The number of knives, or teeth, used on cutting discs can vary depending on the application and the type of material being cut. Here are some reasons why the number of knives may differ:
Material hardness: Harder materials like metals and ceramics require fewer teeth on the cutting disc to ensure efficient and smooth cutting. This is because the teeth need to generate more force to cut through hard materials, and having fewer teeth allows each tooth to cut more effectively.
Material thickness: Thicker materials require fewer teeth on the cutting discs because the teeth need to penetrate deeper into the material to make a cut. This requires more force and energy, and having fewer teeth helps to ensure that the cutting disc can generate enough force to cut through the material.
Cutting speed: The number of teeth on a cutting disc can also affect the cutting speed. More teeth on the disc will result in a slower cutting speed, while fewer teeth will result in a faster cutting speed. The cutting speed is an essential factor to consider when choosing the appropriate cutting disc for a specific application.
Finish quality: The number of teeth on a cutting disc can also affect the quality of the cut. More teeth on the disc will result in a smoother finish, while fewer teeth will result in a rougher finish. This is an important consideration when cutting materials that require a high-quality finish.
Overall, the number of teeth on a cutting disc is an important factor to consider when choosing the appropriate disc for a specific application. It is essential to select the right number of teeth to ensure efficient and safe cutting while achieving the desired finish quality.
