Cleaning

Before conducting thread inspection on rock drilling tools, it is essential to perform cleaning procedures. Ensure that the threaded section of the rock drilling tool is devoid of oil, dust, rust, and other impurities to prevent any impact on the accuracy of test results. Utilize specialized detergent or alcohol for cleaning, followed by wiping it thoroughly with a clean cloth.

Understand thread parameters

Have a thorough understanding of the thread parameters of the rock drilling tool under examination, including specifications and standards. This knowledge is crucial for selecting the appropriate testing methods and tools.

Tool preparation

According to the testing needs, prepare corresponding testing tools and instruments, such as micrometers, microscopes, and limit gauges, and ensure their accuracy and reliability.

Selection of suitable inspection methods

There are many methods for thread inspection, such as visual inspection, tactile inspection, tool inspection, and non-destructive inspection. The appropriate detection method should be selected based on the actual situation, taking into account factors such as accuracy, efficiency, and economy. Visual and tactile inspection may not be sufficient to detect subtle defects in some cases. In such instances, specialized tools or instruments are required for more accurate measurement and assessment. In cases with special requirements or complex situations, a comprehensive evaluation can be achieved by employing multiple detection methods.

Code of practice and safety

During the thread inspection process of rock drilling tools, adhere to the following operational specifications and safety requirements:

  • Observe the operation regulations: test in strict accordance with the relevant operating procedures to avoid damage to tools or injury to personnel due to improper operation.
  • Pay attention to safety matters: during the inspection process, you should pay attention to the safety status of the surrounding environment, ensure that the workplace is clean and orderly, and avoid accidents.
  • Use tools correctly: use testing tools and instruments rationally to avoid tool damage or measurement errors caused by improper use.
  • Protect the object to be measured: during the testing process, it’s crucial to pay attention to protecting the threaded part of the rock drilling tool being tested to prevent damage or harm caused by improper operation.
  • Record data: the data obtained during the inspection process should be recorded and analyzed for comprehensive evaluation and comparison. Recording data also helps to trace problems and improve inspection techniques.
  • Comply with relevant standards and specifications: during thread testing, relevant standards and specifications, such as international standards or industry specifications, should be adhered to ensure the accuracy and reliability of test results.
  • Continuous learning and training: continuously learn and master new inspection techniques and methods and participate in relevant training and exchange activities to improve the inspection techniques level and professional ability.
  • Summarize experience and lessons: during thread inspection, it is crucial to focus on summarizing experiences and lessons, identifying and rectifying existing problems and deficiencies, and consistently enhancing detection efficiency and accuracy.
  • Keep the maintenance and upkeep of testing equipment and tools: regularly calibrate and maintain testing equipment and tools to ensure their accuracy and reliability. Simultaneously, be attentive to the wear and damage of equipment and tools, promptly undertaking repairs or replacements as necessary.
  • Improve teamwork ability: teamwork is crucial in the thread inspection of rock drilling tools. Team members should work closely with each other and coordinate their work to complete inspection tasks and improve work efficiency. Simultaneously, enhance team communication and training to elevate the overall technical expertise and professionalism.

Conclusion

In actual engineering practice, we should pay full attention to the precautions for thread inspection and strictly abide by relevant standards and specifications to ensure the smooth completion of the inspection work.
