I. What are the characteristics of waterjet cutting on marble?

Any type of stone can be cut using waterjet technology. Waterjet cutting is one of the most common industrial cutting methods and is suitable for engineered stone, thick granite, marble, and even other non-stone materials such as glass, metal, and plastic.

The waterjet stone cutting machine can easily cut 12-inch stone at high speed. Can cut granite, marble and other similar stones over 12 inches thick. However, greater thickness reduces cutting speed.

1. High precision

Waterjet cutting enables extremely high cutting accuracy, down to several thousandths of an inch. This makes it ideal for marble crafts and decorations that require fine and intricate cutting.

2. Cold cutting

This is a cold cutting process that produces no heat. Since there is no issue with thermal deformation, waterjet cutting can be used to prevent thermal cracks or color changes in marble, maintaining the quality of the cut part.

3. Suitable for various materials

Waterjet cutting is not only suitable for marble, but can also be used to cut metal, ceramics, glass and other hard materials. This multi-material suitability makes it a versatile cutting process.

4. Environmental protection

Waterjet cutting is a relatively environmentally friendly cutting method. It does not produce toxic gases and does not require the use of harmful chemicals.

5. No secondary processing required

Since no thermal deformation is caused during the cutting process, secondary processing is usually not required. This reduces material waste and the need for subsequent processes.

6. Flexibility

Waterjet cutting can easily cut straight lines, curves, holes and other shapes to meet different design and engineering needs. This flexibility makes it widely used in custom projects.

7. Fast cutting speed

Waterjet cutting’s cutting speed is relatively fast, which can improve production efficiency.

8. A small amount of waste

Due to its high precision and controllability, waterjet cutting generates relatively little scrap, reducing material waste.

9. Low noise level

Waterjet cutting generally produces lower noise levels than some other cutting methods, helping to improve the work environment.

The application range of waterjet cutting in marble cutting includes making decorative panels, sculptures, architectural decoration and other fields. The advantages of this technology make marble cutting more precise and efficient.

II. Comparison of stone cutting methods

Waterjet excels at cutting and beveling ultra-hard stone that would be difficult to cut with a traditional saw.

Waterjet technology cuts the hardest materials of almost any thickness by using ultra-high-pressure water flow mixed with abrasives without generating heat or distortion:
Thick granite, marble, slate, limestone, soapstone, travertine, artificial stone any other materials used for floors and counters.

Waterjet technology is the most effective solution for cutting and beveling stone as it increases material yield and operating efficiency and reduces costs compared to traditional equipment such as saws.

Did you know that most interior designers who create intricate patterns and inlays in hotels on the Las Vegas Strip prefer waterjet? This is because you also get accurate lines and details.

III. Get the right waterjet for your stone cutting needs

Choosing the right waterjet cutting equipment can be challenging because this is such a vast market. Many manufacturers throw out a lot of technical jargon to try and make their products look the best.

However, choosing the most suitable waterjet cutting machine should depend on your specific requirements. Here are some factors you should consider:

1. Budget

Outline your budget for a waterjet cutting machine. More features come at a higher price, so thinking about your budget can help you choose a device you can afford and features you want to ignore.

2. Water jet pressure

The performance of a water jet cutting machine is directly related to the pressure of the water jet. High-pressure water jets are generally capable of handling harder materials and greater depths of cut.

The water pressure of a waterjet cutting machine can have a significant impact on the price. If you want to cut medium-thick stones, a medium-pressure pump will suffice. You will need a more versatile UHP machine to handle the thickest materials.

3. Cutting shaft

The higher number of cutting axes on a waterjet cutting machine allows for the processing of more complex cutting shapes. 5-axis tooling can create any complex design you desire.

4. New functions

Some users may seek specific features of waterjet cutting. For example, cutting stone underwater may be essential for those who want negligible noise during cutting operations.

5. Cutting materials

Determine the type of material you primarily need to cut, including the texture and thickness. Different waterjet cutting machines may be suitable for different kinds of materials.

6. Cutting size

Consider the range of sizes you typically need to cut. Different models of waterjet cutting machines may have different cutting size limitations.

7. Cutting accuracy

If you need high-precision cutting, then you need to choose a waterjet cutting machine with a high-precision control system. Some applications, such as art production or aerospace parts, may require extremely high precision.

8. Cutting speed

Is cutting speed critical to your application? Some waterjet cutting machines may offer higher cutting speeds, suitable for high-volume production.

9. Degree of automation

Consider the level of automation for your waterjet cutting machine. Some machines have automated features, such as automatic tool replacement, cutter head height adjustment, etc., which can improve production efficiency.

10. Maintenance and consumable costs

Consider the maintenance costs of the equipment as well as the price of consumables such as waterjet cutting heads. Some models may have lower maintenance requirements and more economical supplies.

11. Manufacturer reputation

Choose equipment from well-known manufacturers who have a good reputation in the industry and provide reliable technical support and after-sales service.

12. Training and support
