The drilling module is simply ingenious, because 5-axis helical drilling becomes as simple as helical tilt milling. The milling cutter is tilted forward in the direction of motion, and a second inclination helps to avoid collisions with the bore wall.
This strategy is excellent for making an opening cut when roughing deep cavities. Moreover, no predrilling is required. Removal of material from circular pockets is particularly effective while putting very little strain on the milling cutter. With thanks to this 5-axis simultaneous machining strategy, another benefit is the ability to use non-centre cutting milling tools.
“There’s no better method for removing high chip volumes in such a short amount of time. It demonstrates yet another example of the superiority of 5-axis simultaneous machining for such a seemingly simple task.”

In contrast to conventional 3D machining, a lead angle allows for use of milling tools that are not centre cutting.
In the event of a collision, this function automatically adjusts the pitch until collision-free machining is ensured.
The task: To remove as much material as possible from a circular pocket in an efficient and tool-friendly manner.
The solution: 5-axis helical drilling.
