Retrofitting of the hydraulic installation of a CNC lathe for re-profiling railway wheelset
Journal Title: Proceedings in Manufacturing Systems - Year 2017, Vol 12, Issue 2
Abstract
On the occasion of refabrication of a specialized parallel lathe, designed for the processing of railway wheels (whellset), the authors of this article designed and built a new hydraulic installation. This new installation correlates with the new working method of the machine tool. Initially, the lathe, fitted with two main shafts that work "in the mirror", realized the specific profile of these wheels by copying. After refabrication, the machine tool works in with CNC. After the realization of the hydraulic project, the simulation of the dynamical operation of the lifting/lowering system of the blank/workpie was performed. The lifting/lowering system works with inertial masses up to 2000 kg, requiring positioning precision and repeatability. Due to the large weight of the semifinished, but also due to the precision requirements specific to the CNC machine tools, it is imperative that the clamping and locking systems to be very firm and secure.
