Burnishers
Definition
Basic concept of honing machines
Burnishing machines are machine tools used to improve the surface and dimensional quality of metal parts through a process known as burnishing. This process consists of passing a rotating or rotating abrasive tool over the interior or exterior surface of a part to achieve a very fine finish, with high precision and minimal roughness.
Honing is a final or intermediate step in the manufacturing of components that require tight tolerances and optimal surface finishes, such as engine cylinders, precision bores, and hydraulic parts. Burnishers can be manual or automatic, and are specially designed to improve geometry and eliminate surface imperfections.
Types of burnishers
Interior honing machines
Internal honing machines are designed to work internal surfaces of hollow or perforated parts, such as cylinders, tubes or engine blocks. They use abrasive tools mounted on shafts that penetrate into the bore to grind and polish the interior surface.
These machines are essential in the manufacture of hydraulic and engine components, where the internal finish is critical for the correct functioning and longevity of the parts. They can be manual, semi-automatic or CNC, depending on the level of precision and automation required.
Exterior burnishers
External honing machines are intended for working external surfaces of cylindrical or prismatic parts. The abrasive tool acts on the outer surface to improve its finish and dimensionality, eliminating small irregularities and achieving better roughness.
These machines are used in the manufacture of axles, connecting rods, and other parts that require a high quality surface finish. They can be operated manually or through automatic CNC controlled systems to obtain repetitive and precise results.
