Precision mechanics

Micro-drilling, cutting and texturing with micron tolerances and no burrs. Parts come off the machine finished, without deburring or post-polishing.

Deburring steps after laser processing.

From problem to process

Small parts, tight tolerances. No room for burrs.

  1. 01 · Problem

    Post-processing eats the margin

    Mechanical micro-drilling breaks tools and leaves burrs. Nanosecond lasers melt the material, leaving recast, heat-affected zones and debris that need extra cleaning and inspection steps.

  2. 02 · Requirement

    What the process needs

    • Burr-free edges with no recast layer
    • Micron-level dimensional accuracy
    • Metals, ceramics and polymers on one machine
    • Stable quality from first part to last

  3. 03 · Process

    Ablation without melting

    Each femtosecond pulse removes a thin layer of material before heat can spread. Holes, slots and contours are cut layer by layer, with clean walls and no melt at the edge.

Why the architecture fits

Compact laser head

Integrates into small micromachining stations and multi-axis cells.

Passive air cooling

No chiller to install or service, so the station stays small and simple.

Stable pulse energy

Pulse-to-pulse stability keeps hole size and depth consistent across a shift.

Simple integration

CAN and USB control, TTL pulse-picker gating and an analog power input for PLC, CNC or custom controllers.
