best diamond blade for cutting granite

Sintered Stone is a new type of porcelain material made from natural raw materials through special process, with the help of a press of more than 10000 tons (more than 15000 tons), combined with advanced production technology, and fired at a high temperature of more than 1200 ℃, which can withstand cutting, drilling, polishing and other processing processes.

The sintered stone has high hardness. Ordinary marble and granite saw blades cannot be used to cut the sintered stone. Even if it can be cut, the cut products will be prone to edge collapse, serrated edge and low cutting efficiency. Therefore, the special saw blade for cutting rock plate shall be used for cutting.

The special sintered stone cutting medium-diameter saw blade developed and produced by our company has the characteristics of sharp cutting, smooth cutting and no edge collapse. Select high-quality diamond for long-term cutting, which is more stable and has high cutting accuracy.
The low-cost saw blade on the market is produced by stamping, which leads to non-standard substrate aperture. Our company uses laser cutting technology, and the aperture uses honing and reaming technology to ensure that the aperture of each saw blade meets the high accuracy requirements. The error rate is<=0.02, and the international standard is 0.06. The large aperture error will greatly increase the possibility of vibration, curve cutting, and stone edge collapse when the saw blade is cut

[Product Parameter]

Thickness: 2.2/2.6/2.8

Arbor: 25.4/50/60

Applicable to bridge cutting machine, 45 ° bevel cutting machine, etc.

Use Recommendation 1:
Cutting speed: 0.8-1.2 m/min
Motor saw blade speed: 2800-3200 rpm
The new saw blade needs to be cut with sand brick or refractory brick.

Use Recommendation 2
Because the Sintered Stone(rock plate) is a material with high hardness and high density, a large amount of water should be used to assist the cutting to fully cool the blade. The cooling water should be sprayed directly to the cutting point where the blade contacts the plate. It is recommended that the cutting speed of the first 30cm and the last 30cm should be kept at 0.6m-0.75m/min, and the straight advancing speed of the 45 ° bevel cutting should be 0.5m/min to ensure the flatness of the cutting surface

Use Recommendation 3
The saw blade suitable for cutting one type of rock plate may not be suitable for cutting another type of rock plate. If the cutting efficiency is found to be low, and the cutting edge has sawtooth, rock plate burst, and fracture, it is necessary to find a suitable saw blade for cutting in time.

Use Recommendation 4
In the process of cutting rock slabs, you can't drive the machine very fast, like cutting natural stone slabs, and make a loud noise. The faster the cutting speed is, the greater the impact on the rock plate will be, and the more likely the rock plate will collapse, drop corners, burst or break under the strong impact force.

Use Recommendation 5
When the operator of the bridge cutting machine gets the saw blade of the rock plate, pay attention to the cutting speed recommendation table on the paper box that packages the saw blade of the rock plate. It is appropriate to cut the rock plate with the cutting speed parameter recommended above, or slightly higher than the recommended cutting speed.

Use Recommendation 6
It is the most basic principle to cut stone boards from the largest size products first and then the smaller size products. However, many bridge cutters may not follow this principle. They often cut products with uniform size and large quantity first, and then cut products with small quantity. The precondition for this is that there is no product scrap or wrong size cut during the cutting process.

Use Recommendation 7
In case of corner falling and cracking at the cutting edge of the rock plate during the cutting process, you can find a small piece of rock plate or wood bar to hold the small piece of rock plate to be cut, or use a rock plate with a width of 100mm and a length of about 200mm to cross the cutting edge and top it on the end face of the rock plate to be cut, which can prevent the rock plate from bursting at the cutting edge when sawing the rock plate.
