-
Hydraulic Safety: Ensure the area beneath the hydraulic platform is clear of obstructions before lowering the table to prevent crushing hazards or mechanical damage.
-
Dust Management: Stone processing generates fine particles. Always operate the centrifugal exhaust fan and wear a mask when cleaning the machine interior.
-
Weight Limits: Do not exceed the maximum rated weight capacity of the hydraulic lift system. Overloading can lead to hydraulic seal failure or frame distortion.
-
Active Cooling: Verify that the water chiller is operational and the flow is steady before firing the laser. Running without cooling will cause the glass laser tube to crack.
VIII. Frequently Asked Questions (FAQ)
Q1: How much weight can the open-chassis hydraulic lift platform handle?
The hydraulic lift system on the YH1390 CO2 Laser Engraving Machine is engineered for the heavy-duty demands of the masonry industry. Unlike standard electric screw-lifts found on hobby machines, which can often only support 20kg to 50kg, our hydraulic system is reinforced to handle stone slabs weighing up to 200kg (depending on specific configuration). The open-chassis design allows the heavy platform to be supported by a robust hydraulic ram located at the base of the machine. This ensures that when you are engraving a large marble headstone or a thick granite slab, the Z-axis remains perfectly stable and level, preventing any focal drift that could ruin a long engraving job. For YIHAICNC customers, this means you can confidently process full-weight industrial materials without worrying about mechanical failure or table sagging.
Q2: Is the YH1390 suitable for photo engraving on dark granite?
Absolutely. In fact, photo engraving is one of the strongest applications for this CO2 Laser Engraving Machine. Dark granite is the ideal substrate for laser etching because the laser beam “blasts” a white mark into the surface, creating a high-contrast image. The Ruida RDC6442S controller allows for precise “Dithering” settings, which are essential for translating the shades of a photograph into a series of laser pulses. When combined with the machine’s weighted frame—which eliminates the tiny vibrations that cause “ghosting”—you can achieve photographic clarity on stone. We recommend using a high-quality BMP file and setting the machine to a lower power and higher speed for the best surface contrast, ensuring that your memorial portraits look professional and life-like every time.
Q3: Why is the weighted chassis important for stone processing?
Stability is the foundation of precision. Stone materials like granite are extremely hard and do not absorb energy like wood or plastic; instead, the mechanical vibrations from the laser head’s rapid direction changes can be reflected back into the machine frame. YIHAICNC applies a weighted treatment to the chassis of the YH1390 to increase its inertia. This extra mass ensures that the machine remains firmly planted on the ground, preventing the frame from “shaking” during high-acceleration engraving tasks. This is what allows our CO2 Laser Engraving Machine to maintain a positioning accuracy of 0.05mm. Without this weighting, you would see wavy lines or blurred text on your stone projects, especially at the corners where the laser head changes direction quickly.
Q4: Can I use this machine as a CO2 Laser Cutting Machine for other workshop materials?
While the YH1390 is optimized for stone engraving, it remains an exceptionally versatile CO2 Laser Cutting Machine for non-metallic materials. By adjusting the laser power and speed, you can easily cut through wood, acrylic, and MDF. This is particularly useful for stone masons who need to create custom wooden boxes for monuments or acrylic templates for decorative stone inlay work. The hydraulic lift platform provides an added advantage here, as it allows you to lower the table to fit large, pre-assembled wooden crates or furniture pieces that need to be engraved. This multi-purpose capability ensures that your YIHAICNC machine remains productive even when you don’t have stone-specific orders in the queue, providing a much faster return on investment.
Q5: What maintenance does the hydraulic lift system require?
The hydraulic system is designed for long-term industrial reliability and requires very little maintenance compared to standard mechanical components. Every 6 months, we recommend a visual inspection of the hydraulic ram and the fluid lines to ensure there are no leaks. You should also check the hydraulic fluid level and top it off if necessary using standard industrial grade hydraulic oil. The most important maintenance for a stone-processing machine is actually “Dust Control.” Because stone dust is abrasive, you must wipe down the HIWIN square rails daily and apply a light coat of lubricant. This prevents the stone particles from entering the bearing blocks, ensuring the YH1390 continues to provide smooth and precise movement for many years of operation in a dusty workshop environment.
Q6: Is the Ruida RDC6442S controller compatible with professional design software?
Yes, the Ruida RDC6442S is the industry standard for CO2 Laser Engraving Machine control. It is fully compatible with LightBurn, which is currently the most popular software for laser operators due to its intuitive photo-processing tools and advanced pathing logic. It also comes with the free RDWorks V8 software, which includes plugins for AutoCAD, CorelDRAW, and Adobe Illustrator. This compatibility means that you can design your stone engravings in your favorite CAD or graphic software and send them directly to the machine. The Ruida system also supports “U-disk” offline work, which is vital for stone workshops where a computer might be kept in a separate, dust-free office while the machine runs in the main production area. This workflow ensures that your production remains efficient and your electronics stay protected.








Thiago Almeida 🇧🇷 (Belo Horizonte, Brazil) –
We do granite headstone engraving in Belo Horizonte and currently use a manual sandblasting setup for lettering. I’m looking at the 1390 stone laser with hydraulic lift to speed up the layout and fine detail work. The open-chassis hydraulic platform seems ideal for loading heavy slabs with a small crane. Can you confirm the maximum weight the hydraulic platform can handle? Also, what’s the engraving depth achievable on black granite with a single pass?
Alex_Zhang –
Thiago, the hydraulic platform on this model is rated for 800kg—comfortable for most standard headstone slabs. On black granite, a single pass with the standard lens typically achieves 0.3–0.5mm depth with a high-contrast white mark. For deeper engraving, multiple passes are needed. If you’re primarily doing lettering and portraits, the single-pass contrast is usually sufficient, and you can follow with light sandblasting if needed. We can send you sample parameters for granite if that helps.
