APPLYING LOGIQ TO DRILLING

Iscar’s recently launched Logiq campaign introduced new families of cutting tools targeted to address challenges in metalworking, from increasing efficiency and developing cost-beneficial small-size tool solutions to reducing machining vibrations.

One of the issues confronting Iscar’s specialists was: how to increase productivity in drilling? Although a traditional approach, based solely on advanced cutting geometry and progressive tool materials, can result in some improvements in productivity, it is still far from a dramatic change. A significant breakthrough calls for another concept.

The development of the Logiq3Cham family of drills with exchangeable heads offers a solution to this challenge. The drills feature heads with three flutes instead of two, which is the standard number in a drill design. As a result, machine cycle times can be reduced by up to 50 per cent when compared to the conventional two-flute drills. The idea looks logical and simple - more flutes means more feed speed, which leads to higher productivity. However, a translation of this idea into action is not as easy as it may seem; ISCAR’s engineers had to solve several complex tasks to design a robust and reliable three-flute drill.
