Thanks to the synergy with Intermac and the development of a specific software, the descent of the tool is no longer vertical but occurs with a spiral movement; the entrance is through the upper part of the tool, and instead of being drilled, the glass is ground to create a hole. Once the hole is completed, side grinding starts, enlarging the hole up to the nominal dimension. After this stage, the lower and upper countersinking starts and any imperfection is deleted. Helix System is available on the CNC work centres range built from 2005 onwards.
Helix system is a patent pending solution of Biesse Group.
