Can I Use the Same Machine for Marble and Granite?

In the stone processing industry, a common question often arises:

"Can I use the same machine to process both marble and granite?"

The answer is: Yes — but only with the right tools and proper settings.


 1. Understanding the Difference Between Marble and Granite

Although both are popular natural stones, their physical characteristics vary greatly:


Marble is relatively soft (Mohs hardness: 3–4), easy to cut and polish, but more prone to scratching and erosion.


Granite is much harder (Mohs hardness: 6–7), dense, and requires greater cutting power and more durable tools.


Because of these differences, machines must be adjusted in terms of cutting tools, motor power, feed speed, and cooling systems to handle both materials effectively.


 2. Is It Possible to Use One Machine for Both?

Yes, it’s possible, especially if you're using a modern and adaptable machine.


Situations Where One Machine Works Well:

Machines like infrared bridge cutters, CNC machining centers, or 5-axis waterjet cutters are designed to process multiple types of stone.


By changing the blade type (e.g., diamond blades for granite, resin blades for marble) and adjusting operating parameters, you can safely switch between materials.


For polishing and edge profiling, using adjustable-speed grinders and compatible tooling is key.


 When You Should Be Cautious:

Basic or entry-level machines not built for high-hardness materials may not be suitable for granite.


If your project demands extremely high surface precision or mirror finish, specialized machines for each stone may yield better results.


 3. How to Adapt a Machine for Both Marble and Granite

To ensure optimal results when using the same machine for different stones, follow these tips:


Install variable-speed motors to handle varying hardness levels.


Use appropriate blades and tools, and replace them when switching materials.


Set up CNC presets tailored for granite and marble, adjusting cutting depth, speed, and water flow.


Maintain a strong water cooling system, especially critical when cutting dense materials like granite.


 4. Conclusion

Thanks to advancements in stone machinery, it's entirely possible to process both marble and granite with the same machine, as long as it is equipped with the right features and accessories.
