Bridge Cutting Machine for Natural Stone & Concrete

The PLC (Programmable Logic Controller) control system represents the technological core of our bridge cutting machine, offering significant benefits for professional stone fabrication:

Complete parameter customization: Operators can precisely set the number of cuts, processing thickness, cutting depth, and feed speed according to specific project requirements;

Unattended operation: Once parameters are programmed, the machine operates autonomously until all processing is complete, optimizing workforce allocation;

Consistent precision: The system maintains exact cutting specifications across multiple pieces, ensuring dimensional uniformity in batch production;

User-friendly interface: The intuitive human-machine interaction panel makes complex cutting operations accessible to operators of various skill levels;

Error reduction: Automated control minimizes human error in critical cutting operations, reducing material waste and rework.

This intelligent control system transforms stone fabrication from a labor-intensive process to a precision-controlled operation, significantly enhancing productivity while maintaining exceptional quality standards.

The infrared laser positioning device is a precision alignment system that significantly enhances cutting accuracy and quality in our bridge cutting machine. This advanced technology works through the following process:

Accurate line marking: The infrared device projects a visible alignment line onto the stone surface that precisely indicates where the cutting blade will make contact;

Perfect blade alignment: This visual guidance system ensures the diamond blade is perfectly positioned before cutting begins, eliminating misalignment issues;

Real-time reference: During cutting operations, the system provides continuous visual feedback to verify cutting accuracy;

Error prevention: By confirming proper alignment before material processing begins, the system prevents costly mistakes on valuable stone materials;

Consistent results: The positioning system maintains identical alignment across multiple cuts, essential for projects requiring matched pieces.

This infrared laser technology works in conjunction with the PLC control system and encoder-based division mechanism to deliver exceptional dimensional accuracy. For stone fabricators, this translates to higher-quality finished products, reduced material waste, and increased customer satisfaction through precision craftsmanship.

The encoder-based slab dividing system is a precision technology that ensures exceptional dimensional accuracy when cutting stone materials into multiple pieces. This advanced system functions through the following mechanisms:

Ultra-high precision rotary encoder: This device tracks the exact position of the cutting blade with microscopic accuracy throughout the cutting process;

Digital position monitoring: The system continuously measures and verifies the cutting head's location, ensuring precise dimensional control;

Automatic compensation: Real-time adjustments correct for any mechanical variations or movement deviations during operation;

Programmed division parameters: Operators can set exact dimensional specifications for multiple cuts, which the system then executes with perfect consistency;

Enhanced stability: The encoder feedback loop improves overall machine stability by preventing drift or accumulating errors during extended operations.

This sophisticated division system is particularly valuable for applications requiring multiple identical pieces, such as tombstone production, dimensional panels, or matched architectural elements. By maintaining precise dimensional control throughout the cutting process, the encoder system ensures that each piece meets exact specifications, reducing material waste and virtually eliminating the need for manual adjustments or corrections.

This bridge cutting machine is specifically designed for medium to thick stone processing with a maximum cutting height of 680mm when equipped with a 1600mm saw blade. This height capacity makes it ideal for:

• Monument and tombstone fabrication, where substantial thickness is often required;
• Dimensional stone slab production with consistent thickness control;
• Curbstone and architectural element manufacturing;
• Standard construction blocks and panels.

The robust hydraulic lifting system provides precise height control throughout this range, while the PLC control system allows operators to set exact cutting depths for each project. This specialized height capacity positions the machine perfectly for professional stone fabricators focusing on memorial, architectural, and construction applications requiring substantial material thickness.

The DINOSAW Bridge Cutting Machine is designed with operator-friendly features that make it accessible even to those with limited experience in CNC equipment. The intuitive touchscreen interface uses visual programming methods with a built-in template library for common cutting operations.

New operators typically require just 2-3 days of training to become proficient with basic functions. For more complex operations, our machines include comprehensive on-screen guidance and context-sensitive help.

