What is a "deep hole drilling machine"?

The act of deep hole drilling consists of a metal piece of machinery drilling very deep into the ground. The most important aspects to consider when working with a deep hole drilling machine is the contours, that the drill maintains a straight path and that the cross-section is precise. Transporting the rock chippings out of the hole is particularly problematic in deep hole drilling. Special procedures using specific drilling tools have been developed to ensure that the chippings do not block the drill.

Functions of a deep hole drilling machine

After reaching a depth of just a few inches with a normal drill, the spiral in the drill causes chippings to be brought to the surface. Once the chippings are at the surface, they can be removed through the use of air pressure or a cooling lubricant system. Due to the length of the drill required for deep hole drilling, the build up of chippings can end up blocking the drill. Therefore, deep hole drilling tools, called "single lip drills", have been developed to combat this problem. They are not in the shape of a spiral and have a channel running down the length of the drill, where a large amount of pressure forces cooling lubricants down to collect all the chippings, bringing them up to the surface. Large storage facilities are needed for the filtering and circulation of the cooling lubricants, in comparison to conventional lathes. There are a large variety of deep hole drilling machines. Those with removable plates are particularly economic, because they can always be newly assembled.

Building a deep hole drilling machine

A deep hole drilling machine is made out of a drilling machine and a clamping device. The drilling process mostly occurs horizontally, which is why the deep hole drilling machines require a lot of space for operation. The drilling mill is equipped with the desired drill and installed on the machine, above the spindle guide. By the means of CNC control, it then drills the desired holes.

Areas of operation for deep hole drilling machines

There are a large variety of uses for deep hole drilling in metal materials. Usually in these occasions, it involves drilling in canals that are flowing through a medium. That is why, for example, hydraulic manifolds are often manufactured for deep hole drilling processes. Other applications are the insertion of cooling channels in big engine blocks or generations. Drilling does not necessarily have to be the last step in the process.

With deep drilling, it is possible to add other configurations to the hole, for example, incorporating a thread, gutter or polished surface. Precision instruments are generally manufactured onto a deep hole drilling machine. These should only be installed by trained machine mechanics.
