Marble slabs and marble platforms are made from diabase, gabbro, igneous rock, or other rocks with equivalent properties that have been buried deep underground for millions of years, featuring fine grains, uniform structure, high hardness, wear resistance, and easy processability. After mechanical cutting and milling, they are meticulously hand-polished by our technicians. These products exhibit a uniform structure, fine grains, high hardness, excellent wear resistance, high precision, stability, non-magnetic properties, no plastic deformation, rust resistance, easy cleaning, and convenient maintenance.

After prolonged use, the working surface of marble slabs and marble platforms may wear down due to friction and impact with workpieces. When the wear exceeds a certain level, the flatness accuracy will deviate beyond acceptable limits. Continued use under such conditions will affect the accuracy of measurement results. At this point, the marble slab or platform requires grinding maintenance and repair. Our technicians use grinding methods to restore the flatness of the marble slab or platform to meet the corresponding grade requirements and satisfy the production needs of manufacturers.

Botou Linuo Tools and Measuring Instruments Co., Ltd. offers marble slab repair, marble platform repair, granite slab repair, granite platform grinding repair, grinding maintenance, and accuracy restoration services. Our technicians are dispatched to the user's site for on-site repairs, ensuring quick and efficient service at reasonable prices. Payment is only required after the repair has been completed and passed third-party inspection. Manufacturers with such needs are welcome to contact us! The flatness calculation formulas for marble slabs and marble platforms after repair are as follows:

Flatness tolerance calculation formula for marble platforms after repair (according to GB/T20428-2006 standard):

Grade 0 marble slab (marble platform) flatness tolerance (micrometers) = 0.003 multiplied by the diagonal length of the marble slab (marble platform) (mm) + 2.5;

Grade 1 marble slab (marble platform) flatness tolerance (micrometers) = 0.006 multiplied by the diagonal length of the marble slab (marble platform) (mm) + 5;

Grade 2 marble slab (marble platform) flatness tolerance (micrometers) = 0.012 multiplied by the diagonal length of the marble slab (marble platform) (mm) + 10;

Grade 3 marble slab (marble platform) flatness tolerance (micrometers) = 0.024 multiplied by the diagonal length of the marble slab (marble platform) (mm) + 20.
