How to evaluate CBN tool life and its application

CBN tool is a kind of high-performance cutting tool, its life directly affects the machining efficiency and has a significant effect. Currently in use, it is important to ensure high processing efficiency for the life of CBN tools, and the use of reasonable standards for tool life. This article introduces the evaluation method of CBN tool life, and the importance of its application in practice.

Commonly used CBN tool life evaluation method

1. Sword tool polishing inspection method: pass inspection CBN knife tool polishing conditions come and evaluate its lifespan. It is possible to observe the progress of the cutting edge of the tool with a slight mirror or a large diameter, and when the cutting edge changes or appears to be sharply polished, the tool life has been reached.

2. Cutting force measurement method: The tool life will be evaluated as the cutting force changes during the cutting process when the tool is passed through the tool. If the cutting force is excessively set, or if there is an obvious increase in demand, the tool will immediately fail.

3. Surface Roughness Measurement Method: Through measurement processing, the surface roughness of the tool can be evaluated. If the surface roughness of the machined surface is required to be excessive, or if there is a significant change during the initial machining, the tool will be immediately lost.

4. Cutting sound and vibration monitoring method: Sound and vibration signals during the cutting process can be used to evaluate tool life. At the moment, there is an abnormal cutting tone vibration signal.

CBN tool life evaluation importance:

1. Over time replacement tools: CBN tools have a lifespan of 100% certified, which helps companies and time-progress tool replacements, avoiding premature or late replacement tool-induced production efficiency loss or tool waste.

2. Reasonable tool use: pass-through CBN tool life, allowable and reasonable tool use, avoid excessive use or excessive maintenance use of the tool, and measure the service life of the high tool.

3. Increased machining efficiency: CBN tools can be improved and improved, and the quality and efficiency of machining can be guaranteed, avoiding tool failure caused by machining failure and stopping.

4. Retired book: Reasonably rated CBN tool life can be reduced and refurbished.

Application scene

CBN tool life evaluation method is applied to various cutting scenes, special application to the following conditions:

1. Mass production: CBN tooling enterprises frequently use during mass production, the tool life can be shortened after the tool life is stopped.

2. High-difficulty machining: For high-hardness, high-temperature, high-precision and other demanding machining tasks, the CBN tool life can be ensured, ensuring machining quality and efficiency.

3.Recovery processing: shape recovery, high surface requirements processing, CBN tool life can be evaluated and guaranteed cutting effect and quality of work.

Conclusion:

CBN tool life evaluation is a key step that guarantees cutting efficiency and results. Through common evaluation methods, such as tool polishing inspection, cutting force measurement, surface roughness measurement and cutting noise vibration measurement, it is possible to evaluate the CBN tool life and rational use of the tool. In the field of mass production, high-difficulty processing and recovery processing, etc., CBN tool life evaluation has become an important function, high processing efficiency, low-level work, and development of thrust cutting processing.
