MAXXimum Drilling

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 using our innovative drilling module.

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 pre-drilling 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.”

Lead angleLead angle

In contrast to conventional 3D machining, a lead angle allows for use of milling tools that are not centre cutting.

Automatic pitch adjustmentAutomatic pitch adjustment

In the event of a collision, this function auto­matically adjusts the pitch until collision-free machining is ensured.
