Service Description Cylindrical grinding is a precision machining process that involves the use of a rotating abrasive wheel to remove material from the outer surface of a cylindrical workpiece. This process is commonly used to achieve precise dimensions, smooth surface finishes, and tight tolerances on cylindrical components.Surface grinding is a process that involves the use of a rotating abrasive wheel to remove material from the surface of a workpiece to improve the surface finish, achieve precise dimensions, and remove surface imperfections on various types of materials.2 CG Machines- Cylindrical Grinding Machines.3 SG Machines- Surface Grinding Machines.CG Component dimensions- L 1600 mm, OD 250mm.SG Component dimensions- L 850 mm, W 300 mm, H 250 mm.Maximum ID- That can be ground Ø200mm x 150mm Length.
