Can One CNC Machine Cut Both Marble and Granite?

To​‍​‌‍​‍‌​‍​‌‍​‍‌ survive in the modern stone processing market, efficiency and versatility are the top two factors for fabricators, contractors, stone workshops to be looking for machines that are capable of handling more than one material without losing out on precision or productivity. One of the most common questions asked by potential buyers is: Can a single CNC machine be used to cut both marble and granite?

Simply put, the answer is yes. The machine has to be provided with the right power, structure, tooling, and control technology to be able to cut both materials since marble and granite vary quite a lot in terms of their physical properties. The correct choice of equipment can lead not only to a significant reduction in costs but also to enhanced productivity and easier work. In the article below we will highlight the different stone materials that CNC machines can work on, the problems that fabricators face and also how companies like JingYang are able to help businesses process marble and granite in the most efficient way.

Marble vs. Granite: Know the Difference

Why is it that the processing of marble and granite has to be done under different conditions when cutting in the first place? This is something you have to understand before we delve into CNC machines.

Marble

As a metamorphic rock that consists mostly of calcium carbonate, marble is appreciated for its fine texture, refined look and extensive use in house interior decoration.

Some of the main features of marble are:

• Medium hardness
• Much softer when compared to granite
• Very easy to polish and shape
• Mostly used in decorative works

Since marble is relatively soft compared to other stones, it can most of the time be worked on using less power and will also experience less wear of the tools used.

Granite

Granite is a type of igneous rock that was made when magma cooled down. The presence of quartz and feldspar is what makes granite so hard and durable.

Main features:

• Hardness level is very high
• Very dense
• Great resistance to wear and tear
• Used extensively in both building and outdoor projects

In order to be able to cut granite one would need the use of stronger tools, a machine with a higher power and also one with a structure that is more rigid.

This is the reason why, at first, many fabricators are convinced that they will have to purchase two different machines; one for marble and the other for granite.

Nevertheless, cutting-edge CNC stone machines have made things different.

Mulit-Material Capability: What’s the Reason?

For many companies in the stone processing sector, especially those operating only small and medium-sized workshops, investing in multiple machines might not be the way forward.

Pain Point 1: High Equipment Investment

The acquisition of machinery for stone processing does not come cheap. The purchase of separate machines for marble and granite will involve more capital investment, the need for more factory space and higher maintenance costs.

Pain Point 2: Limited Factory Space

Quite a few fabrication shops do not have a very big workshop area. In such cases the installation of several large machines will result in space constraints very quickly.

Pain Point 3: Operational Complexity

Different machines not only require different training but also different spare parts and maintenance procedures. The management of multiple systems will lead to higher operational complexities.

Pain Point 4: Production Flexibility

Customers put in mixed orders quite often. A shop that does marble countertops in the morning and granite slabs in the afternoon can find switching between machines a real production spoiler.

These reasons have driven a good number of companies to look for a CNC machine that is made available for them to work on both materials without any drawbacks in terms of efficiency and quality.

Cutting Both Marble and Granite by One CNC Machine Only?

Yes, that’s possible. But only if certain features are there on the machine.

A CNC stone cutting machine of a high quality should have the following features:

1. High-Power Spindle or Motor

The force required to cut granite is way more than what is needed for marble. To be sure of a stable cutting performance, the power of the spindle or motor must be sufficient.

2. Heavy-Duty Machine Structure

A lot of vibrations are produced when granite is being cut. To be able to keep precision and stability, a machine frame which is rigid is a must.

3. Advanced CNC Control System

With the help of a modern CNC control system, the operator has the option to change:

• cutting speed
• feed rate
• tool rotation speed
• cooling water flow

With the set of tools provided by the control system, it is possible for the machine to adapt to different stone materials although it is the same machine.

4. Compatible Diamond Tools

Different diamond blades or bits have to be used for different materials, simply to ensure a good service life and cutting performance.

5. Intelligent Cooling System

Granite cutting will generate a lot of heat and dust. Cooling the tool with water is very important for tool protection and improvement of cut quality.

Machines with these sorts of features are capable of processing marble, granite, quartz and other stone materials efficiently.
