complex contours and chipbreaker designs, as well as 3D cavities, being demanded increasingly by users of CVD diamond tooling.
With 3-axis (U,V,W) laser beam guidance complementing a 5-axis (X,Y,Z,B,C) kinematic machine concept, the machine can process tool cutting edges as well as chipbreakers in a single set-up. An integrated 3D measuring probe is used to calibrate the brazed diamond plates.
According to Ewag, the laser vaporises tooling materials without significant heat input (cold ablation) and, compared with tool grinding and eroding, does not require coolant supply. Its beam path is encapsulated in a protected atmosphere under slight over-pressure to keep it from external influences. A 6-axis articulated arm robot is used for automatic load/unload, which operates in conjunction with two pallets, as standard.
