Handground Flat PlatesThe processing involves further grinding on the basis of刮研平板, with its precision _, and effect _, which essentially means scraping the flat surface evenly and ensuring _ flatness accuracy. Then, the three flat plates are divided into groups of 1, 2, and 3, sequentially as 1-grind-2, 2-grind-3, and 1-grind-3. The three plates are initially ground using coarse sand in a cyclic manner, while also being checked with a blade gauge. The coarse sand is used to flatten the knife patterns on the three plates and ensure consistent post-grinding precision, followed by fine sand grinding to achieve a smoother and more detailed surface finish.

Standard specifications for hand-ground flat plates100×150, 100×200, 200×200, 200×300, 300×300, 300×400, 400×400, 400×500, 400×600, 500×500, 500×600, 500×800, 600×800, etc. Small hand-operated grinding plates are in stock; large plate grinding requires customization.

 Handcrafted Grinding Plate Characteristics：

Operation simple, quick sanding, ample embedded sand amount, easy to apply the same type of sand after use, with significant improvement in luster after polishing.

2. Achieves high smoothness and fit for the blocks, resulting in mirror-like brightness on the workpiece surface.

Grinding Plate ApplicationsManufacturing and repair of measuring tools, workpiece grinding, high-precision mechanical parts production, and optical instrument processing.
