Engineering Workshop Practice – The Lathe Machine Operations - Boring

Boring is one of the basic operation we use the lathe machine for. Boring is necessary in many cases to produce accurate holes. Drilled holes are seldom straight due to imperfections in the material which cause drills to move out of alignment. Therefore, where accuracy is important, drilled holes are usually made undersize and then bored or reamed to the proper dimensions. Boring is also useful in truing large holes in flat material. In this case, the hole is cut undersize using a bandsaw or trepanning tool and is trued to proper dimensions by boring. What does the boring operation involves?

Engineering Workshop Practice – The Lathe Machine Operations - Drilling 2

The lathe machine is famed for its numerous workshop uses, which include the drilling operation. The lathe can perform this task of drilling owing to the alignment between its headstock and tail-stock. This perfect alignment enables you to drill holes that are precisely centered in a cylindrical piece of stock. This article discusses on step by step drilling operation using the lathe and the intricacies.

Engineering Workshop Practice - Lathe Machine Operation - Drilling

Although the lathe is not a drilling machine, but frequently, holes will need to be drilled on work piece before other internal operations can be completed, such as boring, reaming, and tapping. Thus, time and effort are saved by using the lathe for drilling operations instead of changing the work to another machine.

In this article, we shall be discussing the following

Enginnering Workshop Practice - The Engine Lathe - Parts, Accessories And Maintenance

There are different types of lathes installed in the machine shops in various industries. These include the engine lathe, the horizontal turret lathe, and several variations of the basic engine lathe, such as bench, toolroom, and gap lathes. All lathes, except the vertical turret type, have one thing in common. For all usual machining operations, the workpiece is held and rotated about a horizontal axis, while being formed to size and shape by a cutting tool. In the vertical turret lathe, the workpiece is rotated about a vertical axis. Of the various types of lathes, the type you are most likely to use is the engine lathe. Therefore, this chapter deals only with engine lathes and the machining operations you may have to perform.
