RUSHENG MACHINERY 18-Blade Bridge-Type Combined Stone Cutting Machine

This equipment is an 18-blade bridge-type combined stone cutting machine manufactured by RUSHENG MACHINERY. As a large-scale, high-throughput cutting system in the stone processing sector, it is purpose-built for batch slabbing of bulk stone blocks (e.g., granite, marble) and ranks as a high-efficiency core model within the industry.

I. Core Configuration & Technical Specifications 

• Saw Blade Assembly

1. Furnished with 18 diamond-tipped saw blades , with a typical blade diameter range of Φ2200–Φ2800mm (to accommodate varying block dimensions) and a blade thickness of 6.5–8.0mm;
2. Supports synchronous/asynchronous cutting operations, enabling single-pass conversion of large blocks into 17–18 standard slabs (e.g., 18mm-thick granite panels). Its cutting efficiency exceeds 15 times that of conventional single-blade systems.

•  Power & Drive System

1. Main motor power: 55–75kW (engineered to handle high-load demands of multi-blade setups), with a total installed power of 70–90kW;
2. Drive mechanism: Utilizes a servo motor + high-precision lead screw/hydraulic system, delivering crossbeam positioning accuracy of ≤0.1mm to ensure consistent cutting performance across all blades.

• Mechanical Structure & Dimensions

1. The frame integrates a heavy-duty steel structure + one-piece alloy steel crossbeam, with an overall machine weight of 15–20 tonnes to maintain stability during high-speed operation;
2. Equipment dimensions (L×W×H): Approx. 10m×5m×4m, requiring a dedicated large-scale stone processing workshop or open-air processing yard.

• Control System

1. Equipped with a PLC control system + touchscreen human-machine interface (HMI), supporting preset cutting parameters (e.g., block size, slab thickness) for user-friendly operation, even for novice personnel;
2. Features infrared positioning + fault self-diagnosis functionality: Cutting paths are automatically corrected, and alerts are triggered upon anomaly detection to facilitate streamlined maintenance.

II. Core Functions & Advantages

• Ultra-High Throughput

1. A single unit can process 80–120 cubic meters of stone blocks daily (for granite as a reference), equivalent to the output of 10–15 single-blade units, significantly reducing labor costs;
2. Compatible with 3–5 cubic meter large blocks, allowing direct cutting without pre-splitting, thereby eliminating intermediate processing steps.

• High Precision & Low Material Waste

1. Cutting tolerance: ≤0.5mm/m, ensuring high slab flatness and reducing material waste in subsequent polishing processes by 30%;
2. Saw blades employ automatic feed rate adjustment (calibrated to stone hardness), extending blade service life (a single blade set can process approximately 5,000 cubic meters of blocks).

• Operational & Maintenance Convenience

1. ​​​​Blocks can be cut directly on the ground (no dedicated workbench required), minimizing space and equipment costs;
2. Key components (e.g., lead screws, guide rails) incorporate a sealed dust-proof design, extending maintenance intervals to once every 3 months and reducing unplanned downtime.

III. Application Scenarios

• Primarily deployed in medium-to-large stone processing facilities and mine-associated processing workshops for producing granite/marble slabs for architectural cladding and decoration;
• Also suitable for cutting artificial stone and quartz stone, serving as a front-end core device in the stone industry chain.

IV. Market Positioning & Competitor Benchmarking

• Classified as a high-end heavy-duty stone cutting machine, offering customizable blade configurations (blade count can be adjusted to suit specific processing requirements);
• Compared to comparable multi-blade models, it delivers a 12% higher throughput and superior overall processing efficiency.
