Yes, the Core Trimmer and Cut-Off Machine – NG-CoreTrim can machine longer rock cores by simply turning the sample upside down in the device. This feature makes the machine highly versatile, allowing it to handle rock cores that exceed the standard size range it holds. By repositioning the sample, users can be certain that the entire core length is trimmed or cut evenly, resulting in well-prepared specimens for testing.

This flexibility is particularly useful in rock testing laboratories where core samples may vary significantly in length. The ability to machine longer cores without compromising precision allows even irregular or oversized samples to be shaped and prepared for further rock mechanics analysis. Thus, the NG-CoreTrim provides laboratories that work with a variety of rock samples with both adaptability and accuracy.

The Core Trimmer and Cut-Off Machine – NG-CoreTrim is equipped with a proper vice that is intended to securely hold irregular rock pieces in place during trimming or cutting operations. This vice can handle samples up to approximately 7x14 cm so that even unevenly shaped or oversized samples are firmly secured throughout the machining process. It is important to have a vice that provides stability so that precise and consistent cuts or trimming can be accomplished.

By firmly holding irregular rock pieces, the NG-CoreTrim guarantees that the sample remains in position, preventing movement that could lead to inaccurate cuts or potential safety hazards. This feature is particularly useful for laboratories that frequently deal with non-standard rock samples. Every sample will be handled with precision and safety thanks to the vice system, whether it is trimming or cutting rock cores.

The Core Trimmer and Cut-Off Machine – NG-CoreTrim is equipped with a number of safety features to guarantee operator protection during use. One key feature is the cooling water inlet, which helps to cool the cutting blade or cup wheel during the trimming or cutting process. This prevents overheating and provides smooth, safe operation, especially when working with hard rock materials.

Additionally, the machine includes a transparent cover that conforms to CE safety requirements. This cover not only provides visibility but also acts as a protective barrier to shield the user from debris or accidental contact with the moving parts. A built-in safety switch automatically stops the machine if the cover is opened during operation, thus increasing safety and preventing accidents.

The Core Trimmer and Cut-Off Machine – NG-CoreTrim can be fitted with two types of cutting tools depending on the specific task at hand. It supports either a cutting blade or a double-faced cup wheel. The cutting blade is ideal for precise cuts of irregular rock samples, allowing users to obtain well-shaped cubes, prisms, or other rock forms. This tool is particularly useful when accuracy and smooth cuts are required.

On the other hand, the double-faced cup wheel is used for surfacing cylindrical specimen ends. This provides assurance that the ends of the cores are flat and smooth, which is imperative for preparing rock samples for further testing. The flexibility to switch between these two tools enhances the machine’s versatility, allowing it to be used for an extensive range of sample preparation tasks in rock mechanics laboratories.
