Lathe Machine

Introduction

Lathe Machine is the most oldest machine gear known to mankind. Its first used in 1300 BC in Egypt. The primary machine was Lathe which is presently called a two-man machine. In this one individual would turn the wood workpiece using rope and the other individual would shape the workpiece using a sharp tool. This plan was further improved by the Ancient Romans who added the turning bow and lather the paddle (as there in the sewing machine) was added.

1950 mechanism

Further during the modern revolution Engines and water wheel were connected to the Lathe to turn the workpiece to a higher speed which made the work quicker and simpler. Then, at that point, In 1950 servo mechanism was used to control the machine. From this rough asking and over a time of over two centuries, the advanced motor machine has developed.
Presently we have the most exceptional type of the Lathe which is the CNC Lathe. HENRY MAUDSLAY, a British Engineer is considered as the innovator of a lathe machine.
