Diamond Wire Saw Machine

High cutting efficiency, intelligent tension control, and flexible operation for granite, marble and sandstone quarries.

Extracting high-quality natural-stone blocks requires more than simply cutting rock. Quarry operators need to balance cutting efficiency, block recovery, wire consumption, energy use and operational safety.

The STONEX Diamond Wire Saw Machine is designed to provide a controlled and efficient solution for quarrying granite, marble, sandstone and other natural stones. With models ranging from the compact HSJ-22G to the high-power HSJ-83G, STONEX offers different configurations for quarry operations with different cutting requirements.

Diamond wire sawing uses a continuous diamond-impregnated wire to cut through natural stone. Compared with conventional mechanical breaking methods, it allows quarry operators to make deep, narrow and controlled cuts with relatively low vibration.

This makes diamond wire sawing particularly useful for dimension-stone quarrying, where the objective is not simply to remove rock but to produce commercially valuable blocks with controlled dimensions and minimum unnecessary waste.

Typical applications include:

• Granite block extraction
• Marble quarrying
• Sandstone quarrying
• Deep vertical cutting
• Horizontal or bottom cutting
• Block separation
• Irregular block recovery
• Quarry block squaring and preparation

STONEX offers four power configurations in the supplied technical range:

This range allows buyers to select a machine according to required cutting area, quarry scale, stone type and production target.

The power head provides 0–360° rotation, while the maximum power-head travel reaches 450 mm on the larger models. Maximum cutting distance ranges from 1,200 mm to 1,950 mm, depending on the model.

The main flywheel provides a maximum linear wire speed of 35–40 m/s, depending on the model, while feed speed can be adjusted from low-speed precision cutting to faster production cutting.

This flexibility is important because optimal cutting parameters depend on:

• Stone hardness
• Stone abrasiveness
• Diamond wire specification
• Cutting direction
• Wire condition
• Required cutting efficiency
Rather than using one fixed setting for every material, operators can select appropriate wire and machine parameters for the actual quarry conditions.

The diamond wire is one of the most important consumables in the entire quarrying system.

The supplied STONEX specifications include different diamond-wire configurations for granite and marble quarrying.

For granite quarrying, the technical sheet lists:

• W10: Ø11.5 mm bead diameter, 40 or 37 beads/m, sintered bead, rubber coating
• W15: Ø12.0 mm bead diameter, 40 beads/m, sintered bead, rubber or spring coating
For marble quarrying:
• W8: Ø11.5 mm bead diameter, 40 or 37 beads/m, sintered bead, rubber/spring coating
• W9: Ø11.0 mm bead diameter, 40 or 28 beads/m, sintered bead, rubber or spring coating
The appropriate wire should be selected according to the material and actual quarry conditions.

The supplied data shows how cutting performance changes with stone characteristics.
For granite quarrying and raw blocks:

Actual results will vary according to geological conditions, wire specification, machine settings and operator practice.

This is why a professional quarrying solution should consider the machine and diamond wire as one cutting system, rather than evaluating the saw alone.

STONEX diamond wire saws are designed for demanding quarry environments.

The machine can be configured for different cutting positions, while the power head provides 0–360° rotation to support flexible cutting arrangements.

The structure is designed to provide stable operation while allowing convenient machine positioning and maintenance.

The wire-guide components use corrosion-resistant treatment, and standard components are available in stainless steel to improve durability in wet quarry environments.

Flexible Machine Selection

Four power configurations from 22 kW to 83 kW accommodate different production requirements.

High Cutting Efficiency

The larger models provide cutting efficiencies of up to 20 m²/h under suitable conditions.

Large Cutting Capability

Maximum cutting area reaches 200 m² on the HSJ-83G.

Adjustable Wire Speed

Maximum main flywheel linear speed reaches 40 m/s on the larger models.

Flexible Power-Head Movement

The power head provides 0–360° rotation.

Suitable for Multiple Stones

The machines can be used for granite, marble, sandstone and other dimension stones with appropriate diamond wire selection.

A diamond wire saw is particularly attractive when your quarry prioritizes:
• High-value commercial blocks
• Controlled block dimensions
• Reduced unnecessary material loss
• Deep or long cuts
• Flexible cutting directions
• Lower-impact separation compared with blasting
For large-scale production, it can also be combined with large-diameter quarry saws, drilling equipment, hydraulic splitting systems and lifting equipment to create a more efficient block-extraction workflow.
