Product Overview
The Superstar CX-1325 Stone CNC (manufactured by Jinan Jinshengxing Machinery Manufacture Co., Ltd.) is specifically engineered for the memorial and architectural stone industries. While standard wood CNC routers quickly fail under the immense vibration and abrasive dust generated by stone cutting, the CX-1325 thrives.
Constructed on a heavy-duty, low-center-of-gravity steel bed, it can bear the massive weight of thick granite slabs and tombstones without micro-deformation. To ensure continuous operation, the machine utilizes a specialized dual-nozzle water cooling system that floods the cutting area, extending the life of diamond tooling and preventing the stone from cracking due to thermal shock.
Core Advantages
Waterproof & Dustproof "Bellows" System: All square guide rails and helical rack gears on the X and Y axes are fully enclosed in accordion-style protective covers. This completely seals out abrasive stone dust and muddy water, drastically extending the machine's lifespan.
Stainless Steel Water Circulation Tank: The aluminum T-slot worktable is surrounded by a corrosion-resistant stainless steel trough. This system captures, filters, and recirculates the cooling water, keeping your shop floor dry and reducing water consumption.
High-Torque Water-Cooled Spindle: Equipped with a standard 5.5KW (optional 7.5KW) high-frequency water-cooled spindle. It provides the sustained low-speed torque required to grind through hard granite and bluestone without stalling.
Ergonomic Loading Wheels: Heavy-duty roller wheels are integrated into the front of the machine bed, allowing operators to easily slide heavy stone slabs into place without the need for a forklift or risking physical injury.

Detailed Component Analysis
Unlike standard aluminum-profile machines, the CX-1325 features a thick-walled square steel tube frame that has been thermally tempered to relieve stress. This immense mass absorbs tool chatter, guaranteeing perfectly smooth 3D relief backgrounds and crisp V-carved lettering.
A high-pressure water pump shoots coolant directly onto the diamond bit from two opposing angles. This instantly flushes away the "stone mud" before it can re-cut, preserving the sharpness of the tool and preventing burn marks on the stone.
Riding on 25mm industrial square guide rails, the heavy gantry moves smoothly and accurately, ensuring exact depth control (±0.05mm) even during aggressive multi-pass plunge cuts.
Applicable Industries & Materials
Memorial Industry: Deep V-carving text, intricate 3D portraits, and floral motifs on granite and marble tombstones.
Architectural Stonework: Milling fireplace mantels, exterior wall cladding, and routing Roman columns (requires optional rotary axis).
Countertop Fabrication: Cutting sink holes and profiling edges on Quartz, Sandstone, and artificial stone slabs.
Compatible Materials: Granite, Marble, Bluestone, Sandstone, Quartz, Artificial Stone, Jade, and Glass.
Why Choose Superstar CNC?
Purpose-Built for Stone: We do not simply adapt wood routers for stone processing. The CX-1325 is designed from the ground up with a low center of gravity and extreme waterproofing explicitly for wet, abrasive environments.
Tooling Expertise: Stone requires highly specific diamond-sintered or brazed bits. We leverage our factory experience to recommend and supply the exact tooling formulas required for your specific stone types, saving you expensive trial and error.
Frequently Asked Questions
Q: Can this machine cut entirely through a 3cm thick granite slab in one pass?
A: No. To protect the diamond bit and the machine spindle, stone requires "step-down" cutting (typically 2-4mm per pass, depending on the stone's hardness). The CNC software automates these multi-pass depths easily.
Q: How do I program the machine?
A: You can design your artwork (text, 3D reliefs, or CAD vectors) in standard software like ArtCAM or Vectric Aspire. You then export the G-code to the machine's NcStudio or DSP controller via USB.
Q: Does the machine require a dedicated water line?
A: No, it features a self-contained stainless steel water tank and recirculation pump. You simply fill the tank, and the system filters and reuses the water during the cutting process.
