Honing (metalworking) - Wikipedia

Honing is an abrasive machining process that produces a precision surface on a metal workpiece by scrub an abrasive grinding stone or grinding wheel against it along a controlled path. Honing is primarily used to improve the geometric form of a surface, but can also improve the surface finish.. Typical applications are the finishing of cylinders for internal combustion engines, air bearing

Service life of machined brittle material and particularly glass workpieces, used in technology fields such as civil engineering, transports or optics, could be shortened by local irregularities. Indeed, grooves or sub-surface damage (SSD) can lead to cracks and fracture in operation [1,2]. Therefore, manufacturers tend to smoothen the surface finish by achieving a long and costly polishing

Is Grinding Improving or Worsening the Surface Finish?

A high Ra means a rougher workpiece surface finish; a low Ra means a smoother surface. The typical way to measure surface roughness is with a profilometer. The instrument has a stylus that moves across the workpiece perpendicularly to the grinding scratches and traces the profile.

Surface finish - Wikipedia

Surface finish, also known as surface texture or surface topography, is the nature of a surface as defined by the three characteristics of lay, surface roughness, and waviness.[1] It comprises the small, local deviations of a surface from the perfectly flat ideal (a true plane). Surface texture is one of the important factors that control
