In summer we had practical training at large machine –building plant. We had heard the plant to be equipped with most modern machinery. We knew of the machinery to be capable of producing huge components for the machine tools to produce machinery. To improve productivity, product quality and working conditions to say nothing of reducing cost, groups of machine tools have been integrated into lines by automatic handling devices. These lines, known as “transfer machines”, are considered to be the most advanced development of modern industrial engineering. Our aim was to watch them perform the machining of various parts to be used for the fabrication of all kinds of machines and machine tools. Among the machinery to be fabricated from parts processed on transfer machines mention may be made of engines, turbines, pumps, huge components, for rolling mills, lathes, forging and pressing machines etc. We know the largest billets being machined to have been supplied from a rolling mill or a forge.
