The history of stone cutting in the world dates back to 3000 BC, when man was able to cut stone with axes and simple tools such as tools. Decorative Objects. Make nuts and even bowls. In order to cut hard stones such as marble and granite, early humans first made holes with a hammer and used wood to make wooden wedges and placed them in these holes, and then by wetting these wedges and expanding and Shrinkage During the day and night, cracks formed in the rocks that could easily break the rock. Later in the Bronze and Iron Ages, this was done using hammers and bronze tools.

In the 1400s, with the creation of mill wheels, better methods were created for polishing stones. In this method, two convex stones are used to polish sample stones. This is despite the fact that in this decade, sculpture cuts were still made with axes and hammers. The city of Aidar-Oberstein, Germany, was the first city to be cut in the late 14th century by miners found in agate mines.

In the late eighteenth and early nineteenth centuries with the beginning of the Industrial Revolution in Europe. The invention of the steam engine and the first steam engine to extract water from mines. Exploitation and extraction from mines increased in 1926, a blade was invented that could cut building materials such as bricks, etc. The cut was made using diamond chips embedded in a metal body.

In 1936, with the invention of electric masonry, cutting methods changed and over the course of forty years, the number of stone producers and cutters increased. These saws have been widely used over the years and have worked mainly with either 120 or 240 volts or a small gasoline engine. All of these cutting machines worked in the vicinity of water and in wet conditions. The masonry saws were divided into two categories of 14 and 20 inches.

Dry abrasive blades were also used in the 1950s and 1960s. Although they cost much less than diamond blades, they had many drawbacks: the blades would wear out very quickly. They made a lot of dust. In addition to walnut soil, the cutting of sandstone from the silica that was poured on the blades, and in some cases with asbestos, was dangerous for human respiration. During this period, cutting stone with smooth was not a fixed option and gradually changed in the 80's and diamond machines and type of cutting were developed with more precision and speed.

Stone cutting in Iran

The first stone cutting machine in Iran was built in 1307 AH at the same time as the construction of the Marble Palace with iron blades that worked with powder and silica and was known as sawdust in the Naziabad area of ​​Tehran. The next device was set up in 1961 by Goldschmidt of Ashkoda Company in Tehran Bazaar for the construction of Bank Melli and the courthouse. But the first stone cutting factory in Iran was built in 1317 by German experts on the order of Astan Quds Razavi in ​​Mashhad. The stones of the holy shrine of Imam Reza (AS) and the Central Bank of Tehran, Sepah Bank and Marble Palace were produced by this factory.

The peak machine on this factory, which was known as the saw, had 40 steel blades that moved with a distance of 3 to 5 cm by one arm, and from the top of the blades, water was constantly sprinkled on the blades and stones, and powder was cut to cut the stone. Silica was sprayed on the stone by the worker to place the silica powder between the steel blade and the stone and to cut it by pressing the blades on the stone. In 1320, Eshkora Company and Iranian partners set up a stone-cutting factory in Javadieh neighborhood of Tehran, and at the same time, Naziabad factory expanded its factory and increased the number of stone-sawing saws to eleven, and the stones of Imam Hussein's shrine in Karbala. And they produced the shrine of Hazrat Ali in Najaf Ashraf.

In 1345, there was a change in stone production and with the installation of gate cranes and stone saws with diamond blades, stone production became massive and the number of stone cutters in Tehran, Isfahan and neighborhoods increased significantly. Exploration, extraction, transportation, cutting and sawing, which have been common in Iran over time by traditional and manual methods, have made significant progress in recent times. Most stone cutting factories either use the latest machines in the world or use domestically made machines and machines that are of acceptable quality.
