Products Description
Granite Multi-wire Saw Machine | STONEX HLMW-U
Stable Structure. Balanced Tension. High-Efficiency Stone Slab Cutting.
The STONEX HLMW-U Multi-Wire Saw Machine is engineered for efficient slab production from granite, marble, quartzite and other natural stone blocks. Its two-column, symmetrical triangular wire-path structure combines rigid mechanical support, balanced wire tension and intelligent CNC control to deliver stable cutting, consistent slab thickness and high production efficiency.
With 42, 56, 72 and 86-wire configurations, the HLMW-U series can produce up to 41, 55, 71 and 85 slabs respectively in one cutting cycle, depending on the selected slab thickness and wire configuration.
Symmetrical Triangular Wire-Path
Balanced Structure. Stable Cutting. Consistent Slabs.
The HLMW-U adopts a two-column symmetrical structure with a triangular wire-path design. The left and right wheel systems are arranged symmetrically around the working area, helping distribute mechanical forces and wire tension more evenly.
Combined with a rigid column-and-beam structure, this design helps reduce vibration and maintain stable diamond-wire positioning throughout the cutting process.
The result:
• More stable multi-wire cutting
• Better wire alignment
• More consistent slab thickness
• Reduced vibration
• Improved surface quality
Stable & Balanced Wire Tension
Equalized Tension Across Every Diamond Wire
Multi-wire cutting requires every diamond wire to operate under stable and balanced tension. The HLMW-U uses a hydraulic tensioning and balance system to maintain controlled tension across the wire group.
With individual wire tension of 180–220 kg, the system is designed to keep the wires working consistently during continuous cutting, helping reduce wire deviation and improve cutting stability.
This is particularly important when running 72- or 86-wire configurations, where maintaining uniform wire behavior becomes increasingly critical.
Automatic Wheel-Wear Compensation
Consistent Precision Throughout Production.
The automatic compensation system adjusts for wheel wear to help maintain accurate wire positioning and stable slab thickness while reducing manual adjustment.
Patented Column Lifting & Feeding System
Precise Feed. Smooth Movement.
Precision linear guides and servo-driven vertical feeding provide accurate cutting-depth control and stable movement throughout the cutting process.
Wire-Breakage Alarm & Automatic Slab Divider
Safer Cutting. Less Downtime.
The wire-breakage detection system responds quickly to broken wires, while the automatic slab divider separates cut slabs progressively, reducing manual intervention.
Variable-Frequency Main Drive
Power Matched to the Cutting Process.
The variable-frequency drive allows wire speed to be adjusted between 20–35 m/s according to stone type and cutting conditions, helping optimize cutting efficiency and wire performance.
Wear-Resistant, Replaceable Rubber Strips
Durable Performance. Easy Maintenance.
Replaceable wear-resistant rubber strips extend wheel service life and make maintenance faster and more economical.
Intelligent CNC Control
One-Touch Operation. Real-Time Monitoring.
The intelligent CNC/PLC system provides intuitive operation, real-time monitoring, alarm management and production data recording for easier and smarter machine management.

Frequently Asked Questions
Q: What is the STONEX HLMW-U Multi-Wire Saw Machine?
A: The STONEX HLMW-U is a high-efficiency stone block cutting machine for producing multiple granite, marble and quartzite slabs simultaneously. It is available in 42, 56, 72 and 86-wire configurations for different production capacities.
Q: How many slabs can the HLMW-U cut at one time?
A: Depending on the model, the HLMW-U can cut up to 41, 55, 71 or 85 slabs in one cutting cycle. The actual slab quantity depends on the selected wire configuration and slab thickness.
Q: What size stone blocks can the HLMW-U cut?
A: The HLMW-U provides a maximum cutting length of 3,500 mm and cutting height of 2,200 mm, making it suitable for large granite, marble, quartzite and other natural stone blocks.
Q: What diamond wire sizes and slab thicknesses does it support?
A: The machine supports 5.3 mm and 6.3 mm diamond wires and standard 20 mm or 30 mm slab thicknesses. The 5.3 mm wire option helps reduce kerf and improve stone-block utilization.
Q: How does the HLMW-U maintain consistent slab thickness?
A: Its two-column symmetrical triangular wire-path, balanced tensioning system, precision servo feeding and automatic wheel-wear compensation work together to maintain stable wire positioning and consistent slab thickness throughout production.
Q: What makes the HLMW-U different from a conventional multi-wire saw?
A: The HLMW-U combines a symmetrical triangular wire-path with balanced wire tension, automatic wheel-wear compensation, wire-breakage detection and intelligent CNC control. This combination improves cutting stability, reduces manual adjustment and supports consistent high-volume production.
Q: How do I choose the right HLMW-U model?
