Description
Light Cutter: Advanced Laser Cutting Solutions for Precision and Efficiency
The Light Cutter series, including the manual LightCutter and motorized LightCutter Motorized, represents PRECITEC’s state-of-the-art offering for economic middle-power laser cutting. Designed with proven Lasermatic© distance sensor technology and high-quality fused silica optics, these systems deliver exceptional performance—supporting max laser powers of 3 kW (LightCutter) and 4 kW (LightCutter Motorized) with wavelengths of 1030–1090 nm.
Their lightweight, compact, and dust-proof design ensures long-term stability, while tool-free protective window cartridges and dual upper/lower protective windows simplify maintenance and protect critical optical components. Ideal for diverse applications, the Light Cutter series caters to both flatbed and 3D cutting needs, handling materials like mild steel (up to 20 mm), stainless steel, and aluminum with smooth, burr-minimal edges. Whether for high-speed 2D cutting or precise 3D tube processing, the Light Cutter adapts to custom configurations, making it a versatile choice for modern manufacturing workflows.
Key Features of Light Cutter
- Integrates high-quality fused silica optics optimized for 1030–1090 nm wavelengths, ensuring low reflection and minimal focal shift
- Equipped with proven Lasermatic© distance sensor for constant workpiece distance, fast response, and drift-free performance (temperature and plasma resistant)
- Tool-free protective window cartridge for quick, easy maintenance without additional tools
- Upper and lower protective windows to fully shield the optical system and prevent contamination during fiber plugging
- Lightweight and compact design (3.3 kg for LightCutter, 4.0–4.4 kg for LightCutter Motorized) enabling high dynamic performance
- Dust-proof and robust construction for long-term stability in industrial environments
- Manual or motorized vertical adjustment: manual version offers calibrated scales for precision; motorized version provides fast, remote control via I/O or fieldbus interface
- 3D-compatible version (with Ff150 focal length) for tube, 2.5D, and 3D cutting, featuring a slim sensor insert with minimal interfering contour
- Status LED (motorized version only) for clear visual feedback—green for successful focal position, red for errors
- Supports multiple fiber sockets (QBH, D) and optical configurations (straight/angled paths, various collimation/focusing focal lengths)
