DMG Mori LASERTEC 20 PrecisionTool

The DMG Mori LASERTEC 20 PrecisionTool is a 5-axis laser processing center built specifically for manufacturing and resharpening PCD (polycrystalline diamond), CVD diamond, CBN (cubic boron nitride), and carbide cutting tools. Where conventional grinding of PCD tools is slow, creates poor edge quality, and wears diamond wheels at punishing rates, the LASERTEC 20 PrecisionTool uses a pulsed fiber laser to cut and shape these ultrahard materials without mechanical contact.

Travel sits at 200 x 200 x 200 mm (7.9 x 7.9 x 7.9 in) on the linear axes. The A-axis tilts +/-110 degrees and the C-axis rotates 360 degrees continuous, providing full angular access to cutting edges, chip breakers, and rake faces. Positioning accuracy is 1 micrometer with repeatability under 0.5 micrometers -- the kind of precision that PCD tool geometry demands.

The fiber laser delivers up to 200 W of average power with nanosecond pulse durations. For PCD tools, the laser ablates the diamond material along programmed edge profiles, creating sharper cutting edges than grinding can achieve. Edge radii down to 2 micrometers are standard, with surface roughness on the rake face under Ra 0.2 micrometers. The laser also cuts complex chip breaker geometries that would be impossible to grind.

The machine comes with dedicated tool-making software that imports standard tool geometry formats and generates laser paths automatically. An integrated tool measurement system uses a vision camera and touch probe to align tools before processing and verify geometry after. The compact footprint of approximately 2 x 2 meters makes it suitable for tool rooms and small production cells.

PCD insert production, tool resharpening, and prototype tool development are the primary applications. The machine handles round tools up to 200 mm diameter and indexable inserts of all standard geometries. Pricing typically falls in the 00,000 to 00,000 range.
