Stone Block Cutting Machine for Granite, Marble, and Limestone Blocks

This is a bridge-type stone block cutting machine.

What that means in practice

• A full bridge spans over the stone block

• Cutting force is supported on both sides

• The block stays fixed while the machine cuts

Compared with single-column or compact block cutters, a bridge-type structure is built for larger blocks, heavier loads, and long continuous cutting.

What to confirm before deciding
Confirm whether your current block cutter struggles with block size, stability, or long cutting cycles.

The difference comes mainly from structure and capacity, not small feature details.

Compared with other common block cutters

• Versus single-column block cutters: more stable on large blocks

• Versus compact or trolley-type machines: much larger cutting range

• Versus horizontal blade block cutters: better suited for tall and wide blocks

Bridge-type machines are chosen when block size and long-term stability matter more than compact footprint.

What to confirm before deciding
Look at the type of block cutter you are currently using and where its limits appear in daily production.

A bridge-type structure allows much larger cutting dimensions than compact block cutting machines.

What this means for your production

• You can cut wider and taller stone blocks

• Heavy blocks can be processed without frequent repositioning

• Long straight cuts remain stable across the full block width

The open bridge span is the key reason this type of machine is used for large-format stone blocks.

What to confirm before deciding
Check your maximum block width, height, and weight against the machine’s cutting dimensions.

Check length, width and height together against the selected model. The catalogue lists maximum cutting sizes of 4000 × 2200 × 950 mm for LMDQ-2200, 3700 × 2200 × 1100 mm for LMDQ-2500, 3500 × 2200 × 1300 mm for LMDQ-2800 and 3500 × 2200 × 1350 mm for LMDQ-3000.

Illustrative size check: A block measuring 3600 × 2000 × 1200 mm exceeds the height of the first two models and the length of the last two. None of the four listed envelopes covers that complete block, even though the larger blade classes meet its height. Evaluate block preparation or a confirmed extended configuration before selecting a model.

Use the required cutting orientation, actual support and loading arrangement with this check. Confirm the permitted block weight and handling capacity separately; the machine's approximate weight in the table is not its workpiece load rating.

Factories choose bridge-type block cutters because they are more stable, handle larger blocks, and support higher-throughput block cutting.

What you gain in real production

• Fewer interruptions during long cuts

• Less block handling and repositioning

• A more reliable front-end cutting stage for slab production

This makes bridge-type machines suitable when block cutting is a core production step, not an occasional task.

What to confirm before deciding
Confirm whether your current block cutting stage limits overall factory output.

The LMDQ block cutter and a frame gangsaw can both be evaluated for block-to-slab production. The useful comparison is the cutting system and the slab program each machine supports.

How the systems differ

• LMDQ circular-blade block cutter: Select the single- or multi-blade setup, blade diameters and cutting envelope around the block size and repeated slab dimensions.
• Frame gangsaw: Uses frame-mounted blades for slab sawing. Compare the material, slab dimensions, kerf, accepted recovery and downstream finishing required by the proposed setup.

How they fit your production line

An LMDQ configured for block sizing may prepare material for a later cutting stage. When configured for multi-blade slab cutting, it performs the slab-cutting task itself. A frame saw can therefore be an alternative for a slab program or part of a different line arrangement; the sequence depends on the job.

What to confirm before deciding

Compare the same stone, block dimensions, slab thickness and finished dimensions. Include setup, loading, unloading, tool consumption, trimming and subsequent finishing when assessing output and recovery.

Yes. This bridge-type block cutter can be configured with a single blade or multiple blades, depending on your production needs.

How different blade setups are used

• Single-blade setup

  • Used for flexible block sizing

  • Suitable when block dimensions vary

  • Easier setup and adjustment

• Multi-blade setup

  • Used for higher-throughput block cutting

  • Allows multiple parallel cuts in one pass

  • Suitable for standardized block sizes and stable production runs

Because of the bridge-type structure, the machine can support heavier blade loads and maintain stability even with multiple blades installed.

What to confirm before deciding
Confirm whether your blocks are standardized enough to benefit from multi-blade cutting, or whether you need the flexibility of single-blade operation.

This machine is best suited for factories where block cutting is a continuous, high-load operation.

You are a good fit if

• You process large natural stone blocks daily

• Block cutting is a bottleneck in your production line

• You need stable cutting on heavy blocks

It is commonly used in medium-to-large stone factories that handle significant block volumes.

What to confirm before deciding
Assess whether block cutting is a core operation or an occasional task in your factory.

A bridge-type block cutter requires proper planning for space, power, and material handling.

Key points to plan for

• Sufficient floor space for large blocks

• Stable power supply for heavy-duty cutting

• Lifting equipment for block loading

Daily operation focuses on straight cutting and monitoring the cutting process rather than complex setup.

What to confirm before deciding
Confirm available space, power capacity, and block handling equipment in your workshop.

This machine may not be the right choice if your block cutting needs are limited or highly specialized.

It may not fit your needs if

• You only cut small blocks occasionally

• Your required slab dimensions, material or recovery target are better served by a different sawing route.

• An existing or more compact machine already meets the block size, cutting program and production volume you need.

In these cases, other block cutting machines may be more cost-effective.

What to confirm before deciding
Be clear about your actual block cutting workload and where this machine fits in your production flow.

The machine mounts a set of blades at fixed spacing on the spindle; each pass cuts one slab per blade gap, so a nine-blade set slices up to eight slabs per pass. The combination is selected per slab thickness program: for 20 mm tiles the set uses closely spaced smaller blades (e.g. Φ2200+Φ2000+Φ1800+… down to Φ600), while thicker programs use fewer, larger blades. DINOSAW recommends the blade combination from your target slab thickness and block dimensions at configuration.

Check the model-specific blade count as well as diameter. LMDQ-2200 and LMDQ-2500 are listed with up to 9 blades, while LMDQ-2800 and LMDQ-3000 show 1(5) in the catalogue. Specify the actual blade combination in the quotation rather than assuming the largest diameter uses the most blades. Match the combination's working depths and spacing to the slab program.

No — blade count and slab count are related but not identical. A nine-blade set creates eight spaces between blades, so a standard nine-blade configuration produces up to eight slab sections per pass. The actual arrangement depends on the slab thickness program and the blade combination, which DINOSAW configures with you before delivery.

Choose multi-blade when your slab thickness is standardized and volume is the target: the LMDQ slices several slabs per pass at up to 120 m²/h with ±0.2 mm consistency across the stack. Choose the QSDP single-blade cutter when block sizes vary, products change between slabs, kerbs and tombstone blanks, or the work is trimming-oriented. Many factories run both — single-blade for flexible jobs, multi-blade for the volume program.

A multi-blade LMDQ can be evaluated for repeated straight cutting of marble blocks into the slab dimensions supported by its configuration. Start with the material condition, usable block size, target thickness and required finished format.

When comparing machines for marble block cutting, measure kerf and trimming loss, accepted slab recovery, complete-cycle output, tool consumption and subsequent calibration or polishing on the same job. Include the proposed frame-saw or multi-wire route where relevant. The best choice depends on that production comparison and your order mix.
