basic information
Large flat surface grinding 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 (work objects) on the scale of several meters are processed with micron-level flatness and surface roughness. As the size and length of the workpieces increase, the level of processing required to achieve flatness, straightness, and parallelism significantly rises. Toray Precision possesses high-precision flat grinding machines and utilizes years of processing know-how to achieve high-precision machining.
