Similarities and differences between drilling, boring and reaming are discussed here in table form. Basically, drilling is a process that originates a hole; while, boring enlarges the hole diameter. Reaming and honing are used to smoothen hole surfaces. Drilling must be carried out prior to boring or reaming

First, it is a stock removal process ( vertical honing machine) which takes out ruptured metal and reaches base metal. Second, a finish pattern is generated to provide the best possible surface for promoting optimum lubricating conditions. Third, honing stones assures extremely accurate straightness, roundness and size of the cylindrical surface.

The grinding process is truly a chip producing machining process. The rough surface of the abrasive wheel spreads into small portions of the workpiece as required. It is also known as a grinder. The grinding process is capable of producing very accurate sizes, equally accurate geometry like flatness or circle and extremely good surface finish.

Cutting Tool Applications, Chapter 18: Lapping and Honing. June 29, 2020. Lapping is a final abrasive finishing operation that produces extreme dimensional accuracy, corrects minor imperfections, refines surface finish and produces a close fit between mating surfaces. Honing is a low-velocity abrading process. George Schneider.

Ball burnishing, burnishing balls, or ballizing, is a replacement for other bore finishing operations such as grinding, honing, or polishing. A ballizing tool consists of one or more over-sized balls that are pushed through a hole. The tool is similar to a broach, but instead of cutting away material, it plows it out of the way.

Centerless grinding operation: This type of grinding operation, two grinding wheels are fitted parallel with a 5-10-degree angle which is provided to obtain a longitudinal motion of the workpiece. A cylinder rod is placed between the two-grinding wheel due to the tilted angle. This allows the workpiece to automatically pass through the wheels ...

A larger abrasive grinding wheel; The beauty of centerless grinding is that the workpiece is held in place by the pressure of the rotating wheels. No fixturing is required, so the setup is simple and turnaround times are fast. And because the workpiece is rigidly supported, there is no deflection during the grinding operation.

Boring is a cutting process that involves the use of a single-point cutting tool or boring head to enlarge an existing hole in a workpiece. This is in stark contrast to drilling, which is performed to create an initial hole in a workpiece. Boring processes are typically performed using a lathe, milling machine or a horizontal boring mill.

Honing Operation. To clean metal by removing roughness from its hole or bore made by a honing tool is called honing operation. This operation is conducted in the following two ways: Dry honing; Wet honing #1 Dry Honing. Jobs which requires rough finishing or from which more extra metal is to be removed, are given dry honing treatment.
