Multiwire is the youngest stone cutting machine. This machine cuts the coup stone into slabs with a number of wires on which there are diamonds. The stone cup is placed under the machine. Then, by moving the wires, the coop cuts the slab. In the rest of this article, the advantages and the method of its operation are explained. Be with us so that in addition to introducing this big device, we will also introduce its domestic and foreign manufacturers.
What is the advantage of multiwire over saw?
Multiwire is gradually taking the place of saws in Iran and other countries of the world. But what are the most important advantages of multiwire?
Speed The speed of stone cutting in multiwire is much higher than that of stone cutting saws. The reason for this difference is in the different structure of these two devices. For example, granite is a hard stone. Cutting it with a saw takes a few days to a week. If a multiwire machine can cut granite slabs in a few hours. The most important advantage of multiwire is when cutting granite. Despite the high hardness of granite, Multiwire can cut in the shortest time and with high quality. Granite slab processing can be done for stones that are practically free of cracks and health with the sawing machine system. Factories that are active in this field are trying to buy and install multiwire devices. To be able to do this with very high speed and accuracy. It only takes a few hours to cut a coupe stone. If we assume that the average speed of the wire inside the stone is between 15 and 20 cm, this device can finish a stone that is about 2 meters in about 10 to 12 hours. Meanwhile, in granite saw systems, it takes about a week to cut such a stone.
The possibility of changing the thickness Another advantage of multiwire is the possibility of changing the thickness by changing the distance of the wires. Since this machine is completely CNC and computerized, changes are made with computer settings in the machine. The user can adjust the distance between the wires according to the customer’s order. Therefore, the use of the multiwire device can be of great help to the producers to increase the volume of production and more economical production.
Back tension as a result of less damage: The cutting mechanism in multiwire is based on the application of tension by the wire. This mechanism is such that the distortion in the wire is eliminated. If cutting with a saw is done by steel blades with diamonds. These blades, which are responsible for cutting the stone, create more tension. Of course, the possibility of damage, breaking or cracking is much less in multiwire.
Multiwire and nothing else?!
Although the quality and quantity of stone production increases with the use of a multiwire device, it should be noted that the product output from this device is only in the form of slabs. In other words, to produce tiles of different sizes, slab stones must be re-cut, which will increase the cost of stone tile production.
Familiarity with scratch payment
Therefore, the use of the cutting machine for tile production is more economically justified, and the multiwire machine has significant advantages only in the production of stone slabs.
Most of the large stone-cutting companies in Iran have turned to using multiwire devices, while smaller production units still use saws and chisels. It should be mentioned that the market of the stone industry needs both types of slab and tile products and each of these devices has its own advantages.
Multiwire diamond cutting wire
One of the challenges that always exists in the use of a multiwire device is the price of its diamond cutting wire. Due to the high price of these diamond wires, the cost of stone processing with the multiwire machine is higher than that of the saw cutting machine, and it is justified only for cutting blocks of granite stones or blocks of vulnerable stones such as onyx.
