Tool Manufacturing

System offers fast and accurate laser machining solutions for the tool manufacturing industry.

Laser MicroJet (LMJ) systems are able to cut a wide range of materialssuch metals, ceramics, ultra-hard materials and carbide substrates as well as non-conductive materials such as SCD.

The laser cutting systems with 3 axes are ideal for
2D cutting, drilling, grooving or slicing of PCD, MCD, PcBN or CVD diamond tool bits, leaving, smooth cutting surfaces and sharp edges.

The 5-axis machines enable high-precision 3D ablation (shaping) for cutting single or multiple clearance angles and chamfering K-land edges. Furthermore, the LMJ technology allows homogeneous step-free cuts between diamond layer and carbide.

All machines are based on hybrid water jet/ laser method (LMJ) that combines the advantages of water and laser cutting into one operation. The laser beam is entirely contained within the water jet as a cylindrical beam, similar in principle to an optical fiber, resulting in perfectly parallel kerf walls. Contrary to results achieved by conventional lasers, wet approach offers a less aggressive cutting process without heat affected zone (HAZ) and micro-cracks that can weaken the material’s fracture strength. Notably, since the LMJ produces damage-free edges it eliminates the need for extra processing steps, such as etching, grinding or cleaning and therefore reducing manufacturing costs.
