SGU-35N, Universal Cylindrical Grinding Machine
Cylindrical grinding is a precision machining process used to finish the external or internal surfaces of cylindrical components such as shafts, bearing parts, and precision mechanical components. During the grinding process, the workpiece rotates while a grinding wheel removes microscopic layers of material, enabling tight dimensional tolerances and consistent surface quality.
Because of its ability to achieve high dimensional accuracy, excellent roundness, and superior surface finish, cylindrical grinding is widely used in industries such as automotive, aerospace, bearing manufacturing, and industrial machinery.
