Stonewin offers multi wire saw machines for cutting granite and marble blocks into slabs. The material assessment should cover the actual block, the selected machine and the diamond wire configuration.

1.Granite and marble block cutting

Granite and marble should be evaluated with their origin, block dimensions and required slab thickness. A commercial stone name alone does not describe every processing condition. When requesting a proposal, include photographs and any existing cutting records so that Stonewin can assess the application.

2.Other natural stones need an application review

For other natural stones, including materials marketed as quartzite or luxury stone, suitability should be assessed before equipment selection. Abrasiveness, mineral composition, cracks and structural variation can affect the proposed cutting process. A general description of natural-stone capability is not confirmation for every material.

3.Match the diamond wire to the material

Select the bead specification and diameter together with the machine configuration and the stone. Wire speed, feed, tension and cooling must suit the application. Do not transfer a successful setting from one stone to another without an appropriate review.

4.Information to send for an assessment

Provide the stone name, origin, clear photographs, typical and maximum block dimensions, target thickness and known defects. Mention any previous cutting difficulties. Stonewin may recommend cutting trials when cracks or variable composition make performance uncertain.

The core process and technical points of Stonewin multi-wire cutting machine for processing marble slabs are as follows: 

 I. Equipment structure and working principle 

1.Multi-wire cutting system 

- Diamond wire saw (diameter 6.3-7.3mm) is used to achieve high-precision cutting, and 57-85 plates can be cut at a single time (depending on the model) 

- The main motor power is 180-250kW, the line speed is 0-35m/s adjustable, and the cutting path can be controlled by the PLC system. 

2.Automated control 

 Equipped with a laser tracker to monitor the shape of rough materials in real time and automatically optimize the cutting scheme to reduce waste. 

 Support three-dimensional three-dimensional cutting, and control the saw blade to walk independently at different heights through the program. 

 II. Processing process 

1.Rough material pretreatment 

- Check the size of the rough material (maximum 3300×3500×2000mm), and the bottom surface needs to be repaired first. 

- Identify defects such as color spots and dark cracks, and process them in segments as needed (for example, when the color line width is ≥200mm) 

2.Cutting stage 

 -After the rough material is fixed, the thickness tolerance (20mm±5mm) should be checked immediately after the first three pieces are cut. 

 -The cooling water flow rate is 1800L/min to prevent the diamond rope from overheating. 

 3.Post-processing 

- After cutting, the plate is trimmed by a horizontal cutting machine, and the leveling machine uses 4 sets of diamond grinding wheels (particle size 46-1000 mesh) to level. 

- The polishing line adopts 14 grinding heads (the first 10 grinding + the last 4 polishing), and finally grinding the edge chamfer. 

 III. Technical advantages 

- Efficiency improvement: Compared with traditional sand saws, the yield rate is increased by 10%-25%, and the daily production capacity can reach 2500m2. 

- Environmental protection: reduce wastewater and waste by 80% and reduce noise by 50% 

- Ultra-thin processing: directly cut 3mm thin plate without secondary processing

The Stonewin series multi-wire saw machine is mainly used for the cutting and processing of stone materials such as granite, marble, and luxury stones.

Stonewin multi-wire saw machine has core advantages over traditional large-plate processing equipment for cutting large slabs, which can help you achieve higher quality and quantity of large sheets in a shorter time.

Higher output numbers: Compared to traditional saws, the stonewin multi-line cutting machine increases output numbers by 10% to 25%, resulting in an increase of 8 square meters of plate material per cubic meter of raw material.

Ultra-thin processing: It directly cuts ultra-thin plates, without requiring secondary processing.

Environmental protection and energy conservation: The cooling water is recyclable, reducing the waste water and mud rate by 80%, and noise by 50%.

Automatic control: It uses a PLC system and supports adjustment of line speed from 0 to 35 m/s.
