Why the Multi Blade Granite Cutting Machine Is So Popular in Stone Processing Industry



Gang saw cutting process is not continuous, so its cutting speed is relatively too low. Its low cutting speed has heavily restricted the improvement of stone cutting efficiency. So, a new kind of stone cutting machine is created to solve the problem. That’s diamond circular saw stone cutting machine. This machine is composed of machine body, blade driving motor, diamond circular saw, blade rise/fall guide system and blade horizontal moving guide system, etc. It cuts stone by the diamond circular saw running at high speed and reciprocation movement along horizontal guide rails on the cross-beam. Meanwhile, diamond circular saw falls along vertical guide rail to feed to stone block.

Diamond circular saw stone cutting machine has higher cutting speed than gang saw machine and greatly improves stone processing efficiency. So, diamond circular saw stone cutting machine is the most widely used stone processing equipment nowadays. But it comes with a disadvantage. The circular saw stone cutting machine maximum cutting depth is determined by the circular saw diameter. Usually it can’t exceed circular saw diameter.

It’s said that the biggest circular saw stone cutting machine was manufactured in Germany in 1980. The circular saw diameter was 5 meters. But the blade driving spindle is not strong enough to bear a so heavy saw blade to make vertical stone cutting. Secondly, due to that the circular saw diameter is really too big, the slab surface cut by it is not smooth. So, it is difficult to make the circular saw into a very big diameter, in view of technical aspect. Even though that circular saw stone cutting machine has much higher linear speed than gang saw machine, it can’t cut as deep as gang saw and can’t produce so many pieces stone slab as gang saw at a time. Therefore, circular saw stone cutting machine can’t replace gang saw machine in cutting big size slab.

To furtherly improve stone processing efficiency, multi blade granite cutting machine is created based on single blade circular saw stone cutting machine. In this kind machine, many pieces circular saw are installed on a long spindle with spacer in between to cut stone. Though there is not much change is machine structure, the multi blade granite cutting machine can be mounted as many as one hundred pieces circular saw. So it is able to cut 100 pieces stone slab at a time with very high cutting efficiency.

To get higher level of automation in the multi blade block cutting machine, people add a horizontal blade to the machine. After the vertical blades cut stone block into slabs, the horizontal blade cuts slab off from the stone block. It not only reduces human labor work, but also reduces production cost.
