Granite platforms play a vital role in precision measurement and inspection. Their stability and accuracy directly impact the reliability of test results. To ensure long-term platform performance, careful attention must be paid to certain details during operation and maintenance.
During daily cleaning, avoid using excessive moisture. Typically, wipe the work surface with a slightly damp cloth and mild detergent, then dry with a clean, soft cloth. Oil stains can be removed with ethanol, acetone, or a specialized cleaning agent. Because granite is a brittle material and sensitive to impact, avoid striking the work surface with iron or heavy objects to prevent dents and affect inspection accuracy. Minor scratches on the platform surface can be repaired with specialized cleaning and care products; however, more severe wear requires professional technicians to restore the surface to its original accuracy. Painted platforms can be cleaned with a suitable paint stripper, strictly following the instructions.
In addition to ensuring routine maintenance of granite platforms, checking their flatness is also a key step. Common methods include the gap method and the indicator method. The indicator method is commonly used by granite and marble tool manufacturers, as these companies have the ability to manufacture their own testing platforms and supporting equipment.
The indicator method typically requires a testing device equipped with a dial or micrometer indicator. Before testing, the platform must first be leveled to ensure measurement accuracy. Measuring points are then placed on the platform's reference surface. The measuring device is moved to read the needle movement point by point, recording the deviation at each location relative to the reference surface. This method provides a direct indication of flatness error and is suitable for testing small and medium-sized platforms. For extra-large platforms, such as those measuring 2000 x 2000 mm or larger, more advanced equipment, such as a coordinate measuring machine, is required to obtain more reliable results.
With the increasing demand for testing accuracy in the precision manufacturing industry, the proper use and scientific testing of granite platforms are becoming increasingly important. Proper operation and maintenance can maximize the platform's service life and ensure measurement stability over the long term.
