This article is a way for us to share our experience with making holes in different ways, using a range of machines, from simple to more exotic, found across our shops. We hope it&#;s useful to you to help sort out the complexities of what can be a pretty simple process!
You probably already know that a drilling machine is used to make holes. The machine's purpose is to hold a drill bit or other form of cutter rigidly and traverse it along the spindle axis to cut the required holes. In reality, some machines move the workpiece rather than the cutter, while others can move both as required.
A drilling machine's speed is necessarily adjustable, to suit the type of cutter, the material being worked, and the precision/surface quality needed in the hole. The feed or plunge rate into the workpiece can be altered either manually or automatically, depending on the complexity of the machine you&#;re using.
Drilling machines can be mounted directly to a concrete floor or a work table, or they can even be portable or for freehand use. We have seen it done in multiple ways.
