How Horizontal Boring Mills Work And Their Functional Parts


When the job is to bore large holes on heavy workpieces such as engines and frames and similar applications where lathes and drill machines are not possible, boring milling machines are the top option. They come in two different configurations, horizontal and vertical. They function almost identical tasks with the key difference being how they are installed and configured. It refers to the positioning of the boring tools and the placement of the workpieces. In this article, let’s focus on the horizontal boring machines.   



Uses And Parts of A Horizontal Boring Machine


Horizontal boring milling machines are usually used when the boring operation is to be done on bigger parts. Apart from boring, the machine is also used for shaping, facing, drilling, and milling purposes. It is often employed if parts are very large and a crane is needed to be placed overhead. Under this boring mill configuration, it is the tool that rotates while being mounted on the spindle, while the cutter is being adjusted on the bar according to the desired dimension. Here is a list of the different boring mill parts and their functions.




The bed is usually placed to support the working table and the column. It’s typically made of cast iron to provide the necessary strength to support heavy workpieces.  




The table is where the workpiece is placed during the entire boring operation and offers a good surface to hold the various parts of the boring milling machines.




This part is the one that holds the boring tool and moves upward and downward to settle the tool on the specified height of work.




This is what enables the workpiece to move in a longitudinal motion while on the bed as well as control the speed of the movement.


Boring Bars


This part holds the spindle, the cutter, and column that supports the boring operation.
