Introduction to the Lathe as a Milling Machine

The lathe Is by far the most versatile of all machine tools. Though developed as a producer of “solids of revolution”. working between centres, the introduction of the headstock  – a  very  long time  ago  – rendered the production of flat surfaces possible and “surfacing” techniques are mentioned in almost every written record of  the lathe. When  turning  became  a leisure occupation – about 400 years ago so far as we know – the wish to apply decoration to plain turned work resulted in the development of a number of auxiliary devices. Some, like the “Rose Engine”, were effectively a different…

Correct Overhauling Procedure of Lathe Machine

Careful maintenance will increase the life and efficiency of the machine. A thorough cleaning is very much necessary for any machine in continuous use. It requires checking and adhering to the lubricating instructions from time to time and any defect however small it is, should be immediately rectified, otherwise this will lead to major breakdown of the machine. This will result in the loss of production and high cost of repair. To overcome the difficulties of loss of production and high cost of repair of machines, it is essential to overall the machine within specified time. During the life of…
