CNC Stone Polishing Machine with Automatic Tool Change for Tombstone Finishing

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.

Continuous polishing production lines are optimized for high-volume standardized thin slab stone production, mainly used for countertops and floor tiles. Their advantage lies in consistency of large quantities of similar materials in mass production environments.

However, our CNC ATC Grinding & Polishing Machine is designed for customized, special stone processing, where versatility and adaptability are core strengths. It has significant advantages in monument manufacturing, irregular processing, and thick material handling:

1. Can flexibly handle different thicknesses (up to 1000mm), which continuous production lines cannot achieve
2. Achieves precision processing of irregular workpieces through visual recognition
3. Can process multiple different workpieces simultaneously
4. Complete full-process processing from coarse grinding to fine polishing in a single setup
5. Adapt to special materials and custom projects

For workshops processing monuments, custom architectural components, or special stone materials, our equipment provides versatility and precision that continuous polishing production lines cannot match.

Three steps, no measuring. First, place the tombstones or slabs within the camera work area — no alignment fixtures needed. Second, the industrial camera photographs the work zone and the image appears on the control screen; the operator drags the polishing outline onto the real image and sets parameters visually. Third, press start: the machine locates each workpiece from the image and runs the cycle. Layout marking, tape measures and manual edge alignment disappear from the workflow — which is why a new operator learns the full process in about 10 minutes and production no longer depends on a master craftsman's availability.

Finishing time drops by about 65% against manual tool-change workflows, and shift output rises by roughly 30%. In a manual workflow, the operator stops the machine, swaps abrasives by hand and re-verifies position at every stage change — for a tombstone running rough grind, fine grind and polish, that is two interruptions per piece. The DP-01's magazine holds all eight tool positions and switches automatically, so the cycle runs start to finish without stopping: the reference production figure is 6–12 granite tombstones per shift at repeatable 95 GU gloss, with thickness held within 0.5 mm across the batch. Note the two numbers measure different things — 65% less finishing time per workflow, 30% more output across the shift.

When your products vary in shape and size. A continuous line (TBMJ/DBMJ) is unbeatable for standardized rectangular big slabs — but it is built around slabs moving straight through heads on a belt. The DP-01 wins on tombstones, shaped countertops, irregular polygons and mixed-size batches: the vision system locates each piece individually, so different products share one setup. These are parallel choices, not a high-low pairing: standardized slab volume points to a line; high-mix shaped and memorial work points to the DP-01. Many factories run both — the line for slabs, the DP-01 for shaped and memorial work.

Choose by product geometry. The QDMJ bridge single-head polisher serves standard slabs, countertops and monuments across flexible widths — one setup at a time, economical, moderate volume. Choose the DP-01 when shapes and mixed sizes define the work: tombstones with irregular outlines, polygons and rounds, batches where several dimensions share one run — the camera positioning and 8-station automatic tool change remove the setup and tool-swap labor that the QDMJ still needs manually. A practical split many factories use: the QDMJ for rectangular slab and countertop work, the DP-01 for shaped memorial and high-mix batches.