The control system also features safety protocols that prevent operator errors that could damage materials or equipment. No special programming knowledge or CNC background is required, as our patented operation system focuses on practical stone fabrication workflows rather than abstract programming concepts.

We provide detailed training during installation and offer ongoing support through our technical team, ensuring your operators can maximize the machine's capabilities regardless of their prior experience level.

The choice between this PLC Bridge Cutting Machine and a multi-axis CNC system depends on your specific production requirements:

Choose this PLC Bridge Cutting Machine when:

• Your production primarily involves straight cuts and 45-degree bevels on thick materials;
• You process medium-height materials (up to 680mm with 1600mm blade);
• You manufacture standardized products like dimensional slabs, tombstones, and curbstones;
• You need high-volume production with simplified operation;
• Operational speed and cost-efficiency are priorities;
• You focus on professional monument and thick slab production.

Choose a 4-axis or 5-axis CNC Bridge Saw when:

• You need to produce kitchen countertops, bathroom vanities, or sinks with cutouts;
• Your projects require curved cuts, profiling, or complex shapes;
• You need to process thinner materials with intricate details;
• You need multi-directional cutting capabilities;
• Your production requires detailed 3D work;
• You need maximum flexibility for diverse custom projects.

Many fabrication shops benefit from having both types of machines, using this specialized PLC model for high-volume tombstone and thick slab cutting, and the CNC system for custom work requiring additional axes of movement.

The DINOSAW Bridge Cutting Machine supports multiple blade diameter configurations to suit different cutting requirements:

• QSZQ-1200: Maximum blade diameter of 1200mm;
• QSZQ-1400: Maximum blade diameter of 1400mm;
• QSZQ-1600: Maximum blade diameter of 1600mm.

Larger blade diameters enable deeper cutting capacity. With the 1600mm blade, the machine achieves its maximum cutting height of 680mm, making it ideal for thick stone applications such as monument fabrication and large dimensional blocks.

The power requirements vary by model configuration:

• QSZQ-1200: Main motor 22kW, Total power 27kW;
• QSZQ-1400: Main motor 30kW, Total power 37kW;
• QSZQ-1600: Main motor 30kW, Total power 37kW.

The main motor drives the cutting blade, while the total power includes all auxiliary systems such as the hydraulic lifting mechanism, table rotation, and cooling systems. We recommend consulting with our technical team to ensure your facility's electrical infrastructure can support your chosen model.

The DINOSAW Bridge Cutting Machine offers flexible table rotation configurations:

• 90° rotation: Standard configuration for most cutting operations;
• 360° rotation: Full rotation capability for complex multi-angle cutting.

The table dimensions are 3000mm × 2000mm across all models, providing ample workspace for large stone slabs. The rotation system is precision-controlled and integrated with the PLC system for automated positioning during batch operations.

Three systems work together: 22–30 kW main motors with 850–950 mm hydraulic lifting stroke for the cutting power, hydraulic lifting with solid guide columns for smooth feed, and the oil-immersed roller and linear guide transmission that keeps movement smooth under load. The encoder-based division with infrared laser positioning calibration then keeps each successive cut aligned to the blank reference, which is what preserves flatness on thick sections.

They serve different production tasks. A countertop bridge saw optimizes slab cutting for kitchens and vanities — moderate thickness, high frequency, nested sheet layouts. The QSZQ is a heavy-duty bridge cutter for thick stone: 680 mm cutting height, deep-cut structure and PLC unattended cycles for monument blanks, curb stones and architectural components. If your work is thick blanks and construction stone rather than countertops, the QSZQ is the right class of machine.

Yes — that is the point of the PLC set-and-walk-away control. The operator enters cutting dimensions and cycle parameters once; the machine then completes repeated cuts automatically, including table rotation between faces. One operator can supervise several tasks while long monument or thick-slab cycles run, which is also where the roughly 15% productivity gain over attended conventional cutting comes from.
