Customizable Mine Cutting Disc Blanks Manufacturer

Hollow Segmental Diamond Saw Blade Blank for Quarry (Mining Series)

Model Range: Φ2000 – Φ5200 | Ruisheng Machinery

Ruisheng Machinery is not only a leading manufacturer of heavy-duty stone processing machinery but also specializes in the R&D and production of high-performance diamond tool blanks. Our Hollow Segmental Saw Blade Blanks (Mining Series)​ are engineered specifically for open-pit quarrying, featuring a patented composite porous structure​ that solves the common pain points of traditional solid blanks - excessive runout, high energy consumption, and thermal deformation under ultra-large diameter cutting.

Key Features & Advantages

🪶 Lightweight Composite Structure

The scientifically engineered hollow layout significantly reduces the overall blade weight, lowering the load on the main motor and cutting power consumption - all while maintaining exceptional mechanical strength.

🎯 High Rigidity & Low Runout

Made from premium specialty alloy steel and processed with precision heat treatment, the blank remains flat even under high-speed rotation and extreme cutting pressure. Minimal wobble​ extends the life of diamond segments and improves cutting accuracy.

💨 Superior Slurry Discharge & Cooling

The perforated design creates an internal airflow channel that enhances chip/slurry removal. Combined with optimized water channels, the blank delivers excellent cooling performance, preventing thermal deformation during long, intensive operations.

Production Process (Quality Assurance)

Ruisheng operates a full in-house production line from raw material to finished product:

1. Premium Steel Plates​ - Strictly selected specialty alloy steel as the base material.
2. Laser Cutting​ - CNC laser cutting for burr-free, high-precision blank profiles.
3. Quenching & Heat Treatment​ - Advanced thermal processing to maximize hardness, toughness, and wear resistance.
4. Precision Finishing​ - Secondary precision cutting ensures geometric accuracy of the porous sections.
5. Final Inspection​ - Strict QC on flatness, dynamic balance, and dimensional tolerance before shipment.
