Structural behavior of the deep hole internal grinding machine structure with artificial granite material.

Tubes, actuators, and aeroplane landing gears are instances of tubular elements with deep holes and thin-wall constructions; such components are the backbone of the aerospace industry. Precision machining of interior holes of cylindrical objects with narrow bores and significant depth to diameter ratios (> 7–8) is more difficult, which highlights the need of grinding such deep holes. In this study, an enhanced construction of the deep hole internal grinding machine is developed and the structural behavior with two different materials cast iron and artificial granite material studied. The internal grinding shaft tool structure is a critical component of this grinding machine, and it is one of the most important variables affecting surface grinding quality due to the structure's length and intricacy, as well as its restrictive outside dimensions. While carrying out the study of machine structure, shaft is also exclusively analyzed with an optimized design. Being the most crucial part of the machine, shaft design was verified through the comparative study of theoretical, simulation analyses, and experimental work. [ABSTRACT FROM AUTHOR]
