Grinding process removes burrs and sharp edges from cast iron workpieces. It smooths casting surfaces to prepare parts for coating and improve finish quality of municipal outdoor products.
Grinding is a surface finishing operation after casting. Workers carefully grind the cast iron workpiece to remove casting burrs, sharp edges and surface imperfections.
Smooth grinding eliminates rough spots and ensures clean, uniform surfaces for park bench components. This step prepares the cast parts for subsequent surface treatment like electrophoresis or powder coating, helping coating adhere better and improving the final appearance and anti-corrosion quality of municipal metal products.
