TTC HTF-6S 6 Piece Hardness Tester File Set Návod k použití

1. Úvod a produktview

The TTC HTF-6S 6 Piece Hardness Tester File Set provides a convenient and portable method for checking the Rockwell hardness of various materials. This set includes six color-coded files, each designed to test a specific range of Rockwell C (HRC) hardness, from 40 HRC to 65 HRC. It eliminates the need for complex tabletop hardness machines, offering a quick and easy scratch test method suitable for a wide variety of surface materials, including exotic and high-temperature alloys.

2. Nastavení

Upon receiving your TTC Hardness Tester File Set, carefully open the packaging. The set includes six files housed in a protective case, along with an instruction sheet. Ensure all components are present and undamaged.

3. Návod k obsluze

Follow these steps to accurately test the hardness of your material:

1. Připravte si materiál: Ensure the surface of the material to be tested is clean and free from any coatings, rust, or debris that could interfere with the test.
2. Select the Starting File: Begin with the hardest file in the set, which is the Black (65 HRC) file. The files are color-coded for easy identification of their hardness ratings.
3. Perform the Scratch Test: Podržte file firmly and apply moderate pressure. Important: Push the file across the material's surface; do not pull it. Observe whether the file leaves a scratch or mark on the material.
4. Interpret Results and Proceed:
   • Pokud file značky the material, it means the material is měkčí než file's HRC rating. You will then need to try the next softer file.
   • Pokud file sklouzává over the material without marking it, it means the material is těžší než file's HRC rating. In this case, the material's hardness is between the current file's rating and the next harder file you previously tested.
5. Determine Approximate Hardness: Continue testing with progressively softer files until one slips over the material without marking it. The approximate hardness of the material will be between the HRC rating of the file that marked the material and the HRC rating of the file that slipped over it. For example, if the 60 HRC file marks the material, but the 55 HRC file slips, the material's hardness is between 55 HRC and 60 HRC.

The set includes the following files and their corresponding Rockwell C (HRC) hardness:

• Red Handle: 40 HRC
• Yellow Handle: 45 HRC
• Lime Green Handle: 50 HRC
• Green Handle: 55 HRC
• Blue Handle: 60 HRC
• Black Handle: 65 HRC

4. Údržba

To ensure the longevity and accuracy of your hardness tester files:

• Čištění: Po každém použití otřete files clean with a dry cloth to remove any metal particles or debris. Avoid using abrasive cleaners.
• Skladování: Always store the files in their designated slots within the protective case when not in use. This prevents damage to the file tips and keeps them organized.
• Zacházení: Zvládněte files with care. Dropping them or using them improperly can dull the testing edges, affecting accuracy.

5. Řešení problémů

If you encounter issues or inconsistent results:

• Nekonzistentní čtení: Ensure the material surface is clean and smooth. Re-evaluate your testing technique, making sure to apply consistent pressure and use the correct pushing motion.
• Files Not Marking: If even the softest file (40 HRC) does not mark the material, the material's hardness is below 40 HRC. If the hardest file (65 HRC) consistently marks the material, its hardness is below 65 HRC.
• File Mít na sobě: Postupem času se files may wear down, especially if used frequently on very hard materials. If you suspect a file is no longer accurate, it may need replacement.
