The Lathe Machines are an essential part of any mainstream industry that is involved in metal spinning, wood turning and glass making. It is used for performing various operations such as drilling, cutting, knurling, creating tools by rotating on an axis. Lathe Machines are used to make products such as table legs, camshafts or candlestick holders. The machine was basically designed to hold an object into place and rotate it while another tool would be used to cut or shape the held object. The basic version that was used to cut cylindrical metal stock has now been developed to make drilled holes, screw heads, tapered work and crankshafts. The modern Lathe Machines used now a days come with various levels of rotating speeds and the option of manually or automatically move the cutting tool into the workspace.

This material facilitates an easy sliding action. The bed comes in two or more parts which can be bolted together to acquire the desired length of the table. The structure of these beds are heavy and sturdy which is apt for handling the vibrations of the machine while working. The rigid structure holds the machine securely in one place and helps to avoid deflection. The bed comes with guides and ways which helps to support the other parts of the machine. It is designed in such a way so as to bolt it easily on the floor of the workplace.
- The Tool Post
