Feasibility Study for an Electrochemical Grinding (ECG) Machine for Large Diameter Workpieces.
Abstract:
The objective was to conduct a feasibility study for an Electrochemical grinding machine that would include Electrochemical Grinding ECG, Creep Feed and Conventional Abrasive Grinding. The machine would be a rotary type grinder with capacity to grind 14-foot diameter workpieces, particularly roller bearing paths for gun mount stands. The conventional grinders, production processes and methods currently used at NOSL for roller paths were reviewed in detail. An in-depth analysis was made of the results expected of a theoretical ECG grinding machine, from both a design and a production viewpoint. Samples were ground on an ECG surface grinder to confirm theoretical hypothesis with regard to grinding rates, table speeds, etc. It was concluded that ECG for roller path production is not practicable and effective at this time.
