The roll industry relies on cutting tools, including turning, milling, and boring tools. These tools are vital in meeting diverse machining requirements during roll processing. This article provides an in-depth analysis of the types of cutting tools, their applications, and suitable material options.
Types of Cutting Tools and Their Applications
1. Turning Tools
Turning tools are primarily used for the external and internal machining of rolls. Examples include external turning tools and internal boring tools. These tools ensure precise machining of the roll's outer diameter and inner holes, delivering high accuracy and excellent surface quality. Turning tools are ideal for tasks that demand superior precision and surface smoothness.
2. Milling Tools
Milling tools are suitable for flat surface machining and slot processing on rolls. They can rapidly remove material, making them ideal for large-scale flat-surface machining and complex slot geometries. Milling tools are particularly effective for machining intricate shapes with high efficiency.
3. Boring Tools
Boring tools are mainly used for internal machining of rolls, especially for deep holes and complex hole shapes. Examples include deep-hole drills and boring tools. These tools ensure the precision and surface quality of holes, making them suitable for applications requiring meticulous internal machining.
Cutting Tool Materials and Their Applications
1. Cemented Carbide Tools
Cemented carbide tools are widely used for roughing and semi-finishing rolls. With their high hardness and excellent wear resistance, these tools are well-suited for medium-load machining tasks, improving productivity while maintaining machining quality.
2. Superhard Tools
Superhard tools, such as PCD (Polycrystalline Diamond) and PCBN (Polycrystalline Cubic Boron Nitride) tools, are designed to finish and superfinish high-hardness materials. These tools offer exceptional hardness and wear resistance, making them ideal for high-load, high-precision machining. They also provide extended tool life and improved machining accuracy.
Conclusion
The roll industry utilizes a wide variety of cutting tools, each playing a critical role in the machining process. Turning tools, milling tools, and boring tools offer unique advantages, and selecting the right material—whether cemented carbide or superhard tools—can significantly enhance machining efficiency and precision. For roll processing, the careful selection of cutting tools and materials is essential for ensuring quality and productivity.
