MACHINING ACCURATE HOLES WITH REQUIRED ROUGHNESS

Abstract

The knowledge gained from the theoretical and practical tests in the production of precise openings has been utilized in a wide range of technologies from simple machine parts to complex schemes requiring accurate placement of individual parts. The topic here deals with the production of precise holes of required roughness according to the customer's requirements, it is a sealing of hydraulic cubes with a ball plug. The article examines the possibilities of existing technology, proposes the possibilities of using other tools or changes in the machining parameters, all using one machine tool. All theoretical knowledge has been verified by practical tests with the use of measuring instruments such as hardness meters. All output measurements were recorded in tables and graphs for more clear results and used in practice.
