1390 High-Precision Laser Cutting Sheet Machine | Accuracy ±0.03mm

Description

When “Close Enough” Is Not Good Enough

You cut thin sheets – 0.5mm, 1mm, 2mm. Maybe you make electronic enclosures, medical device prototypes, decorative metal art, or precision gears. Your parts have tight tolerances. They need to fit together without filing, grinding, or rework.

You’ve tried other cutting methods:

• A standard CO₂ or fiber laser – good, but cuts are often ±0.1mm or worse. That’s fine for structural steel, but not for parts that interlock.

• Waterjet – precise, but slow, messy, and expensive to run.

• EDM (wire cutting) – extremely accurate, but painfully slow and requires conductive materials.

• Punching or stamping – accurate, but requires expensive tooling and is only economical for high volumes.

• Hand cutting – impossible for tight tolerances.

You need a machine that delivers real, repeatable accuracy – not just on the spec sheet, but on your actual parts.

The 1390 high-precision laser cutting sheet machine is built for exactly that purpose. With a guaranteed accuracy of ±0.03mm, it’s designed for shops that can’t afford to scrap parts or spend hours deburring and adjusting.

1390 High-Precision Laser Cutting Sheet Machine – Accuracy You Can Trust

The “1390” in the model name refers to the working area: 1300mm × 900mm – a compact, benchtop-friendly size that’s perfect for small sheets, panels, and intricate parts.

What makes it “high-precision”?

• High-resolution servo drives – 0.001mm positioning resolution.

• Rigid, stress-relieved frame – minimizes vibration and thermal expansion.

• Precision linear guides – zero backlash for consistent motion.

• Fine-focus laser head – spot size as small as 0.05mm.

• Closed-loop motion control – real-time feedback ensures the machine stays on track.

The result: ±0.03mm positioning accuracy and ±0.02mm repeatability. That’s about the thickness of a human hair (0.06mm). Your parts will fit together perfectly – every time.

Key features:

• Laser power: 100W CO₂ or 100W/200W fiber (you choose based on materials)

• Working area: 1300×900mm – ideal for small to medium sheets.

• Cutting thickness: Up to 5mm (mild steel), 3mm (stainless), 10mm (acrylic/wood)

• Simple, intuitive control – no need for a dedicated programmer.

• Compact footprint – fits in any workshop, lab, or even a garage.

This is not a production machine for cutting 10,000 parts a day. It’s a precision tool for shops that prioritize quality over quantity – prototyping, custom fabrication, short-run production, and high-mix low-volume work.

Applications of the 1390 High-Precision Laser Cutting

Arts, Crafts, and Jewelry

Industry Demands: Cutting and engraving intricate patterns in wood, leather, acrylic, and precious metals (gold, silver, brass) for custom jewelry, decorative artworks, personalized gifts, and small accessories.

Reasons for Selection: The machine offers the fine detail and delicate touch required for artistic works. It can engrave textures and cut complex, delicate shapes, providing artists and jewelers with a powerful tool to realize their designs.

Gasket and Seals Manufacturing

Industry Demands: Precision cutting of thin gasket materials (rubber, cork, fiber, foam) for industrial and automotive applications.

Reasons for Selection: The 1390 cuts these materials quickly and accurately without tooling costs, making it ideal for both prototype and short to medium-run production of custom-shaped gaskets with smooth, burr-free edges.

Medical Device Prototyping

Industry Demands: Prototyping and small-batch production of surgical instruments, diagnostic equipment housings, implantable device components, and fluidic connectors from stainless steel, titanium, and medical-grade polymers.

Reasons for Selection: The high precision and material compatibility allow for the rapid creation of intricate, contamination-free parts with smooth edges, critical for meeting medical standards. The ability to cut both metals and polymers with different laser sources makes it a versatile tool for R&D

FAQs

1. What types of materials can the 1390 high-precision laser cutter process?

The 1390 is available in two configurations:

• CO₂ Version: Ideal for non-metals, including acrylic, wood (plywood, MDF, solid wood), leather, paper, cardboard, fabric, rubber, and some plastics. It can also mark glass and anodized aluminum.

• Fiber Version: Designed for metals, including stainless steel, carbon steel, aluminum, brass, copper, and titanium. It can also engrave some plastics and coated metals.

2. What are the primary advantages of the 1390 over larger industrial machines?

• High Precision: It delivers ±0.03mm accuracy, which is comparable to or better than many larger, more expensive machines.

• Compact Footprint: Its 1300×900mm bed size and desktop-friendly dimensions are ideal for workshops, labs, and studios with limited floor space.

• Versatility: It can process a wide range of materials by simply choosing the appropriate laser source and adjusting parameters.

• Cost-Effective: It offers a lower initial investment and operating cost, making precision laser technology accessible to smaller businesses and individual professionals.

3. How is the ±0.03mm accuracy achieved and verified?

The accuracy is achieved through a combination of:

• High-Rigidity Design: The stress-relieved, heavy-duty machine bed provides a stable, vibration-free platform.

• Precision Components: High-quality, precision-ground linear guides and zero-backlash transmission systems ensure accurate motion.

• Fine-Focus Optics: The laser cutting head focuses the beam to a very fine spot, enabling precise material removal.
  Each machine is calibrated using a laser interferometer at the factory to verify and ensure its stated performance.

4. Is it difficult to switch between cutting and engraving modes?

No, switching between modes is simple and quick. The control software allows you to select cutting or engraving mode and adjust the corresponding parameters (power, speed, frequency) for the job. The machine can perform both functions in a single operation, such as engraving a design and then cutting out the outline, without any manual intervention.
