The 3 Main Tasks of Horizontal Boring Mills

The 3 Main Tasks of Horizontal Boring Mills

If you are familiar with turning lathes, then it is quite likely that you will easily understand how boring mills work. However, unlike lathes that machine the external diameter of a workpiece, vertical or horizontal boring equipment cuts the inside part. So, essentially, a boring mill is used to finish up a pre-existing drilled hole on a workpiece.

Its main function is to attain three important machining goals - correct sizing, straightness, and concentricity of the bored part.

Proper sizing of the hole with the use of a boring mill should be done when the inside diameter of a part is not of a standard size. Any diameter can be achieved by adjusting the horizontal boring equipment within the work envelope of the machine, which is typically bigger than those of other types of machines. This will also ensure the straightness of the original hole because the spindle can reach far into the cavity or the cutting tool can be moved straight in one direction.

How does it work?

A boring machine may look so complex but its functions are quite straightforward. Its spindle moves along the different axes of the machine, depending on how it has been mounted. The specific type of application also determines the layout of the boring machine. For example, horizontal boring equipment comes in three types depending on the application: bed-type, floor-type, or ram-type. The shape of the workpiece also determines if a horizontal or vertical boring mill is needed for the operation.

What is the difference between vertical and horizontal mills?

Vertical boring mills, also called as vertical turret lathes, feature a rotating chuck which holds the workpiece and a spindle which stays stationary during the machining process. A horizontal boring mill, on the other hand, is more versatile since the workpiece can be extended beyond the work envelope. Unlike in the vertical version, it is the spindle that moves and the workpiece that stays in place in a horizontal boring mill.
