Stone Slab Cutting Machines

Ledrobit Stone Slab Cutting Machines is developed for stone processing companies that need to convert large blocks into multiple slabs efficiently. The machine uses a bridge-type gantry structure and supports 8–26 circular saw blades, allowing different cutting configurations according to block dimensions and required slab output.

The equipment is available in multiple standard configurations as well as customized sizes. With CE-oriented manufacturing, customizable power supply, and OEM/ODM support, Ledrobit provides a flexible solution for stone machinery distributors, importers, and overseas brands.

Designed for Large Stone Blocks

The Stone Slab Cutting Machines is intended for processing large-format granite, marble, and other natural or engineered stone blocks. Its working dimensions can be adjusted according to the size of the material and the layout of the customer's production facility.

The standard bridge beam is available in lengths of 6800, 8500, and 10000 mm, while customized crossbeam configurations can reach 15000 mm. Side beam lengths can also be selected according to the required longitudinal travel and installation space.

This makes the machine suitable for factories handling different block sizes rather than being restricted to a single fixed production specification.

Flexible Blade Configurations

Cutting capacity is closely related to the number and arrangement of saw blades. The LD-2500 supports 8 to 26 blades, with tower or combined mounting configurations available.

The blade arrangement can be selected according to the required slab thickness, block size, and production method. The equipment can also be configured for single-, double-, or quadruple-block processing.

For manufacturers producing large quantities of slabs, multi-blade cutting allows several slabs to be produced during one cutting cycle. This can reduce repeated loading and cutting operations and help improve production efficiency.

The maximum compatible saw blade diameter is Φ1750 mm, with a spindle diameter of Φ120–Φ150 mm and blade mounting shaft length of 430–1100 mm.

Consistent Slab Thickness

For stone processors, cutting accuracy affects not only the appearance of finished slabs but also subsequent polishing, grinding, edge processing, and installation.

The Stone Slab Cutting Machines uses a four-column hydraulic lifting system with proportional control. Its specified positioning precision reaches ±0.01 mm. Hydraulic locking helps maintain stability during the cutting process.

This configuration is intended to keep the blade position consistent during vertical movement and help produce slabs with uniform thickness and flatness.

Smooth Movement During Cutting

Long travel distances require stable movement from the cutting head and gantry system. The LD-2500 uses imported HGH55HA/HGH65HA linear guide rails together with precision helical gear transmission.

The cross travel range can be configured from 3500 to 7500 mm, while longitudinal travel ranges from 2400 to 8000 mm. These options allow the machine to be matched to different block dimensions and production layouts.

The guide system is designed to provide smooth movement and reduce backlash during repeated cutting operations, which is particularly important for continuous production.

Programmable Cutting Control

Operators need to adjust cutting parameters when processing different types, sizes, or thicknesses of stone. The LD-2500 uses a PLC control system with recipe setting and wireless remote control.

Cutting programs can be configured according to the production requirements, including cutting methods, number of cuts, slab thickness, and blade cutting depth.

Saved programs can be recalled for repeated production, helping reduce repeated manual parameter input when the same type of slab needs to be processed in batches.

Energy and Water Requirements

Optional Permanent-Magnet Motor

Operating costs are an important consideration when comparing industrial stone cutting equipment. The LD-2500 is available with a permanent-magnet motor as an optional configuration, with a specified energy-saving range of approximately 10%–15% compared with the standard configuration.

The main motor power can be selected from 45 kW, 75 kW, or 110 kW depending on the machine configuration and cutting requirements.

Water-Cooled Cutting System

Water-cooled cutting is used to control blade temperature during operation. The specified water consumption is approximately 14–30 m³/h.

For factories running the equipment for extended periods, these parameters should be considered together with local electricity costs, water availability, block characteristics, blade selection, and production volume when calculating total operating costs.

Large-Diameter Blade Capacity

The LD-2500 supports saw blades up to Φ1750 mm in diameter, providing the cutting depth required for large stone blocks.

The spindle diameter is available from Φ120 to Φ150 mm, while the blade mounting shaft length can be configured from 430 to 1100 mm.

Continuous water cooling helps control heat generated during cutting, while also helping reduce dust in the working environment.

Configuration for Different Factories

Custom Beam Sizes

A stone processing plant may have different block dimensions, workshop sizes, electrical standards, and production targets. For this reason, the LD-2500 is not limited to one fixed machine configuration.

Standard bridge beam lengths include 6800, 8500, and 10000 mm, while customized crossbeam lengths can range from 6500 to 15000 mm. Side beam lengths can be customized from 4500 to 12000 mm.

Customized Machine Parameters

Blade quantity, motor power, travel range, frame dimensions, and destination-specific power supply can also be configured according to the project requirements.

This approach allows buyers to specify the equipment around their existing workshop and production process instead of adapting the entire facility to an oversized or undersized machine.

Suitable Materials

The machine is designed for processing:

• Granite blocks
• Marble blocks
• Engineered stone blocks
• Other compatible natural stone blocks

It is particularly suited to applications where large blocks need to be divided into multiple slabs with controlled thickness and repeatable cutting performance.
