Frequently Asked Questions
They are primarily used to support cylindrical components such as shafts, tubes, and sleeves, ensuring they remain parallel to the working surface for inspection, clamping, and precision machining.
Ground finishes offer a very smooth surface, while hand-scraping creates microscopic peaks and valleys that help retain lubrication and prevent the workpiece from "seizing" or sticking to the block.
For high-tolerance applications, we recommend Precision Grade 1, which offers the tightest tolerances and highest accuracy according to the JB/T8047-95 standard.
We apply a combination of pickling oil, plastic lining, and professional anti-corrosion painting to ensure the tool arrives in perfect condition regardless of sea humidity.
