About the stone slabs or stone saws
Cut using saws Cutting of stone by sawing is the most common method in stone mills. Cutting saws are mainly used in factories with high production capacity. In this way, the stone block is cut by a series of parallel saws with diamond blades. Diamond saws have different blades and power, usually 40 to 80 blades. The saws are divided into soft and hard groups. 1-1-1-1- The soft saw Soft saw machines are used to cut calcareous gems. The advantages of this cutting machine are relatively low and precise waste. The most commonly used devices have three types of diamond saw blades: - The first type in which the block stays on the wagon and the blade unit is lowered.
- The second type, in which the blade unit remains constant at a certain height, and the block in the vertical direction is raised. - The third type in which the blade unit is in the vertical position and the block moves horizontally. 1-1-1-2- Hard drive In hard saws, instead of diamond blades, the stone is cut off using cast iron or steel. Hard saws have a few hundred to several hundred blades and the largest number of blades is 150 in new machines. Modern saws can cut blocks of 330 * 350 * 200 cm. It is worth noting that the hard-core substitutes (granite rocks) are more difficult because of the high hardness and the cost is higher. This also increases the price of hard rock on the market.
1-1-2- Cut to the top Peaks have different types and dimensions. At the summit, circular blades (discs) are used with diamond segments. The diameter of the discs starts at 15 centimeters or less and reaches about 300 centimeters. In this way, the block of stone is cut by one or more parallel disks in the form of a plaque. Stone cutting is done in a single-step or multi-stage method. A one-step method is used for soft and semi-hard rocks and a multi-stage method for cutting hard rocks. The important thing is that about 20% of the diameter of the blades can be cut in depth, so increasing the cutting dimensions should increase the diameter of the discs by a factor of several times, and because of this limitation, this peak machine does not have much efficiency at high output.
Peak is used more on Tayl's production line and the sex of segments is diamond.
At the peak of the cutting deck, the soft and semi-hard gems of the disc are as full as the plain plain, and all of them suddenly enter the stone, which is referred to as a one-step cutting method. Multi step cutting system is mainly used for cutting granite and rocks with high quartz and high hardness. In this way, several vertical discs that run on the same stretch make the stone cut in several steps. Thus, at each step, it penetrates just a few centimeters in the rock, and at the same time the center-level discs, sometimes reaching 30 to 40 discs, make a few millimeters to several centimeters of slice, and then repeat this repeat And it continues to end with the ultimate depth.
The basic difference between single-step and multi-step cutting methods is how the discs move after each cutting step. In a one-step cut after vertical cutting, the disc returns and is ready to cut the next plaque, but in a multi-step cutting procedure, after each cutting step, for the next cutting of the discs, moving backwards the vertical transfer movement to the bottom have. Also, in a one-step cut, if the unit is a single disc, there is complete flexibility to change the thickness of the stone as desired, but in a multi-stage cut, the thickness of the cut stone can only be as large as the distance between the vertical discs, and no change in The thickness of the stone can not be applied.
The depth of cutting and the number of sheets produced by the summit are limited in such a way that it cuts up to a maximum of 120 cm.
The cutting depth should be adjusted to provide a speed of 2.5 to 3 meters per minute. Use water or other coolant materials to cool diamond blades. One of the reasons that causes the wear and tear of the steel body to beneath the section is the connection of the segments with the body, the lack of proper use of water and the lack of rapid cutting of the cuttings. This is one of the reasons why too much water gets too hot at the time of cutting, which causes the cleavage and early destruction of the segments.
The diamond blade should be used with a suitable volume of water. The flow of water to cool the saw blade should be between 5 and 10 liters per minute. 1-2- Decorative stone processing machines with cutting tools: The stone processing industry is moving faster and more efficiently to produce better, lower quality and costly products, and builders of different types of stone machines also produce different types of machines. One of the new stone processing machines is a cutting machine with wire. Stone cutting machines with wire are produced in several models:
- Cutting machines with a wire and perpendicular to the hard and soft rocks. - Stone cutting machines from 5 to 20 wires in a constant and variable method for hard and soft rock cutting. - Stone Cutting Machines with 60 Wires in a Fixed Method for cutting soft and hard rocks in place of a Blade Saw Blade. - Stone cutting machines for all types of three-dimensional design for cutting soft and hard rocks.
