The rapid radial drilling machine is a drilling machine with increased drilling capacity. These machine tools are characterized by higher speeds, faster feed and higher stiffness compared to a simple radial drilling machine. Although holes can be machined with lathes, milling machines and CNC machining centres, rapid radial drilling machines have a firm place in industrial metalworking. With these drilling machines, it is possible to efficiently produce repeatable, distortion-free and straight hole-patterns even in compact workpieces. At Surplex you can find used radial drilling machines and rapid radial drilling machines from renowned manufacturers such as DONAU or HELLER at a fair price!

A rapid radial drilling machine is a type of pillar drill. The large difference between the box column drill and the pillar drill is that the box column drill contains a round guiding column, and the pillar drill has a square column with guides. This type of machine enables the production of both the threading and galling of drills on one machine. Contrary to the conventional box column drill, this type of machine contains a continuous speed control for the main drive shaft of the drilling tool. Additionally, the feeding rate is adjustable. The rapid radial drilling machine contains a specifically engineered machine frame (which is encased) to ensure minimal vibrations. The cooling device is also located within the casing. In some drilling machines, this can also be located separately, next to the machine. The strong machine frame can be adjusted by height. The guiding pillar is protected by a bellow. On the top of most models one can find the controller for the tool spindle on one side and the spindle head on the other side.

A morse taper is used for the clamping in of the workpiece, and it allows the tools to be quickly switched. The continuous, adjustable spindle speed control is often combined with gears for certain sectors. Secure clamping of all axles is usually done hydraulically, in order to ensure minimum vibration during drilling and extend tool life.

The electric drilling machine has been around since 1895 as a hand drill. The radial drilling machine started to be used at the beginning of the industrialisation in industry countries. This type of machine is used for the processing of heavy and large workpieces.

The drilling head is adjustable three-dimensionally and a can also be clamped in. A stable drilling table contains T-slots as a receptacle for a vise and special clamping devices.

This machine has basically had the same construction for several decades with necessary developments continually being added. Continuous speed control over equal frequencies and an automatic feed increase the effectiveness of these machines. An automatic depth stop and torque monitoring are both new features of this machine. In the last decade there have been developments in this machine, including the addition of a display for quill adjustment and other parameters like the spindle speed and the feed rate.

These industrial machines are mainly used in the metalworking industry and in workshops. The precise design allows it to handle drilling tasks that are not so effective due to the construction of the drilling tools. Therefore, rapid radial drilling machines are use in all branches of the metal processing industry for the economical production of drills. This includes the manufacturing of casings, production of components for machines, in the steel industry and for producing tools.

Several companies have specialised in the manufacturing of rapid radial drilling machines. Some of the most recommended suppliers include DONAU, WEYRAUCH, IRSASA, HKS, GENKO, RAPID, HELLER, GIRADS, SCHLUMBERGER, EFI, HUVEMA, and PLANK.
