RSHJ-1400/2400 Automatic Diamond Segment Brazing Stand

Precision Automatic Welding Solution for Large-Scale Saw Blade Production

For diamond saw blade manufacturers, the weakest link in finished product quality is often the brazing joint. Manual welding struggles to balance speed, precision and stability, making it hard to guarantee consistent quality for mass-produced blades. The RSHJ series automatic brazing machine targets this pain point, using standardized process control to eliminate human error, ensuring every segment is perfectly welded onto the blank.

The two models cater to different production needs and blade sizes, with the option for custom specifications.

1. RSHJ-1400: The compact, cost-effective model is ideal for producing standard bridge saw blades and mid-sized cutting discs, perfect for small to mid-sized manufacturers.
2. RSHJ-2400: The heavy-duty, extended model is designed for large-diameter mining saw blades up to 2500 mm, built for continuous, high-volume production in large-scale factories.

Micron-Level Precision Control for Blade Stability

The machine maintains verticality within 0.03mm and parallelism as tight as ±0.03mm. This ensures every segment is perfectly aligned, eliminating wobble, uneven wear, and premature segment loss. The result is longer blade life and consistent cutting performance, which directly improves customer satisfaction with your products.

Standardized Brazing Process Eliminates Quality Fluctuations

With a fixed 3–5 second welding cycle, the machine delivers uniform heating and pressure for every segment. Cold joints, virtual welding, and human error are completely eliminated. This drastically reduces defective products and rework, which are common headaches in manual production.

Continuous Operation with Stable Cooling System

The integrated water cooling system (2m³/h at 0.2MPa) keeps the welding head at a constant temperature, preventing overheating during long shifts. Combined with a stable 0.5–0.8MPa air supply, it ensures consistent clamping force and brazing quality around the clock.

Simple Operation Reduces Labor Dependence

The intuitive touchscreen control allows you to save recipes for different segment sizes and blade types. New operators can start production quickly, freeing experienced technicians for quality control or other tasks. One worker can easily manage multiple machines, significantly lowering labor costs.

✅ Mid-sized saw blade factories: Mass production of standard bridge saw blades, tile cutters, and hand-held tool discs.

✅ Large mining blade manufacturers: High-volume production of large-diameter quarry and block cutting blades.

✅ Custom saw blade OEMs: Versatile equipment for a wide range of standard and custom blade specifications.

1. Higher Product Quality: Precision brazing leads to more reliable, longer-lasting saw blades, enhancing your brand reputation.
2. Lower Production Costs: Reduced labor requirements, lower reject rates, and fewer consumables translate directly into improved profit margins.
3. Scalable Solution: Start with the compact model and upgrade to the larger model as your business grows. Customizable sizes are available for unique production needs.
