What you meant by superfinishing operation?
Superfinishing is a process in which a rotating workpiece is finished by a relatively soft stone with fine abrasive oscillating parallel to the workpiece surface. The stone typically oscillates at an amplitude of 1–4 mm and a frequency of 10–50 Hz, and it contacts the workpiece at light pressure, typically 0.1–0.2 MPa.
What are consists of three phases in superfinishing process?
The superfinishing process consists of three phases: (1) the cutting phase, which is characterized by a high material removal rate due to sharp cutting edges; (2) the transition phase, which is characterized by a decrease in the material removal rate due to dulling and loading of the stone; and (3) the finishing phase …
Which is not super finishing process?
Honing is a finishing process, in which a tool called hone carries out a combined rotary and reciprocating motion while the workpiece does not perform any working motion.
How does superfinishing differ from honing?
During superfinishing, also described as short-stroke honing, a rotary motion is overlapped with a short-stroke oscillating motion. The cutting motion during long-stroke honing consists of a rotary motion and a long-stroke oscillating motion. Honed surfaces show good tribological properties.
What is a finishing process?
Finishing processes aim to alter the surface of a manufactured part in order to achieve a particular characteristic. These processes are either removing/reshaping finishing or adding/altering finishing.
What is the polishing process?
Polishing is the process of creating a smooth and shiny surface by rubbing it or by applying a chemical treatment, leaving a clean surface with a significant specular reflection (still limited by the index of refraction of the material according to the Fresnel equations).
What are the three functional finishing?
Various most common functional finishes are antimicrobial, durable press antistatic, UV protection, flame retardant, self-cleaning, water repellent, soil-resistant, and wrinkle recovery (Tomasino, 1992).
What is difference between polishing and buffing?
Technically polishing refers to processes that use an abrasive that is glued to the work wheel, while buffing uses a loose abrasive applied to the work wheel. Polishing is a more aggressive process while buffing is less harsh, which leads to a smoother, brighter finish.
Whats the difference between polishing and buffing?
Polishing generates a brushed or lined finish, where buffing removes the lines and creates a bright luster finish. The process of buffing generally requires surface refinement polishing prior to buffing.
What do you need to know about microfinishing?
Microfinishing (superfinishing) is the ultimate abrasive process, allowing users to: Remove the amorphous surface layer (thermally damaged) caused by grinding Obtain very consistent surface finishes with predictable and repeatable results Achieve virtually any surface finish – Ra, Rz, Rt, Rpk, Bearing Area
