Drilling, tapping, countersinking

Drilling, tapping and countersinking on modern CNC cutting machines


CNC-controlled drilling is used in industrial manufacturing to produce precise cylindrical holes. With a cutting-drilling combination, sheet metal panels can now be drilled, countersunk and then cut out with just one machine. In this way, for example, head plates, saddle plates or flanges can be produced. Typical areas of application are industrial sectors that process drilled components into structures or finished products.

Bohren, Senken, Gewindeschneiden, AusschneidenDrilling, countersinking, thread cutting, cutting out: MicroStep cutting systems can combine all of these processes in just one system without compromising on the quality of the components to be produced. The advantages of such a combination of different processes are obvious: no time-consuming component handling to the next system, no further clamping and no reprogramming of the component on the cutting system - the entire processing takes place on one system.

This is made possible by the promising cooperation between MicroStep and technology leader Kennametal. Users benefit from this in many ways: short distances and the optimal coordination of the CNC cutting system and tool components ensure a high degree of accuracy and enable the implementation of special solutions.

After drilling, the system automatically switches to the cutting tool (e.g. plasma) and cuts all planned contours (2D and 3D).

Two things are particularly important for the high precision of the finished component: firstly, the width of the kerf must be taken into account when measuring the distance between the drill hole and the outer contour - an exact measurement of the torch tip is necessary for this. Secondly, the control system must precisely determine the offset between the torch and the drilling tool. Both are carried out using the patented ACTG® calibration unit from MicroStep.



With the combinable tool systems, the MicroStep system can drill and countersink between 4 and 60 mm in diameter, depending on the equipment. The drilling components from the manufacturer Kennametal enable through-holes, blind holes and flat-head countersinks. In addition, systems can be integrated to deburr and prepare defined chamfers simultaneously during the drilling process.


In addition to blind hole and through-hole threads, threads from M5 to M30 can be cut into the material, depending on the system.


In order to increase the process speed to a maximum, it can make sense to integrate and use a step drill for numerous applications. This is individually manufactured by the drilling expert according to customer requirements and the drilling job. By integrating several fixed tools into one, not only process steps but also tools can be saved.
