Honing Bore Tubes and Smooth Bore Cylinder Tubing
We are a professional manufacturer of Grinding Steel Tubes, specialising in the production of high quality Grinding Steel Tubes, also known as “Grinding Bore Steel Tubes” or “Grinding Casing”.
Ground bore steel tubes that have been precision machined and ground are often referred to as ground tubes, bright tubes, or ground bore tubes. The production process of ground tubes involves cutting the diameter and surface roughness of the bore by rotating a grinding tool to achieve a highly accurate, smooth and consistent internal surface.
