• You work with ultra-thin slabs (3-15mm) that might crack under blade pressure

Many successful fabrication shops eventually invest in both technologies, starting with the saw that best matches their initial market focus. DINOSAW offers hybrid options that combine wire and blade capabilities for workshops seeking maximum versatility.Maintenance and Operational Questions

How can I extend the life of diamond saw blades when cutting hard granite?

A: To maximize diamond blade life when cutting hard granite:

1. Proper break-in procedure: Cut soft material (limestone or concrete) for the first 50m² to gradually expose diamond particles

2. Optimal rotation speed: Maintain 35-45m/s peripheral speed - too fast accelerates wear, too slow reduces cutting efficiency

3. Consistent water cooling: Ensure 15-20 liters/minute of clean water to prevent overheating and thermal damage

4. Appropriate feed rate: Use 0.5-1.5m/hour feed rate for granite depending on hardness - listen to the motor sound to detect overloading

5. Regular blade dressing: When cutting efficiency decreases, make 2-3 cuts in abrasive material like brick to re-expose diamonds

6. Inspect mounting flanges: Ensure flanges are flat, clean, and properly tightened to prevent wobbling

DINOSAW's granite-specific blades with optimized diamond concentration and bond hardness can achieve 30-40% longer life than standard blades when following these practices .

What's causing my rock cutting saw to make excessive noise and vibration?

A: Excessive noise and vibration in rock cutting saws typically stem from six common causes, each with specific solutions:

1. Blade/wire issues:

• Inspect for worn segments, cracks, or deformations

• Check if tension is uniform (for wire saws)

• Verify blade is appropriate for the material being cut

2. Mounting problems:

• Ensure flanges are flat, clean, and properly torqued (40-60 Nm typically)

• Verify blade hole diameter matches arbor exactly

• Check for debris between flanges and blade

3. Bearing wear:

• Test for arbor play (should be less than 0.05mm)

• Listen for characteristic bearing whine

• Replace bearings in pairs if wear is detected

4. Misalignment:

• Verify blade/wire is perpendicular to travel direction

• Ensure guide rails are parallel and level

• Check motor and arbor alignment

5. Material feed issues:

• Confirm consistent feed pressure

• Ensure material is securely clamped

• Verify feed speed matches material hardness

6. Structural resonance:

• Inspect machine foundation and mounting

• Check for loose components amplifying vibration

• Verify machine is level and properly anchored

DINOSAW's remote diagnostic service can analyze vibration patterns to pinpoint exact causes before they lead to equipment damage or dangerous operating conditions.
