Correctly selecting and using polycrystalline diamond (PCD) saw blades is crucial for ensuring work efficiency and safety. Below are the key considerations when selecting and using PCD saw blades.

Selection:

1. Blade Type:
   Choose the appropriate type of PCD saw blade based on specific cutting requirements, including straight tooth type, trapezoidal tooth type, and flying knife type. Different types are suited for different materials and cutting methods.

2. Specifications and Size:
   Select the correct specifications and size of the PCD saw blade according to the thickness of the material to be cut and the work requirements. Ensure the blade is capable of completing the required cutting tasks.

3. Quality Certification:
   Opt for brands and products with quality certifications to ensure the blade's reliability, good wear resistance, and long service life.

Usage:

1. Installation:
   Follow the installation instructions carefully to ensure the blade is installed securely and does not become loose during use.

2. Cutting Parameters:
   Set appropriate cutting parameters based on the hardness and thickness of the material being cut, such as rotation speed and feed rate. Both excessively high and low parameters can negatively impact cutting performance and blade lifespan.

3. Cutting Posture:
   A correct cutting posture ensures smooth cutting and high-quality cutting edges. Pay attention to the feeding angle and pressure of the blade to avoid excessive speed or slow cutting, which could lead to blade wear or dangerous situations.

4. Safety Protection:
   When using a PCD saw blade, it is essential to wear appropriate safety gear, such as safety goggles, protective gloves, and a dust mask, to avoid injury from debris and dust generated during cutting.

In conclusion, when selecting and using PCD saw blades, it is important to consider factors such as blade type, specifications and size, and quality certification. During use, ensure proper installation, cutting parameters, cutting posture, and safety protection to achieve excellent cutting results and ensure personal safety.
