It boasts low cost and high cutting efficiency.

-Disadvantages:

In comparison to diamond cutting discs, silicon carbide cutting discs exhibit slightly reduced cutting accuracy and surface finish post-cutting.

-Applicable scene:

It is applicable to the demand for large-scale cutting in industrial production.

(3) Laser cutting

Laser cutting involves the non-contact cutting of quartz plates and is carried out using high-energy laser beams.

-Advantages:

It features extremely high cutting accuracy, no mechanical stress, and is suitable for cutting quartz plates of complex shapes.

-Disadvantages:

The equipment cost is high and the cutting speed is relatively slow.

-Applicable scene:

It is suitable for occasions with high-precision and complex-shaped cutting requirements.

(4) Water cutting

Water cutting is carried out using high-pressure water flow or mixed abrasives.

-Advantages:

It is characterized by an absence of heat-affected zones and a high-quality cutting surface.

-Disadvantages:

The equipment cost is relatively high and the cutting efficiency is low.

-Applicable scene:

It is suitable for cutting heat-sensitive quartz plates.

3. Precautions in practical application

(1) Tool maintenance

Regularly inspect and maintain the cutting tools to ensure their stable performance.

(2) Coolant usage

During mechanical cutting, the use of coolant can reduce thermal stress and tool wear.

(3) Operation specification

Cut strictly in accordance with the operation specifications to avoid tool damage or safety accidents caused by improper operation.

4. Conclusion

In the processing of quartz plates, the selection of cutting tools requires a comprehensive evaluation of factors such as cutting requirements, tool types, and associated costs. Diamond cutting discs are particularly suitable for high-precision applications, while silicon carbide cutting discs are more appropriate for mass production. Laser cutting and water jet cutting offer distinct advantages in achieving high precision and handling complex-shaped cuts. In practical applications, attention must also be given to tool maintenance, proper coolant usage, and adherence to operational standards in order to ensure both processing quality and workplace safety. By selecting cutting tools rationally, the efficiency and quality of quartz plates processing can be significantly enhanced, thereby meeting the diverse demands of various application scenarios.
