What is a Drilling Machine

Drilling machines or drill presses are one of the most common machines found in a machine shop. A drill press is a machine that rotates and advances a drill into a workpiece. While a drill press is primarily used for drilling holes, it can be used for a variety of machining operations when used with appropriate tools. Some of the most common machining operations performed on a drill press include drilling, reaming, tapping, countersinking, counterboring, and spot facing. There are many different types or configurations of drilling machines, but most drilling machines fall into four broad categories: sensitive upright, upright, radial, and special purpose. The sensitive upright drill press.

The upright drill press is typically a heavy-duty drilling machine that features a geared drive spindle head. This type of drilling machine is commonly used for larger or heavier workpieces requiring large hole drilling operations. The upright drill press allows the operator to feed the tool manually or feed the tool into the workpiece. The power feed mechanism automatically advances the tool into the workpiece. Some types of upright drills are also produced with automatic table lifting mechanisms. typically a light-duty drilling machine that features a belt-driven spindle head. This machine is generally used for medium-light duty jobs. The sensitive drill press gets its name because it can only be fed manually. Feeding the tool into the workpiece manually allows the operator to "feel" the cutting motion of the tool. Precision drill presses are produced in bench or floor style.

There are a wide variety of special purpose drilling machines. The purposes of these types of drilling machines vary. Special purpose drilling machines are machines that can drill 20 holes at the same time or can drill holes as small as 0.01 inch. In a gang drill machine or multiple spindle drill press, there are several working heads mounted onto a single table. This type of drill press is used when sequential operations are to be carried out. For example, the first head can be used for spot facing with a drill. The second head can be used for drilling. The third head can be used with a guide pull head for tapping the hole. The fourth head can be used for chamfering.
