LCS 303

The 3-axis LCS 303 is a precise and reliable laser cutting system capable of processing a wide variety of materials, from metals to ultra-hard and brittle materials such as diamond or ceramic, to complex composites. Applications include high precision machining of medical devices, tools, electronics and other high-tech parts.

The machine with a working area of 300 x 300 mm uses linear motor axes. The work piece is fixed on a T-Nut table. An optional B rotary axis can be mounted on the table allowing to position the work piece with a different rotation angle.

The state-of-the-art CNC machine system includes a high-power green laser, a compact high-pressure water pump with an ultra-pure water unit, a touch-screen control panel and a vision system with motorized zoom.

The automated offset calibration system integrates laser-nozzle alignment, jet angle correction, laser power measurement and jet stability control (all optional).

Materials

Diamond materials: Stainless steel, Durnico, Phynox, CuBe, copper, brass, gold, aluminium, shape-memory alloys (Nitinol, cobalt-chrome), titanium, nickel, superalloys etc.  

Metals and alloys: Polycrystalline CBN (PcBN), polycrystalline diamond (PCD), single crystalline diamond (SCD), CVD diamond, natural diamond, tungsten carbide (WC)  

Ceramics: Silicon carbide (SiC), silicon nitride, (SiN), ceramic-matrix composites (CMCs), CFRP, Zirconia, (ZrO2), HTCC/LTCC, aluminium nitride (AlN), aluminium oxide (Al2O3)

Operations

2D cutting, drilling, slicing, slotting, grooving, trenching, milling, engraving, profiling

 

Key Benefits

  • Sharp and Smooth
    • Smooth cutting surfaces and sharp edges (Ra as low as 0.15 µm)
    • Cylindrical beam resulting in parallel kerfs (no V-shape)
    • Virtually no heat impact thanks to water jet cooling capability
  • Fast and Accurate
    • Cutting of 4 mm CVD diamond in 5 mm/min.
    • High mechanical precision with a tolerance of less than +/- 5 µm
    • Very small kerf width (down to 30 µm)
  • Clean and Easy
    • Clean surfaces and no depositions
    • No or very little post treatment required
    • No focus control necessary due to long working distance
