RS Series Porous Mine Saw Blade Base

High Rigidity Perforated Saw Blank For Quarry Double-Blade Mining Machines

Saw blade base is the core carrier of diamond segments for stone mining. Inferior ordinary steel substrates suffer from easy deformation, serious blade swing and short service life under heavy deep cutting load, forcing mine operators to frequently replace saw discs and raising daily production cost. Our porous hollow mining saw blank adopts exclusive special alloy steel raw material, going through standardized full-process precision manufacturing. Multiple diameter specifications cover mainstream 2000–5200mm mining machine matching demands, specially customized for open-pit granite & marble quarry mining equipment.

Complete Standard Technical Parameter Table

Strict Standardized Full Production Workflow

Every saw blank undergoes 6 core standardized production links to guarantee consistent mechanical performance of finished substrates:

1. High-Quality Special Alloy Steel Plate Raw Material Selection We source exclusive wear-resistant special steel plates as raw materials, compared with ordinary carbon steel, it delivers stronger tensile strength and anti-fatigue performance, laying the foundation for long-cycle heavy-load mining cutting.
2. Precision CNC Laser Cutting Forming Adopt large-format laser cutting equipment for one-time integral cutting of saw disc outline, tooth slots and hollow heat dissipation holes. Cutting edge is smooth without burrs, ensuring perfect matching assembly with diamond segments later.
3. High-Temperature Integral Quenching & Tempering Treatment Complete secondary heat treatment through constant-temperature quenching furnace. The internal metal grain structure of the steel plate is optimized, effectively eliminating internal stress generated during cutting, fundamentally solving long-running deformation and swing defects.
4. Secondary Constant-Temperature Stress Relief Quenching Deep stress relief process removes residual thermal stress after high-temperature treatment, preventing warping or uneven flatness of large-diameter saw blanks after long-time rotation.
5. Multi-Dimension Precision Inspection & Calibration Specialized testing equipment detects flatness, concentricity, hardness and thickness of every finished blank one by one. Unqualified semi-finished products are eliminated directly to avoid defective substrates flowing to mines.
6. Finished Product Classification & Warehousing Classify saw blanks by diameter, thickness and tooth quantity, with protective packaging to prevent collision deformation during transportation.

Core Product Advantages For Quarry Production

1. Special alloy steel raw material, outstanding rigidity & long service cycle

Customized special steel formula greatly improves anti-fatigue performance. Under long-hour deep cutting of hard granite, the saw blank keeps stable flatness, no obvious blade swing, extends the whole saw disc service life, and reduces frequent saw disc replacement downtime for mines.

2. Porous hollow design with excellent chip removal & cooling effect

Uniformly distributed hollow heat dissipation holes across the disc surface form an unobstructed circulation channel for cooling water. Cutting heat and rock powder can be discharged rapidly during operation, avoiding high-temperature softening of the steel substrate and diamond segment burning loss, lowering segment wear speed.

3. Lightweight hollow structure cuts mine electricity consumption

The hollow design reduces the overall weight of the large saw disc. Mining machine main motor bears lighter rotation load, which can effectively cut hourly power consumption for quarries running three shifts nonstop all year round, lowering daily energy expenditure.

4. Low swing precision forming, less loss of diamond segments

Laser precision cutting + dual heat treatment eliminate internal stress, the saw blank runs smoothly without shaking at high rotating speed. Uniform cutting force reduces unilateral abrasion of diamond segments, saving long-term consumable procurement cost for mine owners.

5. Complete size spectrum, compatible with all mainstream double-blade mining machines

Diameter range covers 2000mm small mining saws up to 5200mm super-large heavy-duty mining machines, unified 100mm standard inner hole. It can be directly matched with RSZL series four-wheel drive gear direct-drive mining machines and traditional belt-type double-blade mining equipment, no secondary transformation required.

Target Application Customers & Usage Scenarios

1. Open-pit granite & marble mining yards equipped with double-blade mining machines
2. Saw disc processing factories engaged in diamond saw blade welding and sales
3. Large stone mining industrial parks with high daily raw block output
4. Foreign trade mining equipment supporting accessory suppliers exporting mining saw blanks overseas

Visible Economic Benefits For Mine Operators

1. Cut consumable replacement frequency: Anti-deformation high-rigidity substrate extends the whole saw disc service life, reducing shutdown times for saw disc swapping.
2. Reduce segment loss: Good cooling and stable rotation lower segment wear speed, cutting monthly diamond segment purchase cost.
3. Save power operating cost: Lightweight hollow design lightens motor load and decreases long-term electricity bills for round-the-clock mining.
4. Minimize waste rock rate: Stable running saw blank produces neat cutting kerfs, lowering irregular raw block scrap loss caused by blade swing.
