Maintenance and Storage of PCBN and PCD Tool Inserts

Introduction: In the tooling industry, the longevity and performance of cutting tools are pivotal. Polycrystalline Cubic Boron Nitride (PCBN) and Polycrystalline Diamond (PCD) tool inserts represent significant investments in precision machining. Proper maintenance and storage are essential to ensure their longevity and performance. This article outlines the best practices for maintaining and storing PCBN and PCD tool inserts.

Understanding the Sensitivity of PCD and PCBN Inserts: PCBN and PCD inserts, although extremely hard, can be sensitive to mishandling. Environmental factors, improper handling, and storage can lead to premature wear or even damage. Understanding this sensitivity is the first step in implementing effective maintenance and storage protocols.

Cleaning and Inspection: Regular cleaning and inspection are crucial. After use, tool inserts should be cleaned with appropriate solutions to remove any residual materials. A visual inspection for any wear or damage should be carried out before storing the inserts.

Appropriate Storage Solutions: Tool inserts should be stored in a dry, temperature-controlled environment to prevent oxidation and degradation. Individual packaging or protective casings are recommended to avoid physical damage from contact with other tools or surfaces.

Handling Practices to Extend Tool Life: Careful handling is essential to avoid chipping or breaking the inserts. Use appropriate tools and techniques when mounting or removing inserts from machinery, and always handle them with protective gloves to avoid contamination from oils or moisture.

Record-Keeping for Maintenance Schedules: Maintaining records of usage and maintenance schedules helps in predicting wear patterns and planning for replacements. This proactive approach ensures that machining processes are not interrupted due to unexpected tool failures.

Conclusion: The efficiency and quality of machining operations significantly rely on the condition of cutting tools. By adhering to proper maintenance and storage practices, the functional life of PCBN and PCD tool inserts can be extended, ensuring consistent performance and cost-effectiveness. A little care goes a long way in safeguarding your investment in these premium tooling solutions.
