CNC Stone Polishing Machine with Automatic Tool Change for Tombstone Finishing

The DINOSAW CNC ATC Grinding & Polishing Machine offers significant advantages over manual polishing and single-head automatic polishers for monument and irregular stone processing.

Compared to hand polishing, this equipment achieves fully automated operation, eliminating physical labor and operator fatigue while ensuring better consistency.

Unlike single-head automatic polishers that require multiple setups to complete different grinding stages, our multi-tool system automatically transitions from coarse grinding to fine polishing in a single operation. This reduces processing time by up to 50% and eliminates handling damage between stages. The integrated visual recognition system is a unique feature of our equipment, capable of precisely handling irregular and complex shapes that single-head equipment cannot effectively address.

Our CNC ATC Grinding & Polishing Machine's visual recognition system uses high-resolution digital cameras installed above the work area to capture images of stones of various shapes and sizes.

When stone workpieces are placed on the machine table, the camera captures photos that are processed by our proprietary image recognition software. The system automatically identifies the contours of irregular shapes, creating a digital profile of the workpiece. Operators can then select specific processing areas through the touchscreen interface, or choose the entire surface with one click.

The software analyzes shape characteristics and automatically generates optimal grinding paths along the material contours. This eliminates inefficient processing outside stone edges, ensuring complete coverage of complex shapes. The system adjusts grinding pressure and tool position based on specific geometric shapes, maintaining consistent quality even on curved or angular surfaces that traditional equipment struggles with.

The DINOSAW CNC ATC Grinding & Polishing Machine can process various materials beyond traditional stone.

In the natural stone category, it can handle various types including Black Galaxy, Indian Red, Blue Pearl granite, sandstone, basalt, travertine, slate, quartzite, marble (Carrara, Calacatta, Spanish Beige), jade, limestone, serpentine, and soapstone. Each stone benefits from precise pressure control and uniform material removal, adapting to their different density characteristics.

In addition to natural stone, with appropriate grinding media changes, this equipment can also effectively process engineered stone, ceramic, concrete precast components, glass, and various composite materials. The system can even be adapted for industrial applications such as metal plate surface rust removal and finishing of specialized industrial components.

This material diversity stems from the combination of intelligent pressure control, adjustable processing parameters, and automatic tool change capabilities. The visual recognition system adapts to any material surface, allowing customization of dedicated processing programs based on each material's unique hardness and texture requirements.

The DINOSAW CNC ATC Grinding & Polishing Machine specializes in stone processing fields requiring high precision and surface flatness.

In monument processing, it can handle various specifications from standard flat tombstones to large family monuments up to 1000mm thick. This equipment excels in surface treatment of flat memorial stones, where surface consistency directly affects final aesthetic quality.

This equipment is suitable for various flat architectural components, including stair treads, thresholds, window sills, floor tiles, and wall panels. It can precisely process rectangular and irregular decorative panels, custom stone furniture components, and flat architectural parts requiring consistent surface treatment. The visual recognition system ensures complete edge processing of non-rectangular workpieces.

In special surface processing, the CNC system creates precise and uniform surface effects on high-value decorative stone, flat statue bases, memorial benches, flat paving stones, and custom-shaped monuments. Its flat grinding capability makes it ideal for large-scale flooring projects, countertops, and memorial wall installation projects.

Yes, one of the advantages of the DINOSAW CNC ATC Grinding & Polishing Machine is the ability to process multiple different workpieces simultaneously in a single setup, significantly improving production efficiency.

The equipment has a large processing area of 3000×2800×1000mm, accommodating various shapes, sizes, and thicknesses of stone workpieces in a single batch. The visual recognition system independently identifies each workpiece on the table, and operators can set different processing parameters for each piece.

When processing begins, the system automatically adjusts grinding height, pressure, and path planning for each stone workpiece. The equipment automatically switches between different workpieces, executing corresponding grinding processes and polishing stages according to each piece's specific requirements. This eliminates the need for individual setup and machine time occupation for each workpiece.

This batch processing capability is extremely valuable for monument workshops handling diverse orders, allowing simultaneous completion of different customer projects while ensuring consistent quality across all workpieces.

The DINOSAW CNC ATC Grinding & Polishing Machine and continuous polishing production lines (such as DINOSAW's automatic slab polishing machine) serve different purposes and market segments.
