Bronze chisels can indeed be used to cut granite, although the process is more challenging compared to using harder tools like diamond-encrusted chisels or modern cutting equipment. Historically, ancient civilizations such as the Egyptians used bronze tools to work with granite. They employed techniques like hammering and chiseling to shape and cut the stone.

Ancient Techniques

Chiseling and Hammering: Ancient Egyptian stone masons used bronze chisels along with wooden mallets to chip away at the granite. They would create grooves and then use wooden wedges soaked in water to expand and split the rock.

Pounding with Dolerite: For harder stones like granite, they also used a technique called hammer and dolerite pounding. Dolerite, a hard volcanic rock, was used to create fractures in the granite, which could then be split using wooden wedges.

Modern Considerations

While bronze chisels can cut granite, the process is labor-intensive and requires a high level of skill. Modern stone masons typically use diamond-encrusted tools for greater efficiency and precision. If you are working with granite, consider using diamond-tipped chisels or saws for cleaner and faster results.

Tips for Using Bronze Chisels

Continuous miners can indeed cut through granite, but the process is challenging due to granite's high hardness and compressive strength.Here's a detailed look at how continuous miners can be used for granite cutting:

Challenges of Cutting Granite with Continuous Miners

Granite is an extremely hard rock with a compressive strength that can exceed 200 MPa.This high hardness makes it difficult for traditional continuous miners to cut through granite efficiently. The carbide cutting bits used in continuous miners must be able to penetrate and fracture the granite without wearing out quickly.

Techniques and Equipment for Cutting Granite

High-Pressure Waterjet Assistance: Using a high-pressure waterjet to create free faces in the granite can significantly reduce the cutting forces required by the continuous miner.This technique involves directing a high-pressure waterjet at the rock to create initial fractures, which the continuous miner can then exploit to cut more efficiently.

Specialized Cutting Tools: Continuous miners equipped with carbide-tipped cutting tools are more effective at cutting granite.These tools are designed to withstand the high forces and wear associated with cutting hard rock.

Dynamic Undercutting Method: Some continuous miners, like the Komatsu MC51, use a dynamic undercutting method to cut through hard rock.This method involves creating an undercut in the rock, which allows the continuous miner to cut more efficiently and with less wear on the cutting tools.

Practical Applications and Case Studies

Komatsu MC51: This hard rock continuous miner has been tested in granite mines with compressive strengths of up to 250 MPa.The machine demonstrated the ability to advance 3 to 4 meters per shift, which is competitive with traditional drill and blast methods.

Wirtgen Surface Miners: These machines are designed for cutting a variety of rocks, including granite.They use a combination of cutting drum technology and high-pressure waterjets to cut through hard rock efficiently.

Corundum blades can cut granite, but they are not the most efficient or commonly used option for this task. Here's why:

Hardness Comparison

Granite: Granite has a Mohs hardness of 6-7. It is a hard stone that requires durable cutting tools.

Corundum: Corundum has a Mohs hardness of 9, making it significantly harder than granite. This high hardness means corundum tools can cut through granite, but they are not typically used for this purpose.

Practical Considerations

Diamond Blades: Diamond blades are the industry standard for cutting granite. They offer superior hardness (Mohs 10) and durability, making them more efficient and longer-lasting for cutting hard materials like granite.

Efficiency: While corundum is hard enough to cut granite, diamond blades are more efficient due to their higher hardness and better heat dissipation properties. Diamond blades can handle the high forces and heat generated during cutting without wearing out quickly.

Specialized Tools: For cutting granite, specialized diamond blades with turbo segments or continuous rims are recommended. These blades are designed to handle the hardness and density of granite, providing clean and precise cuts.
