Development of Ceramic Cutting Tools for Mechanical Processing

With the ongoing development in the field of processing technology related to the mechanical industry, the demand for improved cutting quality is increasing. The overall performance of the cutting tools is one of the deciding factors that tend to affect the accuracy, processing cost, processing efficiency, and the overall machine surface quality. The technology of high-speed cutting serves to be one of the most effective methods for improving the overall efficiency of processing.

Importance of Ceramic Cutting Tools

The utilization of conventional cutting tools like hard alloy tools or high-speed steel is not known to be capable of cutting top-class engineering materials at higher speeds and higher strengths. However, the advanced range of ceramic materials by leading providers like Ceratizit, are known to mostly compose ionic bonds, mixed bonds, and covalent bonds. Mixed bonds comprising of both ionic bonds & covalent bonds are known to deliver characteristics like higher melting points, higher chemical stability, improved hardness, higher resistance to temperature, oxidation resistance, corrosion resistance, and various other properties.

In addition to this, ceramic materials are also known to deliver the benefit of higher elastic modulus, lower density, improved wear resistance, and improved strength. All of these factors contribute to the rapid development of this material. Presently, ceramic tools are mostly utilized in the field of advanced, high-speed cutting. This is because it helps in delivering top-speed cutting performance that helps in significantly improving the overall product quality and production efficiency.

Top Features Specifying Performance of Ceramic Cutting Tool

In recent times, more researchers are paying attention to ceramic tools due to its higher strength, improved hardness, effective chemical stability, and improved heat resistance. The utilization of ceramic cutting tools can help in reducing the overall machining cost while improving production efficiency & product quality.

Improved Wear Resistance and High Hardness: One of the most notable features of ceramic cutting tools include wear resistance and higher hardness. The hardness offered by ceramic tools made out of silicon nitride is around 94HRC. This is better in comparison to that of carbide cutting tools. The silicon nitride-based ceramic tools can help in processing materials of higher hardness that are difficult to be processed by conventional cutting tools.

This helps in saving the resource and annealing the process. Under similar cutting conditions, the wear & tear of the ceramic cutting tool of silicon nitride turns out to be just 1/15th of other carbide cutting tools. This helps in improving the overall cutting ability.

Amazing Impact Resistance: In addition to cutting the materials of higher hardness with an amazing speed, ceramic tools are also capable of implementing other processing with improved impacts –like milling.

Improved Heat Resistance & Oxidation Resistance in Higher Temperatures: In higher temperature conditions of around 1350 Degree Celsius, ceramic-based cutting tools are still capable of maintaining a higher degree of strength and hardness for continuous cutting.

Make the most of the advanced range of ceramic cutting tools for improved performance.
