Understanding the Workings of Horizontal Boring Mills

Understanding the Workings of Horizontal Boring Mills

In almost all manufacturing plants, boring mills are indispensable machines that handle a number of different processes. The two most popular types of this machine are the horizontal and vertical boring mills which are both used extensively in manufacturing and prototyping work. However, reliable horizontal boring mills are safer and easier to use than their vertical counterparts. It helps to improve both the quality and efficiency of boring operations. Apart from boring, it can also perform other different applications with suitable tools.


Horizontal boring mills are also utilized in reaming, milling, turning, facing, threading, grooving, and more.


They are perfect for the purpose of easily holding and machining heavier or asymmetrical workpieces. They also come in many types designed to meet different purposes. Despite the variety of designs, the basic parts and setup of the horizontal boring mill remain the same. Here is how each part of the equipment works effectively together to make your business operations run smoothly and efficiently.


-        Head Stock: this is considered to be the most essential part of a horizontal boring mill. It consists of spindles that hold, drive, and feed the boring tool. For backing out tools, the spindle rotation is simply reversed.

-        Column: this is the part that supports and balances the headstock as well as guides its movement through many ways. Columns are hollow and heavily constructed and are keyed and bolted to the bottom base of the machine.

-        End support column: this part of the horizontal boring mill is essential for long boring operations and for when heavy boring tools are required. There is an outboard bearing that supports the other end of the bar and is available either as an opened or closed type end-support.

-        Runways: this is where the column traverses when at work. Its key function is to carry the main column, end support column, or the rotary table.

-        Table: this is very important for holding workpieces rigidly for the whole duration of the operation. It moves perpendicular to the axis of the spindle and uses a variety of suitable ranges of feeds and quick reverse mechanisms.
