What is Boring?

In machining, boring is a precise cutting process used to enlarge and refine pre-existing holes in a workpiece. It is typically performed after drilling or casting a starter hole, to achieve an accurate diameter, tight tolerances, and a smooth finish. Boring is commonly done on lathes or on milling/boring machines. By removing small amounts of material from the interior surface of a hole, it corrects any inaccuracies from drilling and ensures a perfect fit.

The key advantages of boring include high precision, excellent surface finish, and the ability to achieve tight diameter control. Boring is especially useful when you need precise alignment and roundness in holes, and it’s essential for manufacturing parts like engine cylinders, hydraulic cylinders, and other components that require smooth, accurate internal cavities.
