This is a concise summary by engineers on the use of diamond saw blades for stone cutting — essential knowledge you should not overlook:

 

 

The raw stone block must not be smaller than 0.5m3. It should be placed securely with square timber pads underneath to stabilize it. The block must be positioned symmetrically on the working platform to ensure the stability of both the platform cart and the block itself. No shaking or vibration is allowed.

 

 

The saw blade must run idle and remain stable before trial cutting. Never start the blade with its edge already in contact with the stone. During cutting, the blade must not stop rotating; stop rotation only after the blade has been fully withdrawn from the cut.

 

 

If any movement of the block is detected during cutting, the operation must stop immediately. Only after the block is securely fixed again can cutting resume. During the cutting process, the block must not be moved arbitrarily.

 

 

Especially when using a new blade core, let the blade idle for about 30 minutes. In hot summer conditions, idle with water cooling. This process helps eliminate residual stresses caused by welding the segments and enhances the blade’s structural memory under high-speed rotation.

 

 

Adjust the limit switches according to the length, width, and height of the block, ensuring the blade’s lifting and trolley travel are within a safe and effective range. Before cutting, the blade should be 10–20 mm above the block. After cutting, leave a distance of 20–40 mm between the blade and the bottom of the block. Before the blade moves laterally, it must be fully withdrawn from the cut, with a clearance of at least 150–200 mm to prevent collision with the stone block.
