basic information
Large flat surface grinding processing is used for the surface finishing of products that require flatness, surface roughness, and straightness, such as large and long coating dies (slit dies/T-dies/slot dies) used in die coating. The surfaces of workpieces measuring several meters are processed with micron-level flatness and surface roughness. As the workpieces become larger and longer, the level of processing required to achieve flatness, straightness, and parallelism significantly increases. Toray Precision possesses high-precision surface grinding machines and utilizes years of processing know-how to achieve high-precision machining.
