Hole Finishing

Users’ needs drive development of different reaming systems.

A guide to reaming holes cost-effectively.

Hole finishing: boring vs. circular interpolation.

The production of 'perfect holes' takes patience and careful planning.

People in the aerospace industry expect a lot from reamers. The author, an
engineer who works for a manufacturer of aerospace components, discusses
strategies for job shops interested in developing a precision reaming
program.

Honing was originally a surface finishing operation that did not remove significant amounts of material. This article discusses brush honing, a process the authors say produces results similar to what honing was originally intended to produce. Proper boring is also discussed, because, according to the authors, a properly bored hole will not require further correction through modern aggressive stone honing techniques.

Solid-carbide drills made with advanced submicrograin carbide are capable of producing holes that meet tight specifications without secondary operations. This article explains how these tools produce reamer-like finishes while offering extended tool life and shortened cycle times. An accompanying article discusses coatings for solid-carbide drills.

Superabrasive bore finishing can achieve the same results as conventional honing quicker and at a lower cost. This article describes the types of superabrasive tools available and their uses. The article also explains how to set up and break in the tools.

Superabrasive bore finishing can achieve results in one pass that rival the finishes produced in several passes by other bore sizing operations. This article recounts how a number of shops have used superabrasive tools to finish bores with a higher degree of quality and a lower overall cost per piece.
