Surface grinding. Surface grinding is done on flat surfaces to produce a smooth finish. It is a widely used abrasive machining process in which a spinning wheel covered in rough particles (grinding wheel) cuts chips of metallic or nonmetallic substance from a workpiece, making a face of it flat or smooth. Sometimes a surface grinder is known as ...
Surface finishing. A drill bit with surface finishing to make the cutting edges harder. Surface finishing is a broad range of industrial processes that alter the surface of a manufactured item to achieve a certain property. [1] Finishing processes may be employed to: improve appearance, adhesion or wettability, solderability, corrosion ...
Abrasive machining. Abrasive machining is a machining process where material is removed from a workpiece using a multitude of small abrasive particles. Common examples include grinding, honing, and polishing. Abrasive processes are usually expensive, but capable of tighter tolerances and better surface finish than other machining processes.
Honing is an abrasive machining process that produces a precision surface on a metal workpiece by scrubbing 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 ...
Lapping. Lapping machine. Lapping is a machining process in which two surfaces are rubbed together with an abrasive between them, by hand movement or using a machine. Lapping often follows other subtractive processes with more aggressive material removal as a first step, such as milling and/or grinding. Lapping can take two forms.
A flat workpiece surface is processed, hence the word flat; the word honing is used because the cutting speed is low compared to grinding. A fixed abrasive is used to provide accuracy and optical appearance of the surface finish. Sometimes it is also called fine grinding or surface grinding using planetary kinematics.
Grinding is a subset of cutting, as grinding is a true metal-cutting process. Each grain of abrasive functions as a microscopic single-point cutting edge (although of high negative rake angle), and shears a tiny chip that is analogous to what would conventionally be called a "cut" chip (turning, milling, drilling, tapping, etc.) [citation needed].
Abrasive flow machining. Abrasive flow machining (AFM), also known as abrasive flow deburring[1] or extrude honing, [2] is an interior surface finishing process characterized by flowing an abrasive -laden fluid through a workpiece. [1][3][2] This fluid is typically very viscous, having the consistency of putty, [2][3] or dough. [1]
